Runner

The runner is the minimal "chrome" around the user's app and has the following responsibilities:

• Managing communication between the driver, the reporter, the extension, and the server
• Managing the viewport size and scale
• Showing the currently active URL

This package also includes the majority of the code that gets injected into the App Under Test (AUT) by packages/proxy. That bundle's entry point is injection/index.js.

Developing

Watching

This watches and compiles all changes as you make them.

• Runs *.js and *.jsx through babel and bundles with browserify into single dist/cypress_runner.js
• Runs associated unit test of file saved and outputs to terminal
• Compiles *.scss files to single dist/cypress_runner.css
• Additionally it compiles both the reporter and driver
