How do I run all the tests in a gradle multi-module project? So far, I need to run each module's tests seperately, I can't just run gradlew test...

[Tobi M.]

You should be able to run ./gradlew :<module-name>:test to just run the tests in one module.

[dave08]

Yeah, that's what I'm currently doing, but I need to run the whole suite in the CI, or after making major changes...

[sam]

just do ./gradlew check or /.gradlew test at the top level

[sam]

See kotest's own github actions files for an example

[dave08]

Tried, didn't work...

[sam]

what's the error

[dave08]

Test events not received

[sam]

sounds like you don't have the test task configured at your project root

[sam]

you can do that by adding the kotlin or java plugin to the build.gradle.kts for the root project

[dave08]

I have this at the root:

plugins {
    kotlin("jvm")
    kotlin("kapt")
    id("com.squareup.anvil")
}

[dave08]

And in Intellij's gradle toolbox, it exists under the root...

[Big Chungus]

Drop this in your root module

allprojects {
  afterEvaluate {
    tasks {
        if (tasks.findByName("test") == null) {
          register("test") {
            dependsOn(withType(KotlinTest::class))
            group = "verification"
        }
      }
    }
  }
}

[Big Chungus]

Then running ./gradlew test will run all tests in all modules, regardless if it's a jvm or mpp module

[sam]

That's only if you're using the kotest gradle plugin right ?

[dave08]

kotest gradle plugin?

[sam]

Oh never mind, I see, @Big Chungus means you don't need to use check task.

[sam]

This is the snippet I use to configure tests @dave08

tasks.named<Test>("jvmTest") {
   useJUnitPlatform()
   filter {
      isFailOnNoMatchingTests = false
   }
   testLogging {
      showExceptions = true
      showStandardStreams = true
      events = setOf(
         org.gradle.api.tasks.testing.logging.TestLogEvent.FAILED,
         org.gradle.api.tasks.testing.logging.TestLogEvent.PASSED
      )
      exceptionFormat = org.gradle.api.tasks.testing.logging.TestExceptionFormat.FULL
   }
}

[dave08]

KotlinTest::class

or

KoTest::class

?

And @sam, that does the same as what he posted?

[sam]

no, we're giving different options I think

[Big Chungus]

Yes, kotest != gradle

[Big Chungus]

So to get ./gradlew test to execute all your modules, use my suggestion above. I cannot comment on kotest plugin.

[dave08]

build.gradle.kts7823: Unresolved reference: findByName
...

[Big Chungus]

How's this

allprojects {
    afterEvaluate {
        tasks {
            if (findByName("test") == null) {
                register("test") {
                    dependsOn(withType(KotlinTest::class))
                    group = "verification"
                }
            }
        }
    }
}

[dave08]

@sam I copied this from hoplite:

tasks.named<Test>("test") {
    useJUnitPlatform()
    testLogging {
        showExceptions = true
        showStandardStreams = true
        exceptionFormat = FULL
    }
}

and some tests started running, there's a few compile errors now, but it seems like it's running. Thanks to both of you for pointing out the right direction!

[sam]

you were probably missing the useJUnitPlatform() at the top level then

[dave08]

A while passed since I tried this... I'm still having these problems. Only my domain module's tests are being run... I really wonder what could be wrong...?
