Coverage

Coverage provides coverage data collection, manipulation, and formatting for Dart.

Tools

collect_coverage.dart collects coverage JSON from the Dart VM Observatory. format_coverage.dart formats JSON coverage data into either LCOV or pretty-printed format.

Collecting coverage from the VM

dart --enable-vm-service:NNNN --pin-isolates script.dart
dart bin/collect_coverage.dart --port=NNNN -o coverage.json --unpin-isolates

The --pin-isolates VM flag is used to prevent isolates from being cleaned up until coverage has been collected.

Collecting coverage from Dartium

dartium --remote-debugging-port=NNNN
# execute code in Dartium
dart bin/collect_coverage.dart --port=NNNN -o coverage.json

Formatting coverage data

dart bin/format_coverage.dart --package-root=app_package_root -i coverage.json

where app_package_root is the package-root of the code whose coverage is being collected. If --sdk-root is set, Dart SDK coverage will also be output.
