library1.0.2jsnpmunverified

Code coverage addon for Ember apps using Istanbul. Current version 1.0.2 (last release). Works with any transpiler. Supports Mocha, Mirage, Pretender. Configurable via ember-cli-build.js. Key differentiators: uses Istanbul instead of Blanket, instruments code during build, parallel testing support via ember-exam, and passthrough for Ajax interception. Requires Testem >=1.6.0 for Mocha, and appropriate versions of Mirage/Pretender.

Configuration is done via ember-cli-build.js, not via imports. The addon is used through environment variable COVERAGE.

Shows install, config, and usage of ember-cli-nacho-coverage with environment variable.

// Step 1: Install the addon // ember install ember-cli-nacho-coverage // Step 2: Configure in ember-cli-build.js (optional) module.exports = { coverageEnvVar: 'COVERAGE', reporters: ['lcov', 'html'], excludes: ['*/mirage/**/*'], coverageFolder: 'coverage', parallel: false }; // Step 3: Run tests with coverage enabled // COVERAGE=true ember test // For parallel testing: // ember exam --parallel // ember coverage-merge

Known issues
gotchaWhen using Mirage or Pretender, you must set up a passthrough for /write-coverage. The passthrough must appear before the namespace setup in Mirage config.
fix
In mirage/config.js: this.passthrough('/write-coverage'); before setting namespace.
affects: >=0.0.0
gotchaIf using Mocha, Testem must be >=1.6.0 and ember-cli >2.4.3.
fix
Upgrade Testem and ember-cli as needed.
affects: >=0.0.0
gotchaThe json-summary reporter is always added regardless of configuration. Do not remove it.
fix
Just include other reporters; json-summary is automatic.
affects: >=0.0.0
gotchaParallel testing requires using ember coverage-merge after tests to combine reports.
fix
Run 'ember coverage-merge' after parallel tests.
affects: >=0.0.0
