runEmptyComposeUiTest

@ExperimentalTestApi
fun runEmptyComposeUiTest(block: ComposeUiTest.() -> Unit): TestResult

Variant of runComposeUiTest that does not launch an Activity to host Compose content in and thus acts as an "empty shell". Use this if you need to have control over the timing and method of launching the Activity, for example when you want to launch it with a custom Intent, or if you have a complex test setup.

When using this method, calling ComposeUiTest.setContent will throw an IllegalStateException. Instead, you'll have to set the content in the Activity that you have launched yourself, either directly on the Activity or on an androidx.compose.ui.platform.AbstractComposeView. You will need to do this from within the test lambda, or the test framework will not be able to find the content.
