how can I know which assertion failed ?

Hi guys, don’t know if it’s a Chai question / Mocha, but I am facing a very basic issue that I feel like i’m missing something.

Some of my tests have more than a few assertions and when some of them fail all I get is something like AssertionError: expected true to be false.

Is there any way to know which assertion failed ? Line number / stack trace perhaps ?

I know I can add a text description to each assertion but I don’t want to clutter my test files with unnecessary text just to mark which assertion failed when a line number would be sufficient.

Right now I am just commenting out assertion and re-running tests just to find the faulty one. I feel stupid when I do that…

Thanks 👍

I actually do see that in some cases Mocha gives me a line number (greyed out below the assertion). For example when running the assertion

expect(res.body.code).to.equal('something');

I get

AssertionError: expected 'success' to equal 'something'
      + expected - actual

      +"something"
      -"success"

      at Context.<anonymous> (order-test.js:239:30)

But in other cases when I run for example the assertion

expect(res.body.data.user.can_buy).to.be.true;

I simply get

1) should charge successfully


  0 passing (8s)
  1 failing

  1) charge should charge successfully:
     AssertionError: expected false to be true

Seems this has been resolved but let us know if otherwise.
