How does it improve test reliability?

By mandating direct method invocation and prohibiting 'documentation-only' tests (tests without real assertions), it ensures that every test case actually verifies the intended behavior.

Why does the skill prohibit using line numbers in comments?

Line numbers are volatile and change as code evolves. The skill encourages describing logical conditions instead, making the test documentation more durable and easier to maintain.

How does it handle state interference between tests?

The skill enforces a 'State Reset' principle, requiring developers to reset render contexts and property groups before calling the target method to ensure a clean testing environment.

Does it support API verification?

Yes, it includes guidelines for using grep and read tools to verify exact method names and macro-generated properties within the ACE engine header files.

Seguridad y Pruebas

Implements rigorous Test-Driven Development patterns for OpenHarmony ArkUI NG component methods to ensure high code coverage and reliability.

This skill provides a specialized framework for writing unit tests within the OpenHarmony ArkUI ACE engine, specifically targeting NG component Pattern methods such as OnModifyDone and OnDirtyLayoutWrapperSwap. It guides developers through essential testing principles, including direct method invocation, mandatory state resets, and comprehensive branch coverage. By enforcing a strict self-checklist that eliminates magic numbers and documentation-only tests, this skill ensures that test suites are maintainable, logically sound, and physically decoupled from volatile source code line numbers.
