Python 未使用mock.patch调用函数

我正在尝试测试连接到BluetoothSocket的BluetoothClient类。为了避免使用真正的套接字，我只想测试使用正确的参数调用套接字中的connect（）方法。使用mock.patch替换bluetooth_控制模块中导入的bluetooth模块的效果与预期不符

在我看来，调用了connect（）方法，但断言告诉我不是这样

代码： 正在测试的单元（bluetooth_control.py）： 测试（bluetooth\u control\u Test.py）： 输出：

设置
连接：sock=
测试仪建立连接插座=
FtearDown
======================================================================
失败：testEstablishConnection（\uuuuu main\uuuuuu.TestShelf）
----------------------------------------------------------------------
回溯（最近一次呼叫最后一次）：
文件“/usr/lib/python2.7/site packages/mock.py”，第1201行，带补丁
返回函数（*参数，**键盘）
testEstablishConnection中第21行的文件“bluetooth\u control\u test.py”
mock_bluetooth.connect（）
文件“/usr/lib/python2.7/site packages/mock.py”，第831行，在assert_中使用
raise AssertionError（'预期调用：%s\n未调用“%”（预期，））
AssertionError:预期调用：mock（，（'98:D3:31:B2:EF:32'，1））

两天后，我再次检查了这个问题，发现了我犯的愚蠢错误。我必须修补实际的方法，并删除断言中错误添加的括号

我不打算删除这个问题，这样也许可以帮助别人避免这些错误
