Change function coverage to be backwards compatible (#356) There were 5 functions that were changed in a backwards incompatible way in #348: `createHitmap`, `mergeHitmaps`, `parseCoverage`, `toScriptCoverageJson`, and `Formatter.format`. This change makes #348 backwards compatible by renaming those newer functions, and adding versions of all those functions with the same signature as before. Most of these legacy functions simply wrap the newer versions and convert the `HitMap` back to a `Map<int, int>`. | Legacy | New | | --- | --- | | createHitmap | HitMap.parseJson | | mergeHitmaps | FileHitMaps.merge | | parseCoverage | HitMap.parseFiles | | toScriptCoverageJson | deprecated, no replacement | | Formatter | deprecated, no replacement | | PrettyPrintFormatter | FileHitMapsFormatter.prettyPrint | | LcovFormatter | FileHitMapsFormatter.formatLcov |
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.
// coverage:ignore-line to ignore one line.// coverage:ignore-start and // coverage:ignore-end to ignore range of lines inclusive.// coverage:ignore-file to ignore the whole file.
