Hide successful QUnit tests

Published 03 Jun 2010

I am now using QUnit as TDD framework for my JavaScript development. It’s not as sophisticated as NUnit is for .NET or SimpleTest for PHP, but it’s reaaally easy to get started with.

However, QUnit strange enough QUnit lists all tests after a test run, not just the ones that fails. With just a few executing tests, the report looks like this:

QUnit - Full test report

As you can see, QUnit lists all executed tests by default, even the ones that is successfully executed.

The test suite above only includes 14 tests. Imagine having a hundred unit tests or so! In my opinion, this way of presenting the test result hides the essential outcome of the test suite – to discover tests that fail.

I get that one should be able to see that all tests are executed, but the number of executed tests are listed in the result footer. Why would I need to see every successful tests? Show me the ones that fail.

If anyone knows a built-in way to achieve this, please let me know. I chose this following approach (applies to jQuery 1.4.2 – let me know if this is out-of date):

  • Open the qunit.js file
  • Find the block that begins with var li = document.createElement("li");
  • Wrap the entire block in if (bad) { ... }

This will make QUnit only append the list element if a test is “bad”, that is if it failed. The result will look like this:

QUnit - Compact test result presentation

Maybe there is a built-in way of making QUnit behave like this. If you know how, please leave a comment.
