Fix AssertionError

✅ Solution

AssertionError in pytest usually indicates that a test's expected outcome doesn't match the actual result, signifying a failed assertion. To fix it, carefully examine the traceback to identify the specific assertion that failed and then adjust either the expected value or the code under test to ensure they align, or alternatively use `pytest.approx` to allow for small numerical differences. Debugging the test or the tested function is crucial to pinpoint the root cause of the discrepancy.
