In RSpec 3 you can setup multiple conditions at once (so the single expectation rule is not broken).

Hence the error message: “Illegal repetition”. You should escape them: “\\{\”user_id\” : [0-9]*\\}”. And since you seem to be trying … Read more
For Java 8 and above, it’s easy: when(mock.process(Matchers.anyList())); For Java 7 and below, the compiler needs a bit of help. Use anyListOf(Class<T> clazz): when(mock.process(Matchers.anyListOf(Bar.class)));
Two more ways to do it (see my comment on the previous answer by @Tomasz Nurkiewicz): The first relies on the fact that the compiler simply won’t let you pass in something of the wrong type: when(a.method(any(Class.class))).thenReturn(b); You lose the exact typing (the Class<? extends A>) but it probably works as you need it to. … Read more
