Steps to reproduce the issue

  1. ./gradlew clean && ./gradlew runIdeForUiTests & ./gradlew test --tests "FullUiTest.verify requests and variables data"

What's the expected result?

  • IDE opens and UI tests start running

What's the actual result?

  1. The error occurs
  2. IDE opens
  3. UI test does not run

Additional details / screenshot

Test class (RemoteRobotExtension and welcomeFrame copied from this repo's sample dir)

@ExtendWith(RemoteRobotExtension::class)
class FullUiTest {

    @Test
    fun `verify requests and variables data`(remoteRobot: RemoteRobot): Unit = with(remoteRobot) {
        welcomeFrame { createNewProjectLink.click() }

The test runs if I run the syntaxes separately:

  1. Terminal 1: ./gradlew clean && ./gradlew runIdeForUiTests
  2. Wait for IDE's welcome screen
  3. Terminal 2: ./gradlew test --tests "FullUiTest.verify requests and variables data"
commented

Hi, thanks for the issue. Seems that test can't reach Idea because it is not started yet. I've added @BeforeEach method which waits for the Ide. Can you check if it works for you?

commented

New IDE is opened before test starts but test is timing out in the @BeforeAll code. Here's link to the test

Thanks for the example, I've tried and got this

FullUiTest > verify requests and variables data(RemoteRobot) FAILED
    java.lang.NoClassDefFoundError at FullUiTest.kt:43
        Caused by: java.lang.ClassNotFoundException at FullUiTest.kt:43

So, I think the cause is in simultaneously running test and clean tasks, clean just interfere and brakes tests.

./gradlew runIdeForUiTests & ./gradlew test --tests "FullUiTest.verify requests and variables data"
commented

I tried the full command again (with clean) and it's working: ./gradlew clean && ./gradlew runIdeForUiTests & ./gradlew test --tests "FullUiTest.verify requests and variables data"

waitForIgnoringError(ofMinutes(3)) { remoteRobot.callJs("true") } has resolved the issue. Thanks.
