I like how I am able to jump to a method when using JUnit's MethodSource, is there a way to define the same behaviour for a custom annotation, also requiring a method name?

it's built into the JUnit plugin: https://github.com/JetBrains/intellij-community/blob/master/plugins/junit/src/com/intellij/execution/junit/references/JUnitReferenceContributor.kt

Dont think the issue is necessary, this is built into IDE as language injection. Inject language on your annotation string parameter and use method reference

[robstoll]

can you point me to something how

Inject language on your annotation string parameter and use method reference

can be done?

[ephemient]

I assume they mean something like

annotation class MySource(
    @Language("java")
    val method: String,
)

@MySource("com.example.Something::somehow")

[ephemient]

but in any case, the IDE integration isn't a JUnit issue

[efemoney]

internal annotation class InternalMediaApi(
  @Language("jvm-method-name") val string: String = ""
)

[ephemient]

if you want it to work a specific different way, you can write your own intellij plugin

nice, glad I asked, the @Language annotation solved my issue nicely 🙂
