oh-ut-generator

What problem does it solve?

This Skill eliminates the slow and error-prone process of writing OpenHarmony C++ unit tests by automatically generating HWTEST_F-compliant test code that matches existing patterns and branch logic.

Core Features & Use Cases

• OpenHarmony C++ UT generation: Produce comprehensive tests for normal, exception, and boundary scenarios using HWTEST_F conventions.
• Mocking that actually works: Generate and wire mock objects with proper EXPECT_CALL/ON_CALL usage so tests validate interactions instead of leaving mocks unused.
• Correct BUILD.gn integration: Align deps/include_dirs/external_deps/defines to the source code target configuration.
• Coverage and style guardrails: Enforce mandatory 75%+ coverage targets and maintain code style consistency with existing tests (>=70% consistency threshold).
• Special interface support: Handle NDK interfaces (OH_xxx) with create/destroy lifecycle pairing and NAPI functions (napi_xxx) with correct napi_* patterns, plus CJSON test patterns and memory management.

Quick Start

Use the oh-ut-generator skill to generate unit tests for the provided OpenHarmony C++ source file and return a complete HWTEST_F test file with matching BUILD.gn configuration.
