Tools for Unit Testing in Magento

Question

What do you use for Unit Testing in Magento? Or what do you know about Unit Testing and Magento? Whether you do TDD or you just want to have unit test coverage for your project components, you need some tools to do this.

The first basic approach is to use plain phpunit, but there are things that need additional gimmicks to make Magento "testable".

Everything I worked with is related to phpunit:

• MTAF
• EcomDev_PHPUnit (drawbacks: can't test emails)
• TechDivision_MagentoUnitTesting (attempt to backport Magento 2 Unit Tests)
• Mage-Test (lightweight unit testing for Magento)

Are there other options?

Answer 1

Check out PHPSpec with MageSpec if you want something not based on PHPUnit, but with some Magento Integration. Its usable, but not just quite ready for prime time. For mocking PHPSpec 2 uses Prophecy (which is great), but doesn't like magic getters and setters at all. For that reason its better to use Mockery instead, which works fine (and I also like it a lot).

Then there also is Behat with BehatMage for BDD with Magento. Worth a look, but it fails in for example if you want to test different store views on different domains.

There also is an extension to BehatMage called MageBehat (awful naming!), which came out of a hackathon. It provides a lot of Magento specific actions to BehatMage, but to be honest, some of the workarounds used are more of a hack then real solutions to the underlying issues. Still, its usable.

I hope to see both projects - MageSpec and BehatMage - flourish in future.

Answer 2

PHPUnit is what Magento 2 uses. Here is a sample file on GitHub. https://github.com/magento/magento2/blob/master/dev/tests/unit/testsuite/Magento/Captcha/Helper/DataTest.php. (I picked that file at random.) You might want to have a quick look at the Magento 2 test approach so that anything you do now is compatible with Magento 2 when released.

Answer 3

You should go with EcomDev PHPUnit.

I personally believe that all Magento developers should strive for a consistent unit testing solution. EcomDev provide the most commonly used and most mature of these frameworks so you already have a decent pool of developers with experience in it. Using a single framework also reduces the need to install a bajillion different frameworks.

EcomDev PHPUnit does have this odd convention of putting tests directly alongside the production code, however. Fortunately, this is easily addressed by modifying a few lines of code. EcomDev also take their sweet time with updates (although their Github repo shows signs of activity so they're clearly still alive).

Answer 4

For unit testing EcomDev PHPUnit is the best.

Maybe you want to try fonctionnal testing on Magento? Example with casperjs : https://github.com/jacquesbh/hackathon-casperjs/
