👋 I was half expecting kotest to play nice with Junit5 extensions (such as Selenium-Jupiter) with at least AnnotationSpec but it doesn't appear kotest supports ParameterResolver (Junit docs). Am I understanding this correctly?

[sam]

No it's not compatible with junit rules. What are you trying to do as there might be a kotest way

[Matthew Wright]

I was trying to figure out if I could convert a JUnit annotation style test to use kotest and still use the Selenium-Jupiter extension with @ExtendWith (not old style JUnit4 rules). Here's the test in question. I assumed that if I used kotest's JUnit5 engine/runner that the extension would work with AnnotationSpec. I was able to get the engine/runner working and convert the test to look like so:

@ExtendWith(SeleniumJupiter::class)
class EmailAndPasswordRegistrationWorkflowSpec : AnnotationSpec() {

  @Test
  fun happyPath(driver: WebDriver) {
      ...
  }
}

But the driver: WebDriver parameter is not supplied and the runner/engine fails when trying to execute the test.

I know I could use testcontainers to manage webdriver containers, but browsers in containers aren't easy to work with when you want to run tests against something on localhost 😛

Yeah the ExtendWith isn't supported I'm afraid.

[Matthew Wright]

Gotcha. I figured as much but wanted to confirm.

[Matthew Wright]

I stumbled onto JunitExtensionAdapter. Any thoughts on if it could support the ParameterResolver extension?

[sam]

Yes in theory it should work, but it's not really tested fully yet.

@Matthew Wright Looks like you’re wanting to write a webdriver based test? did you consider FluentLenium? it provides a kotest integration

• example test

[Matthew Wright]

No! Hadn't seen this before. I'll check it out
