lasso ===== JavaScript widget and page unit testing with on the fly instrumentation [![NPM info][nodei.co]](https://npmjs.org/package/lasso-node) [![Build status][lasso-ci-image]][lasso-ci-url] [![dependencies][dependencies-image]][dependencies-url] [![devDependencies][devDependencies-image]][devDependencies-url] [![endorse][endorse-image]][endorse-url] installation ------------ npm install -g lasso-node Install phantomjs (version 1.8 or higher is recommended), it should be in the path. 30 second example ----------------- 1. Open examples\basic\foo.html in a browser. It should load foo.js, fooTests.js but report no coverage. 2. From command line run lasso on foo.html lasso-node foo.html Lasso starts a local webserver, starts phantomjs, runs the foo.html through the phantomjs. When phantomjs is asking for a .js file, lasso loads the js, instruments using *istanbul* and serves the instrumented version. Thus javascript code coverage is computed absolutely transparently to the testing code. After phantomjs is done, it saved the coverage object into a json file. Node then creates several reports: console and html. The html reports are very detailed, please take a look at them inside folder **cover**. Options ------- Use -h or --help command line switch to see all available options Main ones: + --jsunity - filters a few jsunity library js files to avoid instrumenting 3rd party tools + --serve - start the webserver and wait, you can then open http://localhost:8888/foo.html in any browser to see what phantomjs is running. Contact ------- Please contact me, Gleb Bahmutov at gleb.bahmutov@gmail.com with any comments, questions or suggestions. License ------- MIT license, see included file. You can do pretty much anything except claim code ownership or sue me if there are problems ;) [lasso-ci-image]: https://travis-ci.org/bahmutov/lasso.png?branch=master [lasso-ci-url]: https://travis-ci.org/bahmutov/lasso [nodei.co]: https://nodei.co/npm/lasso-node.png?downloads=true [dependencies-image]: https://david-dm.org/bahmutov/lasso.png [dependencies-url]: https://david-dm.org/bahmutov/lasso [devDependencies-image]: https://david-dm.org/bahmutov/lasso/dev-status.png [devDependencies-url]: https://david-dm.org/bahmutov/lasso#info=devDependencies [endorse-image]: https://api.coderwall.com/bahmutov/endorsecount.png [endorse-url]: https://coderwall.com/bahmutov
