These are end to end tests triggered via a CI job. You can run these tests locally by following the instructions below, and they're automatically run as part of a CI workflow which runs when the packages/ or e2e-tests/ directory is changed in a commit.

• Create a folder e2e-tests/name-of-the-test
• Copy structure from an existing test, e.g. e2e-tests/path-prefix
• Add your tests in e2e-tests/name-of-the-test/cypress/integration/your-test-here.js

• cd to the test (e.g. cd e2e-tests/gatsby-image)
• Install dependencies: yarn or npm install
• OPTIONAL: Use gatsby-dev-cli to link current changes in packages
• Run the test script, e.g. yarn test or npm test
