我正在使用 Mockito.我想在调用未存根的方法时抛出 RuntimeException
.
I'm using Mockito. I want to throw a RuntimeException
when an unstubbed method is called.
有什么办法吗?
您可以为模拟设置默认答案.所有未存根的方法都将使用此默认答案.
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" );
}
}
请注意,您不能将 when
与此功能一起使用,因为该方法在 when
之前调用(mockito when() 调用如何工作?),它会在之前抛出 RuntimeException
模拟进入存根模式.
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,您必须使用 doReturn
才能使其工作.
Therefore, you must use doReturn
for this to work.
