Server

This is the heart of the Cypress application. All of this code represents the node process running behind the browser application. This node process is responsible for:

  • Proxying every byte coming in and out of the browser
  • Performing and normalizing automation tasks for each browser
  • Coordinating and synchronizing state with the Desktop GUI and the Driver
  • Performing node specific tasks on behalf of the Driver
  • Instantiating and orchestrating nearly every other layer and package
  • Spinning up various static file and http servers
  • Communicating with our external API's
  • Recording videos of run
  • Managing mocha reporters
  • Managing 3rd party plugins

The Driver and the Server are the two most complex areas of the Cypress.

Install

The server's dependencies can be installed with:

cd packages/server
npm install

Development

To run Cypress:

npm start ## boots the entire Cypress application

Since the server controls nearly every aspect of Cypress, after making changes you'll need to manually restart Cypress.

Since this is slow, it's better to drive your development with tests.

Testing

  • npm run test-unit executes unit tests in test/unit
  • npm run test-integration executes integration tests in test/integration
  • npm run test-e2e executes the large (slow) end to end tests in test/e2e

Each of these tasks can run in "watch" mode by appending this word to the task:

npm run test-unit-watch

Because of the large number of dependencies of the server, it's much more performant to run a single individual test.

## runs only this one test file
npm run test ./test/unit/api_spec.coffee

You can also run in watch mode

## runs and watches only this one test file
npm run test-watch ./test/unit/api_spec.coffee
