Equivalent of api for test dependency in gradle?

Question

I'm having multi module gradle project. In one of my modules I'm having api dependency:

api('de.flapdoodle.embed:de.flapdoodle.embed.mongo')

I want to change it to dependency that will be visible in tests, across all modules. There is a testImplementation dependency but there is no testApi.

I cannot have this dependency on production classpath anymore since I want to use real mongo instance instead of embedded one. On the other hand I have tests in different modules that depend on data access - in that case I want to run those test with embedded mongo on test classpath.

How I can make this dependency visible in all modules tests?

Answer 1

The question (appears to me) is sharing the test code across modules in a multi-module project

Short answer - No - there is direct test dependency share across modules.

To share test code between modules internally via build settings

Official gradle route https://docs.gradle.org/current/userguide/java_testing.html#sec:java_test_fixtures

Simple hack

testImplementation files(project(':core-module').sourceSets.test.output.classesDirs)

add the above line either individually where you need or in root with subprojects() with appropriate condition

*there are other possible routes as well *
ex: via configuration child.testImplementation extends parent.testImplementation (or runtime)
