Using flyway with play in test mode: Schema "public" not found

Question

I use (successfully) the flyway-play plugin in dev and prod mode. I also want to use it in test mode. The documentation says, it runs migrations automatically in test mode.

I use scala test and my testcases are wrapped in a fake application with

val fakeApplication = FakeApplication(additionalConfiguration = Map(
  "db.default.driver"->"org.h2.Driver",
  "db.default.url"->"jdbc:h2:mem:test;MODE=MySQL;DB_CLOSE_DELAY=-1;",
  "db.default.user"->"",
  "db.default.password"->""
))

When running test cases, the automigration fails with "Schema public not found":

What exactly does this error mean? Why is it using the public schema? My database config defines "db.default", not "db.public". What is the public schema? I didn't define it anywhere.

Any ideas on how I can make the test cases run (or at least get a step further)?

edit:

I found the hint ( Schema related problems with Flyway / Spring and H2 embedded database ) not to use MODE=MySQL in the h2 db url. Unfortunatelly I seem to need it for slick. If I don't use it, I get

So slick seems to use SQL commands not supported by H2 without MODE=MySQL (or am I wrong here?)

Using

"jdbc:h2:mem:test;MODE=MySQL;DB_CLOSE_DELAY=-1;INIT=CREATE SCHEMA IF NOT EXISTS \"public\"\\;"

results in the same error as if MODE=MySQL weren't present (so exactly the error shown in the box above)

Answer 1

Set flyway.schemas to PUBLIC (all caps) and you should be fine. (I hope :-) )

Answer 2

this line in application.properties work with or withor mysql mode

spring.datasource.url=jdbc:h2:mem:test;MODE=MYSQL;DB_CLOSE_ON_EXIT=FALSE;INIT=CREATE SCHEMA IF NOT EXISTS \"public\"\\;
