Reduce build times by reusing the Postgres container between tests #2398

Closed timyates closed 1 month ago

Currently we start a Postgres container in TestContainerSuite

this container is not used by the tests as the TestPropertyProvider interface requires the test lifecycle to be Lifecycle.PER_CLASS (which this is not)
Instead all the test properties files specify a Test Containers URL and driver so each test starts a new container.

We can improve this situation by using the Micronaut test-resources plugin.

This will start a single postgres container which will be used by all the tests

A quick POC reduces the test time from almost 5 minutes to just over 2
