On the surface, it may seem like code that uses Guzzle to make HTTP requests will be difficult, however thanks to Guzzle's handler and middleware APIs and Drupal's KernelTestBase, it's not that painful at all.
Jest is the defacto standard for testing in modern JavaScript, but until now, we haven't been able to leverage it for testing in Drupal. Thanks to twig-testing-library, that's changed.
Page objects are a pattern that can be used to write clearer and more resilient test suites. This blog post will explore implementing page objects in PHP with the Mink library.
Drupal allows writing tests for installation profiles. A profile can have sample content which is created during installation, like umami in Drupal core. Drupal allows writing tests for modules as well. A module can also have sample content which is created during installation or config import.
Drupal Testing Traits allows writing tests for an already installed site. A site with content types and content. You can write tests for the all the pages in your site in different viewports and test user interactions aka JavaScript tests.
In a recent project, we were outputting CSV and wanted to test that the file contents were valid.
Read on for a quick tip on how to achieve this with Drupal 10's BrowserTestBase
Last week I was fortunate enough to attend and deliver a session at DrupalCon Vienna. The session was based around leveraging and getting productive with the automated testing tools we use in the Drupal community.
Just a quick post to share a simple way to assert some markup is ordered correctly using BrowserTestBase
As you'd be aware by now - Drupal 8 features lots of refactoring of form procedural code to object-oriented.
One such refactoring was the way forms are build, validated and executed.
One cool side-effect of this is that you can now build and test a form with a single class.
Yep that's right, the form and the test are one and the same - read on to find out more.
PHPStorm has a lot of built in test runners, but it doesn't support Drupal's Simpletest test runner. In this blog post we'll see how we can execute Drupal tests inside PHPStorm using Drupal test runner.
