This can be used to find nodes in testing frameworks:
- In Compose's built-in unit test framework, use with [onNodeWithTag][androidx.compose.ui.test.onNodeWithTag].
- For newer AccessibilityNodeInfo-based integration test frameworks, it can be matched in the extras with key \"androidx.compose.ui.semantics.testTag\"
- For legacy AccessibilityNodeInfo-based integration tests, it's optionally exposed as the resource id if [testTagsAsResourceId] is true (for matching with 'By.res' in UIAutomator)."
