如何在Scala Slick中模拟数据库

Question

I am trying to mock db in a "Service" layer that is using Slick in order to Unit Test action composition in it.

Unfortunately I am not able to mock the db and JdbcProfile with Mockito. In particular I am not able to mock JdbcProfile#API in these lines of code:

  import driver.api._

  val dbConfig = databaseConfigProvider.get[JdbcProfile]

Do you know a better strategy to unit test Slick (I don't want to use Acolyte )?

Answer 1

have you considered mocking at a lower level?

personally I have a wrapper method that encapsulates the Database.forDataSource call. In my tests I spy that method to return a mock[Database] which I can use for all my persistence layer tests.
