Using test helpers

Edit on GitHub

Codeception provides so-called modules, which are helpers used for building your tests. These helpers allow you to hook into the lifecycle of tests and get handy methods available wherever the helper is enabled. Codeception and Spryker provide a lot of ready to use helpers. Checkout Available Test Helpers for information on some of them.

Basically, almost every Spryker module provides one or more helpers. The helpers can be found in the tests/Organization/Application/Module/_support/Helper/* directory. For example, check out the helper of the Router module.

Enabling a helper

To make a helper available for your tests, you need to enable it in the codeception.yml configuration file.



        path: path/to/tests
        actor: Module{Layer}Tester
                - \SprykerTest\Shared\Testify\Helper\ConfigHelper

This will enable the \SprykerTest\Shared\Testify\Helper\ConfigHelper in your tests.

For a real example, check out the codeception.yml file of the Router module.

Test lifecycle

Helpers give easy access to every point of the test lifecycle. A test lifecycle looks as follows:

  • Before test suite
    • Before test
      • test
    • After test
    • Before test
      • test
    • After test
  • After test suite

With the helpers, you can hook into every point of this lifecycle and do things that are required for your test case. For example, create an application state before the test itself has been executed, or clean up after the test has been executed, etc.

Checkout the Codeception helper, the Hooks section, for information about each method of the Codeception’s module class.

Helper methods

When you have code blocks that are re-usable in other modules as well, consider creating a helper with a method that provides the re-usable code.

Every public method in your helper will be generated into the tester class, and can be executed from within your test after you run vendor/bin/codecept build.

In your test, you can use the public methods with:


Creating your own helper

It is very easy to create your own re-usable helper - you just need to create one in your test suite. For example:

namespace OrganizationTest\Module\Application\Helper;

use Codeception\Module;
use Codeception\TestInterface;

class MyHelper extends Module
      * @param \Codeception\TestInterface $test
      * @return void
    public function _before(TestInterface $test): void

    public function doSomethind()

This helper adds one method you can use in your test class and executes the _before method before each test is executed. You now only need to enable this helper in your codeception.yml.

There are almost endless things you can put into these helper classes. For more information, see Codeception modules and helpers documentation.

Using another helper in a helper

To get easy access to other helpers, for most of the helpers, Spryker provides a trait that can be used in your helper to get access to it.

If your helper needs access, for example, to ConfigHelper of the Testify module, just add the trait to your helper:

class YourHelper extends Module
    use ConfigHelperTrait;

    public function yourHelperMethod()
