android-junit5 | Testing with JUnit 5 for Android | Plugin library

I wanted to configure Jetpack Compose. I did it and but during running the app I get that error everytime. Jetpack is in the project and I can use it but I can't run the app.

Execution failed for task ':myModule:prepareDebugKotlinCompileTask'.

Could not resolve all files for configuration ':myModule:kotlin-extension'. Could not find androidx.compose:compose-compiler:1.0.0-alpha05. Searched in the following locations: - https://dl.google.com/dl/android/maven2/androidx/compose/compose-compiler/1.0.0-alpha05/compose-compiler-1.0.0-alpha05.pom

My module's Gradle file:

Convert a standard JUnit 5 test into a parameterized test in order to iterate through a stream of test cases using the @ParamterizedTest and @MethodSource annotations in Kotlin.

The @MethodSource is unable to access the stream of data. This seems to be an issue with this annotation specifically, as @ValueSource(strings = ["SF", "NYC"]) iterates through the statically defined options as expected.

Error:

PreconditionViolationException: Cannot invoke non-static method {someMethodName} on a null target.

The parameterized test is set to pass in a stream of data classes similar to the setup outlined by Phillip Hauer in Data Classes for Parameterized Tests.

build.gradle (:SomeProject)

Using a JUnit 5 local unit test, run a Room database @Insert and Query within a TestCoroutineDispatcher().

The Room database @Insert and @Query is executed within TestCoroutineDispatcher().runBlockingTest, causing the error below. The database calls will work if the threading is explicitly defined with the non-test dispatcher, Dispatchers.IO.

Error log:

Cannot access database on the main thread since it may potentially lock the UI for a long period of time.
