如何在Python中使用mockito和unittest来模拟方法调用？

Question

有史以来第一个问题。在

我正试图为我的FibonacciNu编写一个单元测试mberCalculatorClient.py文件并测试它是否在实例化时实际调用socket.socket(socket.AF_INET, socket.SOCK_STREAM)行。目前我使用mockito来模拟socket类。然后我实例化我的客户机，它应该调用socket。在

有人能告诉我为什么verify(mock_socket).socket(any(), any())没有接方法调用？

我看着this answer，以为我在做类似的事情，但被卡住了。在

这些是我的档案：

腓肠肌mberCalculatorClient.py在

import socket

HOST = "localhost"
PORT = 8000

class FibonacciNumberCalculatorClient():

    def __init__(self, host, port):
        self.client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        self.host = host
        self.port = port

def main():
    client = FibonacciNumberCalculatorClient(HOST, PORT)

if __name__ == '__main__':
    main()

在客户端测试.py在

^{pr2}$

当python ClientTests.py运行时，我得到以下输出：
