Run Dart SDK Tests

Official docs: docs/Testing.md

Prerequisites

Build most and run_ffi_unit_tests before running tests:

bash .claude/skills/build-dart-sdk/scripts/build.sh most run_ffi_unit_tests

Quick test

# 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

Test configurations

# 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

Package-level tests

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

Test suites

Update static error test expectations

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"

Update parser test expectations

After changing parser behavior:

./tools/sdks/dart-sdk/bin/dart pkg/front_end/tool/update_expectations.dart
