How to get Mocha to fail a test

Question

I have the following test:

it.only(\'validation should fail\', function(done) {
    var body = {
        title: \"dffdasfsdfsdafddfsadsa\",
        description:          


        

Answer 1

Use chai-as-promised, with native Mocha promise handlers.

var chai = require('chai').use(require('chai-as-promised'));
var should = chai.should(); // This will enable .should for promise assertions

You no longer need done, simply return the promise.

// Remove `done` from the line below
it.only('validation should fail', function(/* done */) {
    var body = {
        title: "dffdasfsdfsdafddfsadsa",
        description: "Postman Description",
        beginDate: now.add(3, 'd').format(),
        endDate: now.add(4, 'd').format()
    }

    var rules = eventsValidation.eventCreationRules();
    var valMessages = eventsValidation.eventCreationMessages();

    // Return the promise
    return indicative
        .validateAll(rules, body, valMessages)
        .should.be.rejected; // The test will pass only if the promise is rejected

    // Remove done, we no longer need it
    // done();
});
