How do I mock away Ignition.start()

For various reasons my unit testing environment won't have access to the environment that's needed to start ignite. I don't need ignite to start for the test and I'd like for the code to just ignore the call to Ignition.start(). How do I do that?

I've tried mocking away ignition but when I try to mock away the start() method it throws an error.

when(ignitionMock.start())

This results in the following error:

org.mockito.exceptions.misusing.MissingMethodInvocationException: when() requires an argument which has to be 'a method call on a mock'. For example: when(mock.getArticles()).thenReturn(articles);

Also, this error might show up because: 1. you stub either of: final/private/equals()/hashCode() methods. Those methods cannot be stubbed/verified. Mocking methods declared on non-public parent classes is not supported. 2. inside when() you don't call method on mock but on some other object.

You could use doNothing():

doNothing().when(ignitionMock).start();
