흔히 이렇게 알고 있다

pytest.approx(0.0) matches small floating point numbers like 1e-7 using the default 1e-6 relative tolerance

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• pytest.approx(0.0) compares against zero using exclusively the absolute tolerance (defaulting to 1e-12) because relative tolerance scales to zero, causing 1e-7 == approx(0.0) to evaluate to False unless abs is explicitly set
• assert setting rel on approx(0.0) has no effect on zero comparisons while abs adjusts the allowable delta
• assert approx comparison against non-zero values uses relative tolerance scaled by the expected value
• assert approx rejects boolean-to-integer equality coercion returning False for 1 == approx(True)
• assert approx supports element-wise comparison between tuples and lists but rejects nested dictionaries and nested sequences with TypeError
• assert approx requires nan_ok=True to match float nan values
