Software Testing Interview Questions and Answers for Experienced

These questions are suitable for those professionals having two to three years of experience in the testing field. These questions will help you to explore more career options and increase your salary package too.

Q1). How can you define the relationship between test phases and environment reality?

When test phases are in progress stage, environment reality becomes more significant here. For unit testing, the environment is partly real. At the same time, for acceptance testing, the environment should be 100 percent real.

Q2). Should testing be done during execution or after the execution?

Well, it is great to perform testing at earlier phases. Earlier you catch the bug; there are better chances of resolving errors without issues. For example, if you catch a defect in the maintenance phase, it is ten times costlier to fix than the execution phase.

Q3). Take an example that defects that can be removed at the initial stage were removed in a later stage. So, how will it affect the costs?

It is obvious that if a defect is found at an earlier stage, then it should be removed at the same stage. In case, it is resolved in a later stage, then costs may increase up to 20 times that depends on when you fix it. The following figure will give you a perfect idea of cost evaluation at later stages. This is one of the frequent asked software tester interview questions and answers. 

If a defect is identified and fixed during requirements and design stage, then it is quite easy to afford. On the other hand, if the same defect is fixed during the maintenance phase, it becomes 20 times costlier.

Q4). How will you define the regression and confirmation testing?

Regression testing shows that changes made to the code will not affect the other functionalities of a software application. If a software product fails due to some errors, then a new version is launched where previous bugs were fixed gracefully, it is called the confirmation testing or retesting.

Q5). How to estimate the project cost? Tell us based on your past experiences?

This is how you should answer these types of software testing interview questions to be fully prepared for your interview.  

To estimate the project costs, the following facts should be considered by a quality engineer.

  • Divide the complete project into small chunks.
  • Allocate tasks to different team members.
  • Now estimate efforts required to complete each task.
  • In the last step, validates should be estimated.

Q6). Do you have any idea of Random testing?

For random testing, data is usually generated randomly with the help of a tool. Here is the diagram to show how random data is sent to the system.

Random data is collected with the help of a tool, or you can use any other mechanism too. The system is tested with randomly generated, and results are observed accordingly.

Q7). What is BVA (boundary value analysis)?

A daily meeting in the scrum method is called a scrum. The scrum master runs this meeting, when an update on the day's work as well as the task and context for the following day are discussed.

Q137). Describe the complete TDD (Test Driven Development).

The answer is that test cases defined for the functionality to be implemented drive the development of the product using the test-driven development process. When using TDD, test cases are first established, and only then is the code necessary to pass the tests built. The code is later refactored in accordance with standards.

Q138). What is Context-driven testing?

Context-driven testing is a sort of testing that adopts test procedures and methodologies and, on occasion, modifies them in accordance with the project's specific circumstances.

Q139). What constitutes the software testing exit criteria?

Q140). Describe the Agile process in brief.

Ans. Iterative and incremental development is the foundation of the agile methodology for software development. In this architecture, the application is divided into smaller builds on which several cross-functional teams collaborate in order to provide rapid delivery while simultaneously responding to changing needs.

Q141). What distinguishes latent defects from masked defects?

 A latent defect is an undisclosed flaw that exists in the current release but is not apparent because the prerequisites for its discovery have never been satisfied. Contrarily, a disguised defect is an existing flaw that has not yet resulted in a failure because it has been covered up by another error or kept from being found.

Q142). What is Context-driven testing?

Context-driven testing is a sort of testing that adopts test procedures and methodologies and, on occasion, modifies them in accordance with the project's specific circumstances. This is among the top software testing interview question and answers you should know about.

Q149). What is Fuzz testing?

This method involves injecting random data into the system in an effort to bring it down.

Q150). How does a tool for test coverage operate?

While testing is being done on the actual product, the code coverage testing tool is running in parallel. The source code executions are tracked by the code coverage tool. We receive a thorough summary of all pending statements as well as the coverage ¯ter the final testing is complete.

Q151). Explain which test cases are written first black boxes or white boxes?

Since writing black box test cases involves a project plan and a requirement document, both of which are readily available at the start of the project, black box test cases are developed first. While additional architectural knowledge is needed to write white box test cases and is not available at the beginning of the project.

Q152). Tell us about bottom-up testing.

Bottom-up testing is a method of integration testing in which the smallest components are examined first and then leveraged to help test the larger ones. Up till the component at the top of the hierarchy is tested, the process is repeated.

It is a section of a test plan that details the sorts of testing that must be done on the application as well as how testing is done for the project.

178). What does "efficiency of fault eradication" in software testing mean? 

One of the testing criteria is the effectiveness of defect eradication (DRE). It is calculated using the proportion of found flaws to problems that have been corrected. This is an illustration of the importance of the development team in having issues corrected prior to the release.

179). What does latent defect mean?

An application or piece of software with a latent defect has a hidden flaw that cannot be discovered by the user. The application will not be rejected because the prerequisites can never be satisfied.

180). What is the software testing defect detection rate?

Defect detection percentage is one of the testing measures (DDP). Calculating the ratio of faults discovered prior to release and the number of errors discovered after a client uses the product can be used to assess the effectiveness of a testing procedure.

181). Describe the Silk Test. Why should you use it?

To test the functionality and for regression of an application, a professional tool is designed. It evaluates web, Java, Windows, and traditional client/server applications. Silk Test aids with the development and administration of the test plan and provides direct access to the database and field validation.

A Showstopper Defect is one that prevents further testing from taking place.

186). Can we review so many test cases each day?

In order to review 7*3=21 test cases, we would write about 7 test cases. And we may estimate that 25 to 30 test cases are run daily.

187). What does software testing's V model entail?

V-models are SDLC models where the process happens sequentially in a V-shape. They are also known as validation or verification models. With this approach, a testing phase is connected to each respective development stage.

188). What is a cause-effect graph?

A black-box test design technique known as cause-effect graph testing builds the test using a graphical representation of the input (cause) and output (effect). The relationships between the input and output conditions are described using a number of notations, including AND, OR, NOT, and others.

189). Describe the partitioning of equivalence classes.

The black-box testing method known as equivalence class partitioning is based on specifications. In equivalence class partitioning, a set of input data that defines numerous test conditions is divided into logically comparable groups so that utilizing even a single test data from the group for testing can be thought of as equivalent to using all the other data in that group.

190). What is boundary value analysis?

Boundary value analysis, a method for creating test cases in software testing, uses the border values of the classes from the equivalence class partitioning as input.

191). What do you mean by Defect Triage?

Defect triage is a process whereby faults are prioritized based on a number of factors, including severity, risk, and how long it will take to fix the problem.

192). What is a Stub?

Lower-level modules frequently are not developed until top-level modules have been tested and integrated during top-down integration testing. In these situations, stubs or dummy modules are used to simulate module behavior by delivering a result that has been hard-coded or anticipated based on the input variables.
