Testing

Single test run

• npm test (alternatively run karma start --single-run)
• npm run lint to run prettier

Tests during development

Start Karma to run tests after every change npm run test:watch.

Testing a production build locally

$ <kill your webpack-dev-server process>
$ npm run build
$ cd dist
$ python -m SimpleHTTPServer 1111
$ <go to http://localhost:1111 in the browser>

Debugging tests

1. option

• use console.log in the test and see the output in karma server output

2. option

• install karma-chrome-launcher npm module npm install karma-chrome-launcher --save-dev
• replace/add 'Chrome' to browsers in karma.conf.js
• now Karma will launch Chrome to run the tests
• use debugger; statement in test code to add breakpoints
• in Karma Chrome window click 'debug' button and debug in chrome developer tools as usual
• optionally you can use karma-jasmine-html-reporter for better test output
• make sure you don't push those changes to karma.conf.js and package.json as part of your patch
