問題描述
我正在使用 Mockito.我想在調(diào)用未存根的方法時拋出 RuntimeException.
I'm using Mockito. I want to throw a RuntimeException when an unstubbed method is called.
有什么辦法嗎?
推薦答案
您可以為模擬設置默認答案.所有未存根的方法都將使用此默認答案.
You can set a default answer for a mock. All methods that aren't stubbed will use this default answer.
public void testUnstubbedException() {
// Create a mock with all methods throwing a RuntimeException by default
SomeClass someClass = mock( SomeClass .class, new RuntimeExceptionAnswer() );
doReturn(1).when(someClass).getId(); // Must use doReturn
int id = someClass.getId(); // Will return 1
someClass.unstubbedMethod(); // Will throw RuntimeException
}
public static class RuntimeExceptionAnswer implements Answer<Object> {
public Object answer( InvocationOnMock invocation ) throws Throwable {
throw new RuntimeException ( invocation.getMethod().getName() + " is not stubbed" );
}
}
請注意，您不能將 when 與此功能一起使用，因為該方法在 when 之前調(diào)用(mockito when() 調(diào)用如何工作?)，它會在之前拋出 RuntimeException模擬進入存根模式.
Note that you cannot use when with this functionality, since the method is called before when (How does mockito when() invocation work?) and it will throw a RuntimeException before the mock goes into stubbing mode.
因此，您必須使用 doReturn 才能使其工作.
Therefore, you must use doReturn for this to work.
