List of Defects in Software Testing | Severity & Priority in Testing

CLASSIFICATION AND HANDLING OF DEFECTS

The defects which are also known as bugs or faults are anything that cause threading to the value, quality and aim of the software. It can be identified by the tester through the variance of expected results and actual results of execution of test cases. The defect-free software building is the impossible where the defects detected and solving the defects is the only way to achieve the defect free software. To achieve the goal the nature of the defects and the implementation methods of solving the defects should be known. Here the defects and handling of the defects in possible ways were discussed.

software testing

List of Defects in Software Testing:

Design Defects: 

The algorithms, login and data elements, module interface, the external software and hardware UI descriptions should be correctly designed. The incompatible or incorrectly designed modules lead to defects in the system.

Command Defects:  

An error in the sequences and logic is known as control flow error or command error. The reasons for such defects are missing command, wrong algorithm, incorrect data and code errors.

Boundary Value Defects:  

In case the login page is logging in by giving the passport length to 16 characters in the place of 15 characters, then the defect is the boundary value defect.

Error Handling Defects:  

The error that is raised while the users interacting with the software need to be handled in the correct flow. The flow should indicate the instruction in the popup message for the mandatory fields to alert the users for incorrect information.

Multithreading Defects:  

Executing or running multiple tasks at the time. Complex debugging is possible in the multiple threading process. It may also lead to a system crash/failure due to the condition in deadlock.

Security Defect:  

The defects will be different by their nature of the risks. These defects are weaknesses allowing for a potential security attack.

Interface Defects:  

The defects in the interactions of the software and the users. Some of the interfaces in the different kinds of forms are complicated interfaces, unclear interfaces and platform based interfaces.

Priority of Defects:

  • The impact of the bug of an application should be described.
  • It is the order of priority which the developer will resolve the defects.
  • The Priority can be changed based on the comparison with other defects.
  • At the time of UAT, defects are fixed according to the priority.

Priority can be classified as follow as:

Immediate/Critical :

This generally occurs when the entire functionality of the task is fault and no more testing can do further for the result. Any defects that need immediate attention that affects the flow of the testing comes under this category. Critical severity also fall into the same category.

High :  

The defect that does not meet the exit criteria. Due to such defects the testing of the entire application has been stopped until the defects are solved. These defects are resolved once the critical issues are fixed. This kind of defect should be resolved before the release.

Medium :

Defects occur when a particular feature cannot be used the way it should be because of defects in a program, environmental issue. These defects should be fixed once all the critical and serious bugs get fixed. These defects can also be fixed in the next release.

Low :

If few users of the feature encountered a defect such as minor UI issues, spelling mistakes, alignment issues and colour code mismatch are considered as low priority bugs. Sometimes these defects are opened to suggest enhancements in the existing design. This defect does not need any immediate actions as it can be resolved in future.

Severity of Defects:

  • It is related to the defect fixing urgency.
  • The testers will set the level of severity.
  • Once the Severity is fixed it won’t change with time.
  • It is based on the functionality that the defects affect.

Severity can be classified as follow as:

Blocker :

When the whole functions feature / functionality missing from the project applications and completely crashes the system will be considered as Blocker and these severity defects are having the highest priority.

Major :  

The implemented feature that does not meet the requirements, test cases and behaves differently than the normal flow. It does not cause any system kind of failure but not equal to the blocker but avoiding the unnecessary delay of fixing.

Minor :  

The defect will not cause a failure in execution of the applications which is not a major impact. Loss of data falls in the minor severity it also falls in major severity based on the classifications.

Low/Trival :  

The valid defect that should be fixed even though there is no impact on the functionality.

Here are some combinations of Priority and Severity:

High Priority and Blocker Severity:  

In the login page when the username and password is entered and click submit, instead of logging in the system crashes or else it throws the error message. In the Online site while adding the cart/payment options occurred in the critical times and in the final stage, this issue can impact on business at a great level.

Low Priority and Low Severity:  

Spelling mistakes which are considered as minor in the pages. Colour of the button, contents, and hovering options mismatching. Minor alignment issues in the pages that do not affect the flow much.

High Priority and Low Severity:  

Displaying the brand logo or the company logo in the company site does not impact the functionalities but it affects the value of the logo that plays the important role in the company website.

Low Priority and High Severity:  

A defect found on the social networking site as the beta version of a new feature is released with not many active users using the facilities as today. Though this defect is having a functional defect, as it does not impact the customers directly.

Some of the other Defects are the following:

Extra Defects:  

This is usually issued from the project specification without the knowledge in the documentation, but it also may be requested by the end users. It is considered a defect as it does  not meet the existing requirements.

Wrong Defects:  

These defects arose due to the misunderstanding within the project team, client and non clearance of project documents. The falsely performed requirements come under wrong defects.

Missing Defects:  

A feature that is not implemented according to the specifications which means the team has not noted the clients requirements properly.

Conclusion:

It is difficult for the tester to identify whether it is a defect in deviation of the functionality or working of the software. If software is developed with no defects then there will be no need for testing but as long as the software exists in the business field there is possibility of defects found in the software due to the increasing complexity of the software.

API

Insight of Black Box Testing and Technique | Software Testing

INSIGHT OF BLACK BOX TESTING

Whenever the software is developed by the developing team the developed software is tested by the testing team by the specific organization. The testing can be differed by two types of testing where one is White box testing and other one is Black box testing. In White box testing is the method where the software is tested by using code and Black box testing is the method where the software is tested by the knowledge of the document and knowledge of coding is not necessary. How does the Black box tester do the software testing without coding knowledge? The following question can be well answered here in the detailed below.

image (3)

Black box testing

Black box testing is a method of software testing in which the tester is unaware of the internal structure or code of the software where only the exterior functions checks and no code checking involved. There is no bothering about the interior functionality of how the system is performing. We need to focus on what will be the input and what will be the output. There will be no idea what is going on behind the system.

The method of test can be applied to each level of testing such as Unit testing, Integration testing, System testing and Acceptance testing.

It is also known as specifications-based testing. Independent testing teams usually perform this type of testing during the Software testing life cycle.

Works

Examine the requirements and specifications of the system thoroughly. Then the tester understands the requirements of how the process to work and explores the system’s UI and functionality. In the next stage, the tester will efficiency of the software by giving input and getting the corresponding output.

Tools

  • QTP
  • Selenium
  • Loadrunner
  • Jmeter

Types

  • Business Acceptance Testing- Tests that are based on requirements scenarios written by business users.
  • Performance Testing- Tests to see how the application performs like speed, response time, cpu usage and memory.
  • Penetration Testing- A person with hacking knowledge and has the authentication to perform the test to access the system or to down the system.

Want to learn how to setup agile frame work for testing ?  Contact us and speak to our consultants.

There are n-number of techniques applied in the black box testing:

  • Syntax Driven Testing:

    This type of testing applied to the system that can be syntactically represented by some language. Verifying the given input is syntax correct or not and no bother about how the syntax will impact logically.

  • Equivalence Partitioning:

    Groups the similar kind of a program into one group and then perform the testing over there. The idea is to partition the input domain of the system into a number of Equivalence classes, such that each member of a class works in a similar way. Once we identify any kind of error on the group of programs, we just realize all the similar kinds of programs will face the same issues because of grouping the similar kind of programs into one group already.

  • Boundary Value Analysis:
    Whenever we test any software, the boundaries have to be focused in every key process. When entering a value between any range, first we have to check the first value and then to check the last value to conform the boundary working fine. Boundaries are very good places for error detection. The efficiency of testing improves and probability of finding errors also increases if test cases are designed for boundary values of input domain.
  • Cause Effect Graphing:
    This technique actually identifies the cause of the particular problem the identified the error will have a cause, corresponding actions for that cause is the effect. Finding the cause and the effect and finally map in the graph which can be a boolean graph.
  • Requirement Based Testing:
    Collects the requirements from the customer and just builds up the project based on the customer requirement. Need to ensure whether the proper requirements collected from the customer, whether we are building the same product or not, that kind of evaluation is performed over here. Validating the requirements given in the SRS document.
  • Compatibility Testing:
    When we design a website in a laptop for some better resolution and to run the website in any kind of devices like mobile, tablet, different size of laptop the effect should adjust the own size and quality based on the devices using. Whether it performed or not or showing some incompatibility error or unable to use features in a very efficient manner, these kinds of testing done here. Feeding the program and testing with different devices and size and varieties and checking all the functionalities perform well or not. If any deviation in the quality on any different devices, then we have to record the results and to work on it.
  • Error Guessing:
    It is just like a tester guesses the bugs and reports from their own application, knowledge of the application, results from previous life cycles, customer issues, with previous release and risk reports.

Advantages

  • Deep knowledge of code is not required to execute a test.
  • Testing can start once the project is developed.
  • Tests done from the user’s point of view.

Disadvantages

  • Takes more time and cost.
  • Difficult to design test cases for complex projects.
  • Possibilities to miss any module in the project.

Conclusion

Black box testing is a productive testing approach for applications, software that ensures the qualities of the intended functionality from the user’s perspective.

Testing Best Practices

Know all the testing best practices to be successful in the IT industry

If you want to be competitive and successful in the IT industry, it is imperative to have testing best practices. It may cost money and time, but without it, releasing a product with a critical bug may cost multiple times. Also, it may damage your marketing and company image to irreparable levels.
In a recent Tricentis report, the software failures caused 1.7 trillion USD losses affecting 3.6 billion people and a cumulative total of 268 years of downtime. Hence, to improve the quality of the software products, the best testing practices will enhance the business and financial performance.

Importance of testing best practices

Many companies now want to be agile, fast through DevOps, shorten the life cycle to go to the market quickly, integrate all the tests in the CI pipeline, and be generic enough to test multiple environments. Without the testing, best practices may lose time and money with inferior quality of software products without the risk coverage.

As per the research reports, the root cause of many software startup failures is insufficient quality assurance during the software development process. Even minor mistakes in it may cause releasing inferior quality products to the end customers. The recent cyberattacks also prove the paramount importance of testing best practices for any software life cycle.

The testing best practices

Since it is now beyond doubt that the testing best practices are of crucial requirement, check out the following testing best practices.

  • Plan and start testing activities as early as possible in the SDLC to identify bugs which found later may cause loss of time and costs.
  • Carry continuous tests throughout the SDLC and not wait until the QA to make the developers confident for creating innovations in the product
  • Test one thing at a time with a precise aim and focus more on features like the user interface, security among others
  • Break the tests into smaller iterative tests like UI, UX, function, security tests throughout the SDLC as it will save time and resources
  • Write all tests for good and unexpected conditions, even during the requirements and design steps for maximum coverage. Avoid programmers from writing tests or test cases to reduce the chances of lacking creativity and biased tests to make the tests carry their perspectives.
  • Do not test the application within the development environment when the designers and developers make continuous changes, especially following the MVC paradigm for complete unbiased testing.
  • Customize testing solutions as per the project needs and their use cases as modules running in different devices and use cases differ from one another
  • Combine automated and manual testing to determine which test is most relevant for all the aspects and stages of the product development
  • Use requirement based testing approaches and strategies like agile, security, mobile, big data analytics, and others that suit the specific test management framework to help validate and calculate the need of the testing efforts
  • Do regression tests to benefit quality assurance, as recent additions to the code repository may interfere with the previous tests’ features.
  • To keep track of all the tests conducted and its reports by determining the data needed for reporting the bugs and its effects on the entire system and the solutions that make o the tests useful
  • Use bug tracking tools for tracking the QA metrics data for leveraging analytics to develop alternative test methods to solve many issues
  • Use unit test parallel to save time and ensure that individual components of the app work well and start integration test to assess how well all subsystems function and use functional tests to perform end-to-end scenarios for getting the feel of the UI.
  • Find the right secure environment for tests as per the need, including the different devices, user profiles, OS, and others to avoid the internet and cloud-based vulnerabilities.
  • Testing and development teams should work in tandem to have maximum communication and seamless integration of a product testing environment to reduce issues and improve quality
  • Clean the test code after making testing to change the core code for saving time and resources of doing it during the deployment of the product
  • Have skilled functional and automated testers in the team with diverse talents in their respective areas like LoadRunner, JMeter, UFT, HP ALM, Selenium for advanced testing
  • For successful testing, it is essential to mix in-house and offshore teams to meet consumers’ requirements and behaviors or uses of products in different demographic locations
  • Recycling and reusing test procedures and test automation projects will enhance the product’s quality and efficiency and save time, effort, and costs.

The above testing best practices will surely help you save time, costs, resources, and efforts to bring high-quality product fast to the market to sustain and be successful in the IT market. For more new testing approaches and strategies, it is advisable to contact the best test management company.

Agile Requirements Design

Agile testing is a software testing methodology where the testing is carried out as and when the development is made or the changes are being made in the already existing software. Hence, testing is done continuously when the new features are being added. This testing methodology requires coordination and communication between developers and testers.

Agile Requirements Design is nothing but an end-to-end requirements gathering,

agile-image

test automation and test case design tool which drastically reduces manual testing effort and enables organizations to deliver quality software to market earlier and at less cost. It is an industry-proven, continuous testing tool used to create models and generate test cases to help development and QA teams unlock the full value and capabilities of Model-Based Testing (MBT).

Agile requirement design can model both, negative and positive test cases and automation scripts

Advantages of Agile Model

  1. Customer satisfaction with least defects and fulfilled requirements
  2. Changes can be easily made when the project is under development
  3. Late changes can also be worked upon
  4. Agile testing requires limited planning to be done beforehand
  5. There tends to be communication between business people and developers.

Disadvantages of Agile Model

  • It is difficult to assess the amount of effort required at the beginning of the software development life cycle.
  • Only senior programmers are capable of taking the kind of decisions required during the development process. Hence it has no place for newbie programmers, unless combined with experienced resources.
  • The project can be taken off track as and when the customers are not sure about the final outcome that they want.

Agile requirement Design

The Agile requirement design does not require a language such as JAVA or PHP as agile usually refers to principles that are applied during development. Agile is a toolbox which provides a set of methods which help the developer in reaching the developer goals. The process requires extensive interaction between the customer, business analyst or whoever produces the requirement from the client. The work has to be carried out under proper documentation. Agile requirement Design allows to generate executable automation scripts.

The idea carried out in ARD(Agile Requirement Design) is to reduce the  testing from the manual processes used when developing test cases from requirement and also to Automate the process so the testing team can keep pace with their development process.

In the case of ARD, the team reduces the process of creating and writing the test cases manually and automatically generates the optimal set of test cases and testing artifacts using MBT. MBT is a process which is carried out for automating and generating the test cases based on flow charts.

Using the ARD and MBT  method, the testers can benefit in the following ways:

  • Automatically generate data from the flowchart model
  • Import and export test cases and data
  • Adapt new test execution technologies
  • Create a model with enough details to develop the as per the given requirements

ARD has a seperate toolbox which needs to be installed in the systems. The ARD works based on the model files that have been saved in the system.

The ARD toolbox consists of a canvas where the flowchart representation of the test cases has to be created.The path is used inorder to define the start block and end block. Once the flowchart representation is done, the file has to be saved in the system locally with a name and location.  The flowchart representation consists of blocks which are used to define the step that has to be carried out. It provides an accurate test case generation.

ARD also consists of a validation tool which helps in figuring out the errors that are present in the flowchart generated.Once the flowchart is rectified with no validation errors, the test cases are generated automatically based on the flowchart.

Agile testing is recognised as an integral part of Software development. The agile requirement design overcomes the issues faced when the new requirements are being added during development/ testing. New additions can be made during the development/ testing process.

Click here to know how our customers maximize on product testing by utilizing agile testing methodologies. A good Testing team contributes to delivering a robust and successful product.

Difference between Agile Testing and Other Testing Methodologies

  • In comparison with other testing methods, agile testing has an incremental approach where previously existing functionalities are also tested with the new changes being made.
  • The coordination and communication between the tester and the customers maintains awareness of requirements for the tester for the features that are being developed.
  • The project does not require a comprehensive requirement document since there is frequent contact between the clients and the testers.
  • Agile testing method is cost effective and can be submitted in a time frame with complete customer satisfaction

The agile methodology is used more frequently in comparison to the waterfall model of testing. The agile testing can be carried out at an early stage of development. It is used most frequently when the customer is not sure about the requirements. The process of testing can be made easier as new additions are being made to the development process.

Every model of testing such as the V model , Agile model and the waterfall model has its own set of advantages and disadvantages. However, the waterfall model can be used when the requirement provided by the customer remains intact and unchanged. This model of testing can be used only when no change in requirement will be added. The V- Model can be used when the project is extremely long running and has a wide range of functionalities. The V model can also adapt to the changes that are made in requirements. However, in order to complete the testing in a short span of time with customer satisfaction even when the requirements are being changed, Agile models are extensively used.

The Agile testing method is carried out in the following steps:

  • Implementation: In the process of implementation, the model is transformed into an executable code by the developer
  • Test : The test is carried out for validation and verification by the tester
  • Deployment: It is done to ensure that it is ready to deliver and meets the requirements
  • Configuration Management: Artifacts are controlled and managed by the team
  • Project Management: Directs all the activities throughout and manages the risk and making sure the project will be delivered to the client on time

Frameworks in Agile Testing

A framework is a set of processes that has to be carried out in order to satisfy the customers and also to carry out the iterations quickly.

Agile testing uses various types of frameworks out of which the most popular frameworks are :

  1. Scrum Framework
  2. Crystal Framework
  3. Extreme framework
  4. Feature Driven Development Framework
  5. Kanban Framework

Scrum Framework:

A scrum framework is an approach to project management. Scrum might be for you if your organization is looking for a lightweight, team-based approach to agile project management. Scrum describes a set of meetings, tools, and roles to help teams structure and manage their work.

Advantages & Disadvantages of having a scrum framework:

  • The advantage is that it is easy to understand and can help to discuss issues daily.
  • The disadvantage is that the scrum framework allows only a few number of people to discuss. .It also builds pressure on workers due to short and frequent deadlines.

Crystal Framework:

Crystal is an agile framework focusing on individuals and their interactions, as opposed to processes and tools.Crystal Method involves frequent delivery, close communication, and reflective improvement.Crystal methodology is one of the most lightweight and flexible approaches to develop software.This method most importantly focuses on Teamwork, Communication, Simplicity of the product, responding and reporting correctly , reasoning.

The crystal method has three sub methods known as the Crystal Clear, Yellow method and Orange method and each of these are characterized based on the duration of the project and the number of employees involved in a team.

The crystal framework also has a few advantages and disadvantages.

  • The advantages are that it facilitates transparency and communication in the team.
  • The disadvantage is that it lacks documentation which can further lead to confusion.

Extreme Framework:

Extreme Programming (XP) is an agile framework that emphasizes producing  higher-quality software to please customers as well as the more specific goal of making life better for the engineers developing it. The extreme framework involves qualities like communication between the team members, simplicity of the project, courage to speak about what is affecting the effectiveness of the project, respect among team members and immediate feedback during the development/testing stage.

This is a cost effective method and the team members are accountable for any issues that occur.However this method does not emphasize much on the quality of the code and is not ideal when the developers are not present in the same location.

Feature Driven Development Framework :

This framework is more inclined towards progressing the features of the project. This framework is usually preferred when the project is a large scaled one.This framework is customer-centric, iterative, with the goal of delivering software results often and efficiently. FDD allows teams to update the project regularly and identify errors quickly.

This framework allows larger teams to move products forward with continuous success. The major drawback of this framework is the lack of documentation which leads to confusion and this framework cannot be used in small scale projects. Also, it is highly dependent on lead developers and programmers.

Kanban Framework :

Kanban allows the software to  be developed in one large development cycle unlike Scrum framework which is more iterative. The three basic principles of the kanban framework is to visualise the workflow, limit the amount of work in progress and to enhance flow.This method of framework is beneficial especially when the requirements keep changing. This method has shorter cycle times hence the deliveries are made at a much faster rate with customer satisfaction. The main objective of implementing Kanban is to identify potential risks that can occur in the process and fix them. Kanban’s goal is that workflow should proceed smoothly at an optimal speed.

A standard issue for failing Kanban is not taking Work in Progress limits seriously. If this is not taken into account, the overall process gets affected and the kanban framework collapses.

One such Important tool is Selenium which is used to carry out end to end testing through automation. The basic language used to automate this tool is Java.

There are various other automation tools such as Appium and HP’s QTP. These tools are used to test Desktop and mobile applications whereas web applications require a tool like Selenium.

SeleniumMethods_WebElements

Advantages of Selenium as an automation tool

The tool helps in testing the application with least time consumption

  • It is an open source which needs Java knowledge
  • The testing done using selenium gives the most accurate results
  • It works on all the browsers such as FireFox, Chrome, Opera and many Others
 

Advances in  Selenium

There are various advances in selenium that have been made such as Selenium IDE, Selenium Remote Control , Selenium Webdriver and Selenium Grid. All these versions have come into existence in order to overcome the shortcoming faced by the users.

Although selenium has a few disadvantages when compared to other automation tools, it is still considered to be the best due to its flexibility

When should I use Selenium IDE?

Selenium IDE allows users to edit, record and debug the tests. The main purpose to create Selenium IDE is to increase the speed of test case creation. It helps the users to take record quickly and play back tests in the actual environment that will run in. The interface supports multiple extensions and it is user-friendly.

When should I use a Selenium Webdriver?

Selenium Webdriver allows users to work in Chrome,IE,Opera,Firefox,Safari and many other browsers.

  • It is an open source,multiple language supports like Python, PHP, Java, C#, Ruby, JavaScript, etc. Although it has a customized script language.
  • It works across multiple OS and Cross browser compatibility.
  • It supports Multiple Frameworks  like Ant, Maven,TestNG.
  • A major benefit of automation testing with Selenium WebDriver is that you don’t need to start any server prior to testing.

How do I check the selenium version?

  1. Open TOOLS menu.
  2. Open NuGet Package Manager.
  3. Manage NuGet Packages for Solution.
  4. Click on the INSTALLED tab.
  5. Scroll down to Selenium. WebDriver.
  6. Version is on the right.

Latest version in Selenium

Selenium has come a long way and the latest version  is the Selenium 4.0 Alpha. This is the recently updated version which has proved to be beneficial to testers. The major changes made in Selenium Alpha 4 version is as follows

  • Selenium 4 IDE TNG

Selenium IDE is a record and playback feature which was not available for chrome but is available now.a plugin will allow you to run Selenium on any browser. Also, a user can now declare their own locator strategy.

There is also a new CLI runner which is based on Node JS, instead of the old HTML based CLI runner.It has the ability to execute test cases in parallel and provide information like passed and failed test cases, the time required, etc.

The new IDE runner is completely based on WebDriver.

  • Better window and tab management

Selenium 4.0 has now allowed the testers to work on two windows at the same time which was not allowed before.

We can run two different tabs in one Chrome browser session.

  • Relative locators

Selenium 4 Alpha has also upgraded the locators where we can find locators relative to other locators

  • Full Screen screenshot

Selenium did not permit to take the full page screenshot which is now possible on firefox browser. The screenshot of an entire page can be taken.

Impacts of Selenium 4.0?

In addition to these new capabilities, arriving of Selenium 4 may require few changes in your existing selenium 2.X/3.X tests,

  • The getPosition & getSize methods were replaced by the getRect method and the setPosition & setSize methods were replaced by setRect methods.
  • Now you can configure the location of your Safari driver using the “webdriver.safari.driver” system property.
  • Element screenshotting is possible in Selenium 4.
  • Fullscreen and minimize methods have been added, so that the driver window can now be full screen or minimized and all window manipulation commands are now supported.
  • Added driver.switchTo().parentFrame() – We can use it to go from the child frame to the parent frame directly.
  • Changes added to Chrome driver –
    • sendDevToolsCommand() – The sendDevToolsCommand() method sends an arbitrary dev tools command to the browser and returns a promise that will be resolved when the command has finished.
    • setDownloadPath() – The setDownloadPath() method sends a DevTools command to change Chrome’s download directory and returns a promise that will be resolved when the command has finished.
  • Changes to Firefox driver – Added installAddon(path) method to install a new addon within the current session. This function will return an “id” that can be used to uninstall the addon using uninstallAddon() method.
  • Options class now extends Capabilities class for Chrome, Firefox, IE & Safari.
  • Changes wrt to Errors such as Added ElementClickInterceptedError, InsecureCertificateError & Removed ElementNotVisibleError
