Root Cause

assert_called_with requires an exact match of arguments. If the actual call includes additional keyword arguments, the assertion fails.

generic

中文

assert_called_with 要求参数完全匹配。如果实际调用包含额外的关键字参数，断言会失败。

Workarounds

  1. 95% success 
    from unittest.mock import ANY
mock.assert_called_with('[email protected]', subject=ANY)
  2. 90% success 
    mock.assert_called_with('[email protected]', subject='Hello')

Dead Ends

Common approaches that don't work:

  1. 80% fail

    This only checks the call count, not the arguments.

  2. 70% fail

    The extra arguments may be required for the function.
