Testing - Using Postgres in Prod, but H2 in Test

[Kevin Meredith]

I'm trying to set up in-memory integration tests for my Slick 3 DB services.

I saw https://www.typesafe.com/activator/template/slick-testkit-example-3.0. However, I'm accessing Postgres in my prod code, but H2 in test.

Are there any examples on how to perform such testing?

Hi Kevin,

To abstract over the database you can use different configuration files for test and prod. Use Database.forConfig to get back a DatabaseConfig, which holds a database and a driver. Then, it will be usual Slick code from there.

Cheers,

Mirco

Hello,

Mirco's answer is logical, but just like you, I have trouble to figure out the pattern to inject Postgres for production and "override" it with h2 for test ... have you found out? Do you have an example to help me?

Thanks
