Cypress Setup for WordPress

NPM package to set up boilerplate for Cypress testing.

Usage

The script will do everything required: install dependencies, add scripts to your package.json and create some files required to run Cypress and wp-env.

# Go to your project folder
cd ~/my-plugin

# (Optional) Initialize NPM if not yet
npm init

# Run the boilerplate script
npx github:10up/cypress-wp-setup

Now you are able to manage wp-env and run Cypress tests.

Command-line tools

WordPress environment

Always use this command to start the environment in GitHub Actions because it will apply the fix to make permalinks working.

npm run env:start

This is a shortcut to wp-env:

npm run env

Set WordPress version

./tests/bin/set-core-version.js <version>

<version> might be:

• latest to use current WordPress release
• master to use nightly build
• 5.9 to specify a version

Numeric version should match existing tags in WordPress repository.

Cypress

# Run tests
npm run cypress:run

# Or open debug Chromium
npm run cypress:open

Cypress commands

The boilerplate includes a single basic example test.

The setup includes Cypress WP Utils library with a set of Cypress commands designed to write tests for WordPress.

cy.login();

cy.activatePlugin("my-plugin");

cy.createPost({
  title: "Post Title",
  content: 'Test Content',
});

GitHub Actions workflow

The distribution includes the config for GitHub Actions in .github/workflows/cypress.yml. It will install dependencies, run wp-env, and perform tests.

You can specify WordPress versions to test against in the matrix:

strategy:
  matrix:
    core:
      - {name: 'WP latest', version: 'latest'}
      - {name: 'WP minimum', version: 'WordPress/WordPress#5.2'}
      - {name: 'WP trunk', version: 'WordPress/WordPress#master'}

The job includes 2 optional steps, you can update them and make required (removing continue-on-error flag):

- name: Composer (optional)
  run: composer install
  continue-on-error: true
- name: Build (optional)
  run: npm run build
  continue-on-error: true
