Failed to perform isDisplayed check

[braindonor]

Thanks for releasing this feature, I have been experimenting with Kakao and have successfully used it for Espresso and Espresso web views, and now I'm testing the Compose views. The app I'm testing contains all these components.

The problem I'm having is that I cannot get a testTag to match, even though it works fine with raw Compose [ like this: composeTestRule.onNode(androidx.compose.ui.test.hasTestTag(“MyStatusArea")).assertIsDisplayed() ]

I was hoping that you might spot some issue in my tree log. I'm a newbie to Compose, but have been successful in using the raw Compose functions.

Kind Regards,

Pentti

This is the Exception I get when using Kakao Compose:

java.lang.AssertionError: Failed to perform isDisplayed check.
Can't retrieve node at index '0' of '((isRoot).children).filter(TestTag = 'MyStatusArea')'
There are no existing nodes for that selector.

I've followed the sample and have this in my page object:

val statusArea = KNode(this) {
hasTestTag(“MyStatusArea")
}

And my test scenario contains:

onComposeScreen(composeTestRule) {
statusArea {
assertIsDisplayed()
}
}

I've logged the tree using this command:

composeTestRule.onRoot(useUnmergedTree = true).printToLog("COMPOSE_LOG")

Hello!

I have been running this issue aswell during the past days. It has something to do with the useUnmergedTree parameter that the onRoot should be able to receive. However the onRoot().onChildren() method doesn't take into account the nested children of the node no matter if you make use of useUnmergedTree or not.

I have opened a PR (#15) with a fix for it. Please take a look at it!
Thank you so much.

Hi @FrangSierra , I downloaded your branch and tested it against my project and it works great. I can't really comment on whether this is the best way to solve the problem as I'm not very familiar with the workings of compose.

Many thanks,

Pentti
