Server
The server 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 driver packages
- 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 packages of Cypress.
Developing
To run the Cypress server:
## boots the entire Cypress application
yarn start
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.
Building
Note: you should not ever need to build the .js files manually. @packages/ts provides require-time transpilation when in development.
yarn workspace @packages/server build-prod
yarn test-unitexecutes unit tests intest/unityarn test-integrationexecutes integration tests intest/integrationyarn test-performanceexecutes performance tests intest/performanceyarn test-e2eexecutes the large (slow) end to end tests intest/e2e
You can also use the test-watch command to rerun a test file whenever there is a change:
yarn test-watch /test/path/to/spec.js
When running e2e tests, some test projects output verbose logs. To see them run the test with DEBUG=cypress:e2e environment variable.
Running individual unit tests
yarn test <path/to/test>
yarn test test/unit/api_spec.js
## or
yarn test-unit api_spec ## shorthand, uses globbing to find spec
Running individual integration tests
yarn test <path/to/test>
yarn test test/integration/cli_spec.js
## or
yarn test-integration cli_spec ## shorthand, uses globbing to find spec
Running individual e2e tests
yarn test <path/to/test>
yarn test test/e2e/1_async_timeouts_spec.js
## or
yarn test-e2e 1_async ## shorthand, uses globbing to find spec
To keep the browser open after a spec run (for easier debugging and iterating on specs), you can pass the --no-exit flag to the e2e test command. Live reloading due to spec changes should also work:
yarn test test/e2e/2_go_spec.js --browser chrome --no-exit
Updating snaphots
Prepend SNAPSHOT_UPDATE=1 to any test command. See snap-shot-it instructions for more info.
SNAPSHOT_UPDATE=1 yarn test test/unit/api_spec.js
SNAPSHOT_UPDATE=1 yarn test test/integration/cli_spec.js
SNAPSHOT_UPDATE=1 yarn test-e2e 1_async
