How do you test a Compose click and verify state change?
This tests Compose semantics and interaction-to-assertion flow. Mention ComposeTestRule, onNodeWithTag, performClick, and assert on the changed node with assertIsDisplayed or assertTextEquals.
This question tests whether you understand Compose semantics testing and the correct interaction-to-assertion pattern. A strong answer starts with creating a ComposeTestRule, then uses onNodeWithTag to locate the target composable, performClick to fire the interaction, and finally asserts on the affected node using matchers like assertIsDisplayed or assertTextEquals. You should also mention that testTag must be applied via Modifier.testTag in the production code for the node to be discoverable.
