Why is it important to pass fixtures as function arguments rather than calling them directly inside pytest test functions?

PyTest - Fixtures
Why is it important to pass fixtures as function arguments rather than calling them directly inside pytest test functions?
ABecause fixtures are only available in global scope
BBecause calling fixtures directly causes syntax errors
CBecause pytest manages fixture setup and teardown only when passed as arguments
DBecause fixtures cannot return values if called inside tests
Step-by-Step Solution
Solution:

  1. Step 1: Understand pytest fixture lifecycle

    Pytest controls fixture setup and teardown automatically when fixtures are passed as test function arguments.

  2. Step 2: Analyze consequences of calling fixtures directly

    Calling fixtures like normal functions bypasses pytest's management, so setup/teardown and other features are not applied.

  3. Final Answer:

    Because pytest manages fixture setup and teardown only when passed as arguments -> Option C

  4. Quick Check:

    Fixture lifecycle managed only via function arguments [OK]
Quick Trick: Pass fixtures as arguments to enable setup and teardown [OK]
Common Mistakes:
MISTAKES
  • Calling fixtures directly inside tests ignoring pytest management
  • Assuming direct calls trigger setup/teardown
  • Believing fixtures only work in global scope
