This was just released. You try it out and see how updating can look. You write the Compose testing blog post that will be referenced for years to come. It's experimental tech at this point, there are no established patterns, unless you establish them.

Well there either is a way or their isn’t. My question is mostly wondering if something such as

androidx.ui:ui-test

exists for desktop. i.e.

class MyComposeTest {

    @get:Rule
    val composeTestRule = createAndroidComposeRule<MyActivity>()
    // createComposeRule() if you don't need access to the activityTestRule

    @Test
    fun MyTest() {
        // Start the app
        composeTestRule.setContent {
            MyAppTheme {
                MainScreen(uiState = exampleUiState, ...)
            }
        }

        onNodeWithText("Continue").performClick()

        onNodeWithText("Welcome").assertIsDisplayed()
    }
}

If you keep UI dumb and move all the logic out, you can test everything but UI with plain unit tests. The only thing left is to test the dumb UI, which is much less important in this case.

@Arkadii Ivanov There is no list module in the todo example.

Yeah, the

main

module

or maybe it’s possible to use a subset of the android testing library to actually test compose desktop
