CLI

The CLI is used to build the cypress npm module to be run within a terminal.

The CLI has the following responsibilities:

  • Allow users to print CLI commands
  • Allow users to install the Cypress executable
  • Allow users to print their current Cypress version
  • Allow users to run Cypress tests from the terminal
  • Allow users to open Cypress in the interactive Test Runner.
  • Allow users to verify that Cypress is installed correctly and executable
  • Allow users to manages the Cypress binary cache
  • Allow users to pass in options that change way tests are ran or recorded (browsers used, specfiles ran, grouping, parallelization)

Building

See scripts/build.js. Note that the built npm package will include NPM_README.md as its public README file.

Testing

Automated

From the repo's root, you can run unit tests with:

yarn test-unit --scope cypress
yarn test-watch --scope cypress
yarn test-debug --scope cypress

Updating snaphots

Prepend SNAPSHOT_UPDATE=1 to any test command. See snap-shot-it instructions for more info.

SNAPSHOT_UPDATE=1 yarn test-unit --scope cypress

Type Linting

When testing with dtslint, you may need to remove existing typescript installations before running the type linter (for instance, on OS X, you might rm -rf ~/.dts/typescript-installs) in order to reproduce issues with new versions of typescript (i.e., @next).

Manual

To build and test an NPM package:

  • yarn
  • yarn build

This creates build folder.

  • cd build; yarn pack

This creates an archive, usually named cypress-v<version>.tgz. You can install this archive from other projects, but because there is no corresponding binary yet (probably), skip binary download. For example from inside cypress-example-kitchensink folder

yarn add ~/{your-dirs}/cypress/cli/build/cypress-3.3.1.tgz --ignore-scripts

Which installs the tgz file we have just built from folder Users/jane-lane/{your-dirs}/cypress/cli/build.
