Good morning everyone,
is https://documentation.spryker.com/v4/docs/t-testing-tdd-scos only for unit test or should it be possible to implement tests, that e.g. write to the database as well?

It is possible to implement integration tests and E2E tests with Spryker and Codeception. It's just not documented all too well (or at all, actually). Have a look at other tests in the test suite to get some examples.
The important part is switching out dependencies using the ContainerHelper in your Tester and using the TransactionHelpers.

The TransactionHelper seems like good start. But I get an “Unable to open connection” exception from Propel. Does it read the database credentials from the project or do I have to specify it again for the test suite somewhere?

Ok, running the tests inside the container does help. Thank you @UQ958DA4U

You need to make sure to run in the testing environment. So running docker/sdk testing ... is important here.

Look out though, after having gone into test mode, several things will have been switched off. You must use docker/sdk up again, to recreate Scheduler and a few other services.
