Version 0.13.3+2 (#279)

Tighten the dependency on the `vm_service` package from `>=1.0.0 <3.0.0`
down to `>=1.0.0 <2.1.2` in order to exclude version `2.1.2` which is
broken on the current stable Dart VM due to a missing SDK constraint in
its pubspec.yaml. The breakage was introduced in:
https://github.com/dart-lang/sdk/commit/9e636b5ab4de850fb19bc262e0686fdf14bfbfc0.

Coverage

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

Build Status Coverage Status Pub

Tools

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

Install coverage

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.

Collecting coverage from the VM

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.

Formatting coverage data

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.
