I am new to Kratos code, but am working on a PR. So the first step is to just see if I can run some unit tests. I did these steps from the docs:

make test-resetdb
export TEST_DATABASE_MYSQL='<mysql://root>:secret@(127.0.0.1:3444)/mysql?parseTime=true'
export TEST_DATABASE_POSTGRESQL='<postgres://postgres:secret@127.0.0.1:3445/kratos?sslmode=disable>'
export TEST_DATABASE_COCKROACHDB='<cockroach://root@127.0.0.1:3446/defaultdb?sslmode=disable>'

Then

cd selfservice/strategy/oidc
go test  -tags sqlite  .

I am getting this error:

Is there some step I am missing? I am also unclear on how to determine which tests are “short” tests and which aren’t. I get this error with both tags.

The error seems straightforward: are you running hydra?

I am not. Is that required to run unit tests?
