10 Manual Testing Interview Questions and Answers for Software Testing

In this article, I shed light on the common questions interviewers ask when they examine your software testing skills. These are insights taken from experts in the industry who have seen it all and can tell you what to expect. We want to hear from you. If there are any questions not answered in this article, please share them with us by commenting below.
Be sure to prepare for your upcoming interview with our comprehensive list of manual testing questions. With the help of this guide, you can learn more about what differentiates a fresher from an experienced tester and also get answers to some key problems in manual software tests such as identifying bugs that cannot be reproduced or occur sporadically without any common pattern.

1. What are the stages of the software testing life cycle (STLC)?

The different phases involved in the software testing life cycle are:
Requirement Analysis – This phase is where a QA team understands what requirements need to be met and identifies testable ones.
Test Planning – In this step, there is a creation of an effective strategy for tests that will fulfill necessary criteria before the release date.
Test Case Development- Detailed plans about how each piece or function should work with one another as well as accurate predictions on possible failures can all be made here through detailed documentation provided by teams who have been tested themselves beforehand so they know best exactly which aspects may not meet standards when it comes down to execution time.
Environment Setup- It’s important for new environments (hardware & software) set up specifically according to company specifications
Test cycle closure -includes evaluating all aspects from cost, time, and more importantly how well a product has been tested for bugs or errors in its programming code before releasing it out into the world.

2. Define exploratory testing

Exploratory testing is a hands-on approach in which testers are involved in minimum planning and maximum test execution. The plan involves the creation of a “test charter” that states the scope of short (1 to 2 hour) time-boxed tests, as well as objectives and possible approaches to be used. Testing design activities take place alongside these activities without formally documenting results or case files so they can run smoothly together typically with no break between them.

3. What is Equivalence partitioning testing?

Equivalence partitioning testing is a software testing technique that divides the application input test data into at least one equivalent data from where test cases can be derived. By this method, it reduces the time required for checking out your product.

4. What do you verify in white box testing?

White box testing is used to verify the security holes in code, incomplete or broken paths, and flow of structure according to document specifications. It also verifies expected outputs for every conditional loop within an application. Each line of coding must be verified by a tester as they cover 100% percent coverage during Whitebox testings.

5. What do you mean by black-box testing?

Black box testing is a powerful way to check the functionality of any application. For example, equivalence partitioning involves dividing an input into smaller categories that will give you different outputs. Boundary value analysis checks both extremes while cause-effect graphing helps finds out what error messages are coming up in your software when it crashes!

6. What are the different levels of testing?

As the developer, you have four main levels of testing to get through before your deliverables can be handed over. The first and most important is Unit Testing which ensures that all components are working properly together. It’s followed by Integration Testing, System Testing, and Acceptance Testings where the workflows align with what users want to do on a day-to-day basis in their jobs or lives so they’re satisfied when they use it for themselves.

7.  Define verification and validation in software testing

Software verification is a process of evaluating software at the development phase to decide whether or not it satisfies specified requirements. Validation, which happens after building and just before releasing an application to customers, can provide assurance that our app meets customer needs.

8. What is usability testing?

The correct way to gauge the usability of a product is by asking your target customer demographic. A more accurate approach, however, might be using either prototype or mock-up software during the initial stages for insight into their perception and time required on certain tasks.

9. What is the difference between UAT (User Acceptance Testing) and System testing?

System Testing: System testing is a process of finding defects in the system. It’s done by making sure that each part works together and has no errors as well as checking if it meets goals, objectives, requirements, and specifications during the whole process with different types of tests. User Acceptance Test (UAT) involves running products through various tests to determine whether they meet user needs.

10. What is fault-masking?

Developers will often find themselves in a situation where one defect masks another. For example, if the NegVal causes an unhandled system exception to fire and this is not prevented by the developer then it’s possible that they may be masking their own fault of allowing such behavior.
