I m trying to add a simple unit test to my project I added ` kotlinlang #multiplatform

commonTest {
            dependencies {
                implementation kotlin('test-common')
                implementation kotlin('test-annotations-common')
            }
        }

And then in

commonTest/kotlin/

directory I have this file:

Copy code

class Test {

    @Test
    fun foo() {
        assertEquals(1,2,"Test failed")
    }
}

I run it

./gradlew :common:test

and I get errors like:

Copy code

> Task :common:compileDebugUnitTestKotlinAndroid FAILED
e: .../common/src/commonTest/kotlin/Test.kt: (1, 20): Unresolved reference: Test
e: .../common/src/commonTest/kotlin/Test.kt: (2, 20): Unresolved reference: assertEquals
e: .../common/src/commonTest/kotlin/Test.kt: (6, 5): 'Test' is not an annotation class
e: .../common/src/commonTest/kotlin/Test.kt: (8, 9): Unresolved reference: assertEquals

Not sure what is going on.

Are you missing imports for

Test

and

assertEquals

Also, make sure they’re not

org.junit.*

I have the imports and they're correct ones. IDE doesn't complain but it fails when I run the test

Here is a full source file:

Copy code

import kotlin.test.Test
import kotlin.test.assertEquals

class Test {

    @Test
    fun foo() {
        assertEquals(1,2,"Test failed")
    }
}

If I remove deps from build.gradle then IDE doesn’t see those classes as expected. Maybe the way I run the test is wrong?

Hmm the task that fails is

common:compileDebugUnitTestKotlinAndroid

🤔

this post mentions similar issue in

Executing tests

section: https://proandroiddev.com/current-issues-with-kotlin-multiplatform-and-how-to-fix-them-5ae62822a546

but I’m not using serialization

you need the correct imports for jvm/android

Copy code

implementation(kotlin("test"))
                implementation(kotlin("test-junit"))

the common APIs are just expect declarations
