我正在尝试模拟以下呼叫:
I am trying to mock the following call:
s.socket().bind(new InetSocketAddress(serverIPAddress_, serverPort_), 0);因此,我可以以可预测的方式测试当其余代码失败时其余代码的功能.我在测试用例中使用它:
so I can test what the rest of the code does when this fails in predictable ways. I use this in my test case:
ServerSocketChannel ssc = mock(ServerSocketChannel.class); when(ServerSocketChannel.open()).thenReturn(ssc); doNothing().when(ssc.socket().bind(any(), anyInt()));但是,以上内容无法与以下内容一起编译:
However, the above does not compile with:
[javac] /home/yann/projects/flexnbd/src/uk/co/bytemark/flexnbd/FlexNBDTest.java:147: cannot find symbol [javac] symbol : method bind(java.lang.Object,int) [javac] location: class java.ServerSocket [javac] doNothing().when(ssc.socket().bind(any(), anyInt())); [javac] ^ [javac] 1 error知道我在做什么错吗?
推荐答案ServerSocket没有使用对象和整数的绑定重载.它有一个需要SocketAddress和一个int的重载.我没有使用过Mockito,但我认为您可能需要:
ServerSocket has no bind overload that takes an Object and an int. It has an overload that takes a SocketAddress and an int. I haven't used Mockito, but I think you may need:
doNothing().when(ssc.socket().bind(isA(ServerSocket.class), anyInt()));最新错误是因为您试图将void传递给when方法. 文档说明,默认情况下,模拟方法上的void方法不执行任何操作.",因此您可能根本不需要此行.
The latest error is because you're trying to pass void to the when method. The docs note, "void methods on mocks do nothing by default.", so you may not need this line at all.
