Once all modifications are done your tests should looks like

  @Test
    fun search_compose_in_view() {
        Log.time("Compose in View") {
            withId(R.id.compose_in_view)
                .getView()
                .getSemanticsNodeInteraction(matcher = hasText(composeInViewTag))
                .assertIsDisplayed()
        }

    }

    @Test
    fun search_view_in_compose() {
        Log.time("View in Compose") {
            withId(R.id.view_in_compose)
                .getView()
                .getSemanticsNodeInteraction(matcher = hasTestTag(viewInComposeTag))
                .onView()
                .hasText(viewInComposeTag)
                .isDisplayed()
        }
    }
    ```

here , we can avoid onView and just call withId(R.id.compose_in_view).getView()

[alex-tiurin]

the same withId(R.id. view_in_compose).getView()

Please, take a look at this part of documentation. (https://open-tool.github.io/ultron/docs/common/extension#customize-operation-info)
To make new Ultron library method we need to follow few rules:

1. The action/assertion should pass throw the Ultron core logic. So, you need to call special method for this.
2. we also need to put action logic to the extension function of UltronComposeSemanticsNodeInteraction class.
3. It should has proper description for external library users

Smth like this:

@OptIn(InternalComposeUiApi::class)
fun UltronComposeSemanticsNodeInteraction.fetchView(): View? = execute(
    UltronComposeOperationParams(
        operationName = "Fetch Android interop view of '${semanticsNodeInteraction.getSelectorDescription()}'",
        operationDescription = "Compose fetch Android interop view of '${semanticsNodeInteraction.getSelectorDescription()}' during $timeoutMs ms",
        operationType = ComposeOperationType.FETCH_INTEROP_VIEW
    )
) {
    ((it.fetchSemanticsNode()
        .layoutInfo as? InteroperableComposeUiNode)?.getInteropView())
}

Extend com.atiurin.ultron.core.compose.operation.ComposeOperationType with new enum values FETCH_INTEROP_VIEW, ON_INTEROP_VIEW

[alex-tiurin]

We don't interact with SemanticsNodeInteraction directly, so this method should be deleted

[alex-tiurin]

we also need to move fetch logic to ultron core

@OptIn(InternalComposeUiApi::class)
fun UltronComposeSemanticsNodeInteraction.onView(): Matcher<View> = execute(
    UltronComposeOperationParams(
        operationName = "Fetch and wrap Android interop view of '${semanticsNodeInteraction.getSelectorDescription()}' with Mather<View>",
        operationDescription = "Compose fetch and wrap Android interop view of '${semanticsNodeInteraction.getSelectorDescription()}' with Mather<View> during $timeoutMs ms",
        operationType = ComposeOperationType.ON_INTEROP_VIEW
    )
) {
    AndroidViewMatcher(
        (semanticsNodeInteraction
            .fetchSemanticsNode().layoutInfo as? InteroperableComposeUiNode)
            ?.getInteropView()
    )
}

[alex-tiurin]

delete this method

[alex-tiurin]

lets rename this method to getSemanticsNodeInteraction and return ultron wrapper

@OptIn(InternalTestApi::class)
fun View.getSemanticsNodeInteraction(
    matcher: SemanticsMatcher,
    useUnmergedTree: Boolean = true
): UltronComposeSemanticsNodeInteraction {
    val composeView = requireNotNull(this as? AbstractComposeView) { "View is not subtype of AbstractComposeView. It is ${this::class.java}" }
    return UltronComposeSemanticsNodeInteraction(SemanticsNodeInteraction(
        createTestContext(ViewAndroidTestOwner(composeView)),
        useUnmergedTree,
        matcher
    ))
}

In general, this is a great PR. Thanks a lot for your time. Appreciate that
