What are you trying to achieve?

We have a bug test suite which takes a lot of time to finish.
There are some tests that depend on each other (e.g. a test for creating an entity requires another test to register a user and verify a new user)

As the hole test suite takes a lot of time I want to run a specific test only (e.g. creating an entity) but everything I tried results in failure as the depend tests don't get executed.

In general Codeception is configured to run everything on ./vendor/bin/codecept run.
So to run only specific SpotStatsBuildCest which depends on others I tried the following:

Try 1:
./vendor/bin/codecept run SpotStatsBuildCest

Suite 'SpotStatsBuildCest' could not be found

Try 2:
./vendor/bin/codecept run --fail-fast ./test/integration/cest/SpotStatsBuildCest.php

Integration Tests (3) --------------------
S SpotStatsBuildCest: Run peak calculation job 
S SpotStatsBuildCest: Send peak success calculation notification mail 
S SpotStatsBuildCest: Send peak failed calculation notification mail 
---------------------------------------------------------------------

Try 3:
Added a @group SpotStatsBuildCest to the class and
./vendor/bin/codecept run --fail-fast --group SpotStatsBuildCest

[Groups] SpotStatsBuildCest

Integration Tests (3) --------------------
S SpotStatsBuildCest: Run peak calculation job 
S SpotStatsBuildCest: Send peak success calculation notification mail 
S SpotStatsBuildCest: Send peak failed calculation notification mail 
---------------------------------------------------------------------

How can I run only this specific cest (+ dependencies)?
