Istanbul code coverage loader for Webpack
This is a Webpack loader that uses Istanbul to add code coverage instrumentation to your code. This is especially useful for in-browser testing, in a tool like Karma, where you can use karma-coverage-istanbul-reporter to output code coverage data in a variety of formats that are supported by services like Coveralls or Codacy.
Coverage Istanbul Loader is based on Istanbul Instrumenter Loader, but uses a newer version of the Istanbul API and has better support for source maps.
Usage
See the examples folder for usage examples for various use cases.
-
"hello, world" example<br> This is the most simplistic example. It just uses coverage-istanbul-loader with its default options to produce an output bundle that contains code coverage instrumentation.
-
TypeScript example<br> This example demonstrates using coverage-istanbul-loader with transpiled code. It correctly maps the instrumented JavaScript code back to the original TypeScript source code.
-
Karma example<br> This example demonstrates using coverage-istanbul-loader with Karma and karma-coverage-istanbul-reporter to produce code coverage reports for browser tests.
-
Example with options<br> This example demonstrates passing options to coverage-istanbul-loader. The options are passed-on to istanbul-lib-instrument, so all the same options are supported.
