How do I use the SystemEnvironmentProjectListener (or really any externally defined project listener) in my project?

I found a README that says to do this:

class ProjectConfig : AbstractProjectConfig() {

    override fun listeners(): List<TestListener> = listOf(SystemEnvironmentProjectListener("foo", "bar"))

}

but AbstractProjectConfig::listeners is deprecated and the deprecation message, “`Use extensions."` , isn’t the most helpful. I would like to define the listener once for the whole project.

Try this:

object EnvironmentExtension : TestCaseExtension {
   override suspend fun intercept(testCase: TestCase, execute: suspend (TestCase) -> TestResult): TestResult {
      return withEnvironment("" to "") {
         execute(testCase)
      }
   }
}

object ProjectConfig : AbstractProjectConfig() {
   override fun extensions() = listOf(EnvironmentExtension)
}

I can try updating the readme if it works. Perhaps we could also raise an issue about creating a replacement for SystemEnvironmentProjectListener

Lol, I didn’t even realize extensions was a function in AbstractProjectConfig . I thought when the message said “extensions” it was talking about extensions in the abstract 😅

It looks like a Listener is an Extension so this might just work, trying now…

Ah, convenient 🙂
