abstract class UpdatePathTestBase in Zircon Profile 8

Same name and namespace in other branches

8.0 core/modules/system/src/Tests/Update/UpdatePathTestBase.php \Drupal\system\Tests\Update\UpdatePathTestBase

Provides a base class for writing an update test.

To write an update test:

Write the hook_update_N() implementations that you are testing.
Create one or more database dump files, which will set the database to the "before updates" state. Normally, these will add some configuration data to the database, set up some tables/fields, etc.
Create a class that extends this class.
In your setUp() method, point the $this->databaseDumpFiles variable to the database dump files, and then call parent::setUp() to run the base setUp() method in this class.
In your test method, call $this->runUpdates() to run the necessary updates, and then use test assertions to verify that the result is what you expect.
In order to test both with a "bare" database dump as well as with a database dump filled with content, extend your update path test class with a new test class that overrides the bare database dump. Refer to UpdatePathTestBaseFilledTest for an example.
