What is the best way to use a common module containing mocks, which is then included in other test modules?

[lukisk]

I would like to create a module where I put mocks into the common source sets, and then I would include this module as a project in the commonTest source sets. Is there any way to use Mokkery in common source sets?

Hello! Yes, this is possible. Here's how you can do it:

1. Apply Mokkery to the subproject containing mocks.
   You’ll need to adjust the default application rule so Mokkery is applied to all sources in the subproject:

mokkery {
    rule.set(ApplicationRule.All)
}

2. Add the mocks module as a dependency in subprojects of your choice.

dependencies {
    commonTestImplementation(project(":mocks-module"))
}

3. If you want to use Mokkery API (e.g. every or verify) in the other subprojects, make sure to also apply Mokkery there as needed.
