Top Software Testing Interview Questions (2021)

Software testing is one of the most important activities in the software development life cycle process. As of now, the popularity, credibility and worthiness of software testing is at its peak, because organizations cannot afford a low-quality product at any cost whatsoever. A software tester will be given due weightage because of the high demand in the market. In this article, you will know about the top interview related questions on software testing.

Following are the top software testing interview questions:

1. What is automated testing?

It is a software testing type that uses automation tools to perform testing. Repetitive tasks can be easily automated, resulting in speed of execution and quality output. Once a test is automated, you can run it any number of times. Automation tools are used to run the software automatically, feed the input data to the system and compare the actual test results with the expected test results.

2. What is manual testing?

In this software testing type, the functionality of a software is manually verified by a tester. The test cases along with the test data that needs to be tested are listed in a comprehensive list, which a tester has to check and work upon.

3. What is black-box testing?

All the internal structure and behaviour of the software are ignored. The tester is only focused on the input provided to the system and the output that has been generated. The program’s behaviour against the specified requirements is verified by black-box testing. Based upon the software’s functionality, the test conditions are created but don’t have a clue as to how the software works internally.

4. What is white-box testing?

The system is viewed as a transparent box by a tester. The internal implementation of the system is observed, which in turn guides the test. White-box testing is typically performed during the development phase. All the finer aspects of a program are tested by a tester. The tester or developer looks at the implementation details and the source code so that the system can be tested more thoroughly.

5. What are the benefits of automation testing?

• It supports the execution of repeated test cases
• A large test matrix can be easily tested
• Parallel execution is enabled
• Unattended execution is encouraged
• Human-generated errors are reduced and accuracy is improved.

6. What is verification and validation in software testing?

Verification: It is a static analysis technique. Testing is done without the code being executed. Examples include Inspection, walkthrough and reviews.

Validation: It is a dynamic analysis technique. Testing is done by executing the code. Examples include non-functional and functional testing techniques.

7. What is usability testing?

It is a testing method where a software application is used by an end-user to know whether the product is easy-to-use and is good in terms of functionality and performance. The customer’s perception about the software application is thoroughly scrutinized.

8. What is a test case?

It is a set of variables and conditions under which a tester will ascertain whether the system under test is able to satisfy the expected requirements.

9. What is functional testing?

In this testing type, software’s functional requirements are focused upon, rather than its internal implementation. It refers to a required behavior in the system, by taking into consideration its input and output.

10. What is non-functional testing?

The non-functional requirements of a system are tested, which basically refers to a quality or an attribute of the system that has been explicitly requested by the client. These include security, usability, scalability and performance. It comes after functional testing. General characteristics are tested by non-functional testing, which is unrelated to the software’s functional requirements.

Conclusion: As you now have some idea about the questions that might be asked in a software testing interview, you will be better prepared. It is also advised to do your homework and see what all more interview related questions you can obtain from top websites/references exclusively focused on software testing. The implementation of software testing needs to be done by professionals who precisely know the technicalities of software testing. If you want to gain in-depth insights on the tremendous value that software testing brings to an organization, then just get connected with a software testing services company, who will provide tactical and specific advice of true worth.
