Is it possible to show descriptive text if a test fail?

[ibc]

Example:

expect(fn, 'should not throw').to.not.throwException();

It could be the second argument of expect().

I second this and add the following use scenario: For example for multiple very similar checks the time & coding effort is reduced by checking with multiple expect() in one test case like this:

        browser.setValue('input[id="id_meetingproject"]', "");  // empty input
        browser.setValue('input[id="id_meetingname"]', "");     // empty input
        browser.click("#btnMeetingSeriesSave");     // try to save
        expect(browser.isVisible("#btnMeetingSeriesSave")).to.be.true;  // dialog still open!

        browser.setValue('input[id="id_meetingproject"]', "XXX");
        browser.setValue('input[id="id_meetingname"]', "");     // empty input
        browser.click("#btnMeetingSeriesSave");     // try to save
        expect(browser.isVisible("#btnMeetingSeriesSave")).to.be.true;  // dialog still open!

        browser.setValue('input[id="id_meetingproject"]', "");  // empty input
        browser.setValue('input[id="id_meetingname"]', "XXX");
        browser.click("#btnMeetingSeriesSave");     // try to save
        expect(browser.isVisible("#btnMeetingSeriesSave")).to.be.true;  // dialog still open!

If one of these expect() fails, you only see this in the console:

Uncaught AssertionError: expected true to be false

It would be great to find out which expect() did fail with a small message...

@derwok does that example currently work? I'm kind of surprised that to.be.true is able to do anything without ().

[derwok]

Sorry - i was using "chai" expect() and was thinking I use this exepct() package.
With chai I can add a descriptive message to any expect().
Plus some more cool fetures (like ommiting the parantheses behind any .to.be.true etc.)
So for me the issue is solved. ;-)

@derwok still surprised that chai manages to execute the command without ().
