Let's assume a snippet of testing code:
Observable model = Class.forName(fullyQualifiedMethodName).newInstance();
Observer view = Mockito.mock(Observer.class);
model.addObserver(view);
for (Method method : Class.forName(fullyQualifiedMethodName).getDeclaredMethods())
{
method.invoke(model, composeParams(method));
model.notifyObservers();
Mockito.verify(
view, Mockito.atLeastOnce()
).update(Mockito.<Observable>any(), Mockito.<Object>any());
}
Mockito.verify
method throws an exception if a method in a model hasn't invoked Observable.setChanged()
method.
Problem: without adding loggers/System.print.out
I can't realize what's the current method that has failed the test. Is there a way of having something similar to jUnit Assert
methods:
Assert.assertEquals(
String.format("instances %s, %s should be equal", inst1, inst2),
inst1.getParam(),
inst2.getParam()
);
SOLUTION:
verify(observer, new VerificationMode()
{
@Override
public void verify(VerificationData data)
{
assertTrue(
format(
"method %s doesn't call Observable#setChanged() after changing the state of the model",
method.toString()
),
data.getAllInvocations().size() > 0);
}
}).update(Mockito.<Observable>any(), Mockito.<Object>any());
This does the trick (simple and clear):
try {
verify(myMockedObject, times(1)).doSomthing();
} catch (MockitoAssertionError error) {
throw new MockitoAssertionError("Was expecting a call to myMockedObject.doSomthing but got ", error);
}
