This is PrestaShop automated tests folder.

Multiple type of tests are available:

• UI folder contains user interface tests, see below

• Unit folder contains unit tests, see below

• Integration folder contains integration tests, see below

• Resources contains different resources need for some tests (code snippets, dummy modules, dummy themes, example files)

• TestCase contains some helper classes

This folder also contains a few scripts. They are used in our CI environment to trigger our different test campaigns.

PrestaShop end-to-end tests are powered by a tool suite as it requires:

• to control a browser behavior
• to mimic a user's behavior
• to setup a test case and validate the behavior

This folder contains our pages objects and our test code, organized in campaigns.

We use Mocha, Playwright and Chai as our base stack.

Please refer to our documentation.

PrestaShop unit tests are powered by phpunit.

• One php class = one test file.
• The test filepath must follow the class filepath/
• Every dependency of the class must be replaced by test doubles*.

*If there is a hard-coded dependency such as a singleton pattern being used or a static call, this class cannot be unit tested and should be tested using integration tests.

• Use camelCase names for test function names.
• Try to make method names explain the intent of the test case as best as possible. Don't hesitate to write long method names if necessary.
  • Bad example: testGetPrice (no idea what such a test is supposed to do)
  • Good example: testDiscountIsAppliedToFinalPrice

PrestaShop integration tests are powered by behat.
