Cypress Angular Schematic

npm (scoped)

Add Cypress to an Angular CLI project

This schematic will:

  • install Cypress, it's dependencies, and new scripts
  • add necessary files for Cypress to work with Angular & Typescript
  • prompt for removal of Protractor files and configuration

Usage 🚀

Install globally

npm install -g @briebug/cypress-schematic

Then in an Angular CLI project run

ng g @briebug/cypress-schematic:add

Optionally run as one command in an Angular CLI app directory. Note this will add the schematic as a dependency to your project.

ng add @briebug/cypress-schematic

Thank You 🙏

Thanks to Kevin Schuchard for setting up the Schematic Sandbox, and writing the Jest schematic which inspired this schematic.

More info on this sandbox approach is detailed in this blog post kevinschuchard.com/blog/2018-11-20-schematic-sandbox/

Also, thank you to Zahid Mahmood for writing this blog post detailing setting up cypress in an Angular project.

Development 🛠

Getting started

Yarn is required for the scripts. Make sure it's installed on your machine.

Install the dependencies for the schematic and the sandbox application

yarn && cd sandbox && yarn && cd ..

🖇 Link the schematic in the sandbox to run locally

yarn link:schematic

🏃 Run the schematic

yarn build:clean:launch

To execute an example schematic, make sure you've ran the Install and Link steps above. Then run the following and inspect the changed files.

git checkout component-license && yarn build:clean:launch

E2E testing

Execute the schematic against the sandbox. Then run linting, unit & e2e tests and a prod build in the sandbox.

yarn test

Unit Testing

Run the unit tests using Jasmine as a runner and test framework.

yarn test:unit

Reset the sandbox

Running the schematic locally makes file system changes. The sandbox is version controlled so that viewing a diff of the changes is trivial. After the schematic has run locally, reset the sandbox with the following.

yarn clean

Note: if you're using the schematics CLI mentioned below, you can execute the schematic in a dry run mode.

Change the Schematic name

  1. do a global search and replace for schematic-starter and schematicStarter with the new name.
  2. change the folder name from ./src/schematic-starter/... to ./src/NEW_NAME/...
  3. run yarn link:schematic to set up local package linking for the sandbox

Optional - Testing with the Schematics CLI

To test locally, install @angular-devkit/schematics-cli globally and use the schematics command line tool. That tool acts the same as the generate command of the Angular CLI but also has a debug mode.

Check the documentation with

schematics --help

Publishing

To publish, simply do:

npm run build
npm publish
