PCET-30-01 Exam Dumps – PDF Questions and Testing Engine [Q22-Q38]

Q22. Which two are examples of white-box testing techniques?

Code path analysis

Boundary value analysis

Statement coverage

Equivalence partitioning

Q23. What happens if an assert statement fails during program execution?

Execution continues

A SyntaxError is raised

An AssertionError is raised

Nothing

Q24. A developer encounters an unexpected error in a Python function. They use pdb, inspect variables, set breakpoints, and finally resolve the issue by modifying a loop condition.
Which debugging steps were likely involved?

Trace stack analysis

Logging with info-level severity

Step into function calls

Conditional breakpoint setting

Output assertion validation

Q25. What does the principle “Defect clustering” imply in software testing?

All defects are evenly spread across the application

Defects tend to be found in a small number of modules

Defects always occur due to the same root cause

Every test case will detect at least one defect

Q26. In the test pyramid, which layer typically contains the largest number of tests?

Manual UI tests

Unit tests

End-to-end tests

Performance tests

Q27. Which type of test coverage metric ensures that all decision outcomes in the code are tested?

Branch coverage

Statement coverage

Line coverage

Module coverage

Q28. Which term best describes a tester applying domain experience to guess potential error-prone areas?

Scenario modeling

Boundary partitioning

Error guessing

Mutation analysis

Q29. Which of the following are valid purposes for using test doubles?

Replacing external dependencies

Generating test reports

Isolating code under test

Improving UI rendering speed

Q30. During testing of a finance app, testers notice that repeating the same test cases no longer uncovers new defects. They shift strategy to exploratory testing and user-based feedback.
Which testing concepts or principles are demonstrated?

Pesticide paradox

Black-box testing

Experience-based testing

Defect clustering

Validation

Q31. In what situations are assertions most effective?

Validating user input

Internal function validation

Postcondition checks

Error logging

Q32. Which of the following is a type of non-functional testing?

Unit testing

Load testing

Regression testing

Integration testing

Q33. Which of the following best describes the relationship among error, defect, and failure?

Error leads to failure, which leads to defect

Failure leads to defect, which leads to error

Error leads to defect, which may lead to failure

Defect leads to error, which causes failure

Q34. Which scenarios might trigger the need for code refactoring?

Duplicate logic found in multiple modules

Style guide update

Code that is difficult to test

Fully documented code

Q35. Which of the following are advantages of black-box testing?

No need for code knowledge

Can validate business requirements

Easy to test all paths

High code coverage

Q36. Which are valid logging levels in Python’s logging module?

ERROR

INFO

TRACE

DEBUG

Q37. Which of the following best describes a test case?

A summary of test outcomes

A repeatable set of steps used to validate a feature

A code review artifact

A test goal specified by the customer

Q38. Why is software testing essential in modern development practices?

It accelerates product launch without risk

It ensures security and performance compliance

It validates that requirements are implemented correctly

It prevents the need for refactoring
