Click this button to generate a code coverage report and save it to the specified directory.

Every time Karma tests are run, a coverage report is actually generated on the disk. The format of a coverage report can be configured in the configuration file, for example:

// karma.conf.js module.exports = function(config) { config.set({ ... // optionally, configure the reporter coverageReporter: { type : 'html', dir : 'coverage/' } ... });};

The following type values are acceptable:

  • html produces a bunch of HTML files with annotated source code.

  • lcovonly produces an file.

  • lcov produces HTML + .lcov files. This format is applied by default.

  • cobertura produces a cobertura-coverage.xml file for easy Hudson integration.

  • text-summary produces a compact text summary of coverage, typically to the console.

  • text produces a detailed text table with coverage for all files.
