PyTest - Markers

Analyze this pytest test:

@pytest.mark.xfail(strict=True)
def test_membership():
    assert 'x' in ['a', 'b', 'c']

What will pytest report when this test runs?

ATest fails and is reported as XFAIL

BTest passes and is reported as XPASS, causing test suite failure

CTest is skipped

DTest passes normally without any special mark

Step-by-Step Solution

Solution:

Step 1: Evaluate assertion
The assertion 'x' in ['a', 'b', 'c'] is false, so test fails.
Step 2: Check actual test result
Wait, the assertion is false, so test fails. But the question is about what pytest reports.
Step 3: Re-examine assertion
Actually, the assertion is false, so test fails as expected.
Step 4: Confirm strict=True effect
Since test fails, pytest reports XFAIL.
Final Answer:
Test fails and is reported as XFAIL -> Option A
Quick Check:
Failing xfail test reports XFAIL [OK]

Quick Trick: Failing xfail test reports XFAIL, strict=True affects XPASS only [OK]
