Root Cause

使用assert_called_once_with或assert_called_once时，mock没有被调用或调用次数不符。

generic

中文

使用assert_called_once_with或assert_called_once时，mock没有被调用或调用次数不符。

Workarounds

  1. 90% success 
    print(mock.call_count)
print(mock.mock_calls)
  2. 85% success 
    mock.assert_any_call(args)

Dead Ends

Common approaches that don't work:

  1. 60% fail

    return_value是返回值，不是调用记录

  2. 70% fail

    如果代码逻辑错误，增加调用次数是错误修复
