João Boto commented on FLINK-30790:
-----------------------------------
h3. Refactor parametrised class with multiple containers
This should reduce the time to start this classes, spreading the time for
multiple classes.. This change will have little effect, but is important to
improve latter the time and number of times container will be created.
Will allow to define basic extension rules to tests that we want on all
implemented databases.

> The main problems that we see on testings are:
> * Parameterized tests that setup database containers (this tends to be more
> time consuming as another databases are added)
> * Creation of containers by class (this is fine as we want test to be
> independents, but the database could be setup 1time and cleaned at end of
> each class)
> * No easy way to extend a test to another database, at the end we copy a lot
> of code
> * A lot of code for create and populate tables for testing. We have
> JdbcTestBase that use JdbcTestFixture to create a kind of 'Book Store', but
> this is used in a lot of test without the use of all tables that are
> implemented on store.
