Composing Semantics Matchers

Agent skill
1 skill

Use this skill to build precise Compose UI test queries by composing SemanticsMatcher predicates with infix and, infix or, and operator not, plus the prebuilt filter library (hasText, hasClickAction, isEnabled, isOn, hasTestTag, hasContentDescription, hasParent, hasAnyAncestor, hasAnyChild, hasAnySibling, hasAnyDescendant, hasImeAction, hasScrollToKeyAction, hasScrollToNodeAction, isDialog, isPopup, isRoot, isFocused, isEditable, isHeading). Covers SemanticsMatcher.expectValue / keyIsDefined / keyNotDefined for custom semantics keys. Use when the developer asks how to find "an enabled button with text Submit", how to combine matchers, how to filter by a custom SemanticsPropertyKey, how to write a hierarchical predicate, or mentions hasParent, hasAnyAncestor, expectValue. If the developer wants one matcher instead of three chained assertions, use this skill.
