[xwiki-devs] [Proposal] Use the "@Rule ExpectedException" strategy for asserting exception in unit tests

Hi devs, I’d like to propose that we use the strategy described at https://github.com/junit-team/junit/wiki/Exception-testing (thanks to Lyes for pointing out this page to me). For example:     @Test     public void sendSynchronousWithErrors() throws Exception     { ...         this.thrown.expect(MessagingException.class);         this.thrown.expectMessage("Some messages have failed to be sent for the following reasons: "             + "[[[errorsummary1],[errordescription1]][[errorsummary2],[errordescription2]]]");         this.mocker.getComponentUnderTest().send(Arrays.asList(message), session);     } I feel it’s slightly better than our current idiom based on try/catch. One advantage is that we cannot forget to put the fail(). WDYT? Thanks -Vincent
