Example answer:
Boundary Value Analysis is a black-box technique where I test values at the boundaries of an input range. For example, if a field accepts numbers 1-100, I'd test 1, 100, 0, 101, and potentially 2 and 99, as errors are often found at these edges in manual testing.
19. What is equivalence partitioning?
Why you might get asked this:
Another key test design technique, this assesses your ability to group inputs into classes expected to behave similarly, reducing redundant manual test cases.
How to answer:
Define it as a black-box technique where input data is divided into partitions (classes) that are expected to exhibit similar behavior. Testing one value from each partition is sufficient to represent the entire partition.
Example answer:
Equivalence Partitioning is a black-box technique where I divide input data into partitions (groups) where all values are expected to behave the same way. I then select one representative value from each valid and invalid partition to test, reducing the number of manual test cases needed.
20. What is smoke testing?
Why you might get asked this:
This checks your understanding of a quick, initial test phase performed on new builds to ensure basic stability before extensive manual testing begins.
How to answer:
Define it as a quick set of tests performed on a new build to verify critical functionalities are working and the build is stable enough for further, more detailed testing.
Example answer:
Smoke testing is a quick check of the application's most critical functionalities after a new build is deployed. It's like a 'smoke test' to ensure the build isn't fundamentally broken before starting more in-depth manual testing. If it fails, the build is rejected.
21. What is sanity testing?
Why you might get asked this:
This contrasts with smoke testing and tests your knowledge of a focused test performed after small code changes or bug fixes in manual testing.
How to answer:
Define it as a narrow regression test focused on a specific functionality or module after a small change or bug fix to ensure the fix works and hasn't broken related areas.
Example answer:
Sanity testing is a quick, focused test performed after a small code change or bug fix to ensure that specific functionality works as intended and hasn't negatively impacted related areas. It's narrower than smoke testing and often done on stable builds in manual testing.
22. What are some common challenges you face in manual testing?
