Coverage Tool Window

View | Tool Windows | Coverage

This tool window appears on running JSTestDriver tests with coverage or Karma tests with coverage, and displays coverage measurement results.

In this section:


arrowUpClick this button to go up one level.
autoScrollToSource When this button is pressed, source code of the class selected in the tool window, automatically opens in a separate editor tab, and gains the focus.
autoscrollFromSource When this button is pressed, when source code of certain class gets the focus in the editor, the corresponding node is automatically highlighted in the tool window.
exportToTextFile Click this button to generate a code coverage report and save it to the specified directory.

The button is not available when the tests are executed on Karma because a coverage report is actually generated on the disk every time Karma tests are run. 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 lcov.info 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.
