Asynchronous test in mocha

[silvae86]

All assertions inside the HTTP call callbacks need to be wrapped in try-catch blocks that call done(error), because at this time if there is a

res.status.should.equal(200)

inside a callback for a REST api call, the whole test suite will die. If we catch the error and call done(error), only the failed test case will be failed and others will continue.

Example:

OK

createProjectsUnit.setup(function (err, res)
        {
            try{
                should.equal(err, null);
            }
            catch(e)
            {
                done(err);
            }
        });

NOT OK

createProjectsUnit.setup(function (err, res)
        {
            should.equal(err, null); // this will throw an uncaught Error, effectively crashing the test suite before calling done().
            done();
        });

Found a good alternative, niftylettuce/check-chai, allows you to do this:

            chai.check(done, function ()
            {
                should.equal(err, null);
            });

We need to write a piece of code to make the replacements on our tests.
