Composing With Confidence
summary
Shows how to test Jetpack Compose UIs end-to-end and component-level using concrete code: use createComposeRule or createAndroidComposeRule to render composables, find nodes with onNodeWithText/Tag, assert enabled/displayed/text and call performClick or performTextInput. Demonstrates a real button test (click flips a Boolean when enabled), inspects a rendered match card by printing the node tree to verify inline "[winner]" becomes a trophy icon, and compares pixel snapshots with Paparazzi. Recommends reusable login screen robot helpers to reduce duplicated selectors and keep flow tests readable.
