Q93. How does PyTest manage fixture teardown if an exception occurs during setup?
A. Teardown is skipped
B. Teardown code after yield is still executed
C. The test hangs
D. It triggers a system exit
Show Answer
Answer: B
Even if setup fails (before yield), PyTest attempts to execute cleanup mechanisms, though strictly yield prevents execution if setup fails. However, safe teardown is usually ensured by safe_yield patterns in complex frameworks. Note: If code before yield fails, code after yield does NOT run. If setup fails, the test errors, and teardown is not called. This is a tricky nuance. (Correcting logic: If an exception occurs in setup (before yield), the code after yield (teardown) is NOT executed).
*Correction for this specific question logic:*
Answer A is actually correct. If setup fails, teardown is not reached. Let’s rephrase the question or answer.
Revised Question: What happens to the teardown code (after yield) if the setup code (before yield) raises an exception?
Revised Answer: It is not executed.
Q93. What happens to the teardown code (after yield) if the setup code (before yield) raises an exception?
A. It is not executed
B. It runs immediately
C. It runs in the background
D. It causes a syntax error
Show Answer
Answer: A
If the setup part of a fixture fails, the teardown part (after yield) is never reached.
Q94. Which marker allows passing a reason for skipping a test?
A. reason=”…”
B. msg=”…”
C. text=”…”
D. comment=”…”
Show Answer
Answer: A
‘@pytest.mark.skip(reason=”…”)’ allows documenting why the test is skipped.
Q95. How do you enforce a fail if there are no tests collected?
A. –strict-collect
B. –fail-on-no-tests
C. –no-tests-error
D. –collect-only
Show Answer
Answer: A
‘–strict-collect’ or configuration options can be used to fail if test collection encounters errors or finds nothing.
Q96. Which test runner is used by PyTest internally?
A. unittest
B. nose
C. Its own custom runner
D. robot
Show Answer
Answer: C
PyTest uses its own powerful test runner and discovery mechanism, separate from unittest.
Q97. Which command runs tests in parallel using available CPU cores?
A. pytest -n auto
B. pytest -j auto
C. pytest –parallel
D. pytest cpu
Show Answer
Answer: A
With ‘pytest-xdist’ installed, ‘-n auto’ spawns workers equal to the number of CPU cores.
Q98. What is the default timeout value for the ‘-x’ flag?
A. 0 (immediate)
B. It has no timeout value
C. 10 seconds
D. 5 minutes
Show Answer
Answer: B
The ‘-x’ flag simply stops on the first failure; it does not enforce a time limit by itself.
Q99. Can PyTest run tests written for the ‘unittest’ framework?
A. No, only native PyTest tests
B. Yes, it is compatible with unittest
C. Only if they are renamed
D. Yes, but requires a plugin
Show Answer
Answer: B
PyTest is designed to support and run tests written using the standard ‘unittest’ framework.
Q100. Which attribute is used to store markers on a test function programmatically?
A. pytestmark
B. markers
C. tags
D. flags
Show Answer
Answer: A
‘pytestmark’ is a special list attribute that stores markers applied to a test class or module.
Conclusion
Congratulations, you made it this far! I hope you went through all 100 Python PyTest MCQs and solved most of them. To improve further, practice Core Python and OOP MCQs for writing efficient test scripts, and Pandas and NumPy MCQs for data-based testing. Thanks for learning with us!
