Because expected true, result false is not enough!

This addon aims to improve the testing experience by defining a nice message on those asserts that don't have one set by you.

As easy as ember install ember-qunit-nice-errors

When you have a test with a failing assertion and no custom message, the default error doesn't say much. As you can see by the following example test and the default ouput below:

import { module, test } from 'qunit';

module('Unit | ok test');

test('it works', function(assert) {
  assert.ok(1===3);
});

But with ember-qunit-nice-errors the message is way nicer!

If you want your error messages to include the original test file, line and column where the failed assertion is, just add the following configuration on your config/environment.js file:

ENV['ember-qunit-nice-errors'] = {
  showFileInfo: true
};

assert.ok(false)

assert.ok(false) at my-app/tests/unit/ok-test.js:17:2

Also note you can enable this only for certain environments:

if (environment === 'development') {
  ENV['ember-qunit-nice-errors'] = {
    showFileInfo: true
  };
}

If you fully trust us you can add this option to replace all assertions within your project tests, just add this to your configuration on your config/environment.js file:

ENV['ember-qunit-nice-errors'] = {
  completeExistingMessages: true
};

Don't worry, the override will still show your orginal messages, it is not a destructive operation!

The following example ilustrates what is the result of using the option completeExistingMessages.

assert.ok(1 === 1, 'one should be one');

assert.ok(1 === 1, "assert.ok(1 === 1, 'one should be one')");

We are currently supporting all the assertions provided by QUnit, those are:

• ok
• notOk
• equal
• notEqual
• deepEqual
• notDeepEqual
• propEqual
• notPropEqual
• strictEqual
• notStrictEqual
