Hi @Patrick,
you can run the engine tests against a given database by yourself.
I’ve tried it with a simple postgresql in my Docker container, that contains the required tables already:
git clone https://github.com/camunda/camunda-bpm-platform.git
cd camunda-bpm-platform/engine
mvn clean test -Pdatabase,postgresql -Ddatabase.url=jdbc:postgresql:pgdb -Ddatabase.username=pguser -Ddatabase.password=pgpassword
The test run took about 01:44 h and ran 14637 tests.
If you provide the connection details from your Azure database, you can become confident, that the database technology will work with the Camunda engine (or not).
Hope this helps, Ingo
