Skill instructions
Writing, Running, and Debugging Compiler Tests and Fourslash Tests This guide covers the complete testing workflow for the typescript-go repository, including compiler tests (type-checking, emit, diagnostics) and fourslash tests (language server features like completions, hover, go-to-definition). 1. Compiler Tests Compiler tests validate the TypeScript compiler's behavior: diagnostics, JavaScript emit, source maps, type/symbol baselines, and more. Each test is a .ts or .tsx file that the test runner compiles, then compares output against stored baselines. 1.1 Where Test Files Live | Path | Purpose | |------|---------| | testdata/tests/cases/compiler/ | Regression tests (local to this repo) | | testdata/tests/cases/conformance/ | Conformance tests (local to this repo) | | submodules/TypeScript/tests/cases/compiler/ | Submodule tests from upstream TypeScript | | submodules/TypeScript/tests/cases/conformance/ | Submodule conformance tests from upstream | 1.2 Writing a New Compiler Test A
