I've made my first android app (a very simple button tapper) and am currently trying to create test files for it. I've been following the YouTuber Philipp Lackner and have gotten by pretty well despite most of his videos being a year or 2 out of date for the Android Studio (AS) version I'm using.
Being 2 years old now, the Unit Testing video of his chooses to not use JUnit5. I figured I'd give it a go due to how old the video was, but I've run into the following problem:
FAILURE: Build failed with an exception.
What went wrong:
Execution failed for task ':app:testDebugUnitTest'.
No tests found for given includes: [com.example..............sanityCheck](--tests filter)
My only test file so far:
package com.example.....
import com.google.common.truth.Truth.assertThat
import org.junit.jupiter.api.Test
class MainViewModelTest
{
@Test
fun sanityCheck()
{
val x = 0
assertThat(x).isEqualTo(0)
}
}

android section of the app gradle file:testOptions {
unitTests.all {
useJUnitPlatform()
}
}
I suspect this might be the solution to my problem, but useJUnitPlatform is seen as an unresolved reference. I don't know if I've missed something in my gradle file.
tasks.withType<Test> {
useJUnitPlatform()
}
Frankly, every time I see this as an answer to someone, the poster merely says to add it to the gradle file (without specifying further) despite there being 2 gradle files.

You have to apply the plugin:
id("de.mannodermaus.android-junit5") version "1.10.0.0"
Update your plugins block as:
plugins {
alias(libs.plugins.android.application)
alias(libs.plugins.jetbrains.kotlin.android)
alias(libs.plugins.com.google.devtools.ksp)
alias(libs.plugins.compose.compiler)
id("de.mannodermaus.android-junit5") version "1.10.0.0"
}
