Run Dart SDK tests — language tests, corelib tests, analyzer tests, dart2js tests, and package-level tests. Use when running tests after building the SDK or verifying language changes.

Set up the Dart SDK development environment — from deps to full builds to running tests. Handles depot_tools, bootstrapping SDK, gclient sync, building, and test.py.
Build the Dart SDK compilers and VM runtime. Use when you need to compile the SDK, build specific targets (runtime, most, create_sdk, dart2js, analysis_server), or troubleshoot build issues.
Guide for modifying the Dart language — adding features, AST nodes, parser rules, CFE type inference, experimental flags, and diagnostics. Use when implementing or modifying Dart language features.

Official docs: docs/Testing.md
Build most and run_ffi_unit_tests before running tests:
bash .claude/skills/build-dart-sdk/scripts/build.sh most run_ffi_unit_tests
# Run VM language tests (most common)
bash .claude/skills/run-dart-tests/scripts/test.sh language
# Run a single test
bash .claude/skills/run-dart-tests/scripts/test.sh language/record_spreads/record_spread_test
# Run corelib tests
bash .claude/skills/run-dart-tests/scripts/test.sh corelib
# VM tests (default)
bash .claude/skills/run-dart-tests/scripts/test.sh language
# Analyzer tests
bash .claude/skills/run-dart-tests/scripts/test.sh --compiler dart2analyzer language
# dart2js tests
bash .claude/skills/run-dart-tests/scripts/test.sh --compiler dart2js --runtime chrome language
# DDC tests
bash .claude/skills/run-dart-tests/scripts/test.sh --compiler ddc --runtime chrome language
For pure-Dart packages under pkg/, use the bootstrapping SDK directly:
# Analyze a package
./tools/sdks/dart-sdk/bin/dart analyze pkg/front_end
# Run package tests
./tools/sdks/dart-sdk/bin/dart test pkg/analyzer
# Analyze with experiments enabled
./tools/sdks/dart-sdk/bin/dart analyze --enable-experiment=record-spreads pkg/front_end
| Suite | Directory | What it tests |
|---|---|---|
language | tests/language/ | Language feature tests (null-safe) |
corelib | tests/corelib/ | Core library tests |
lib | tests/lib/ | SDK library tests |
standalone | tests/standalone/ | Standalone VM tests |

After changing error messages or locations:
./tools/sdks/dart-sdk/bin/dart pkg/test_runner/tool/update_static_error_tests.dart -u "**/your_test.dart"
After changing parser behavior:
./tools/sdks/dart-sdk/bin/dart pkg/front_end/tool/update_expectations.dart
