Test that const decls are not marked coverable (#277) Constant declarations are evaluated during kernel compilation, not by the VM. This patch adds a const to `test_app_isolate.dart` and verifies that it doesn't appear in the coverage hitmap in `collect_coverage_test.dart` and `run_and_collect_test.dart`.
Coverage provides coverage data collection, manipulation, and formatting for Dart.
collect_coverage collects coverage JSON from the Dart VM Observatory. format_coverage formats JSON coverage data into either LCOV or pretty-printed format.
pub global activate coverage
Consider adding the pub global run executables directory to your path. See Running a script from your PATH for more details.
dart --pause-isolates-on-exit --disable-service-auth-codes --enable-vm-service=NNNN script.dart pub global run coverage:collect_coverage --uri=http://... -o coverage.json --resume-isolates
or if the pub global run executables are on your PATH,
collect_coverage --uri=http://... -o coverage.json --resume-isolates
where --uri specifies the Observatory URI emitted by the VM.
If collect_coverage is invoked before the script from which coverage is to be collected, it will wait until it detects a VM observatory to which it can connect. An optional --connect-timeout may be specified (in seconds). The --wait-paused flag may be enabled, causing collect_coverage to wait until all isolates are paused before collecting coverage.
pub global run coverage:format_coverage --packages=app_package/.packages -i coverage.json
or if the pub global run exectuables are on your PATH,
format_coverage --packages=app_package/.packages -i coverage.json
where app_package is the path to the package whose coverage is being collected. If --sdk-root is set, Dart SDK coverage will also be output.
