I'm trying to set up some unit tests which need to load a fixture file
every time. Unfortunately I get an "SQLSTATE[23000]: Integrity
constraint violation: 1451 Cannot delete or update a parent row: a
foreign key constraint fails" error (also when using "symfony
doctrine:data-load") .

I guess doctrine tries to delete data with "onDelete: RESTRICT"
relations too early, i.e. not in the order inserted. Changing to
"onDelete: CASCADE" would surely solve the problem but destroys my
database concept.

This is very annoying since i cannot use unit tests this way. Also, to
load changed fixture files for testing purposes in the browser i
ALWAYS have to drop the whole database.

I followed the steps from Day 8 of the Jobeet tutorial, but there
onDelete: CASCADE is used.

Is there any other way to solve this as writing an own data deletion
script which i have to execute every time?
