You want to skip a test only if the environment variable TEST_ENV is set to production. Which of the following is the correct way to write this using @pytest.mark.skipif?
A@pytest.mark.skipif(os.environ['TEST_ENV'] == 'production', reason='Skip in production')
B@pytest.mark.skipif(os.getenv('TEST_ENV') == 'production', reason='Skip in production')
C@pytest.mark.skipif('TEST_ENV' == 'production', reason='Skip in production')
D@pytest.mark.skipif(os.getenv('TEST_ENV') != 'production', reason='Skip in production')
Step-by-Step Solution
Solution:
Step 1: Understand environment variable access
Use os.getenv('TEST_ENV') to safely get the variable; it returns None if not set.
Step 2: Write correct skip condition
Skip only if value equals 'production', so condition is os.getenv('TEST_ENV') == 'production'.
Step 3: Check other options
@pytest.mark.skipif('TEST_ENV' == 'production', reason='Skip in production') compares string literals, not env variable. @pytest.mark.skipif(os.environ['TEST_ENV'] == 'production', reason='Skip in production') may raise KeyError if variable missing. @pytest.mark.skipif(os.getenv('TEST_ENV') != 'production', reason='Skip in production') skips when not production, opposite of requirement.
Final Answer:
@pytest.mark.skipif(os.getenv('TEST_ENV') == 'production', reason='Skip in production') -> Option B
Quick Check:
Use os.getenv and == 'production' for skipif [OK]
Quick Trick:Use os.getenv for safe env check in skipif [OK]
Common Mistakes:
MISTAKES
Using os.environ without handling missing keys
Comparing strings directly instead of env variable
Reversing the skip condition logic
