Testing

Cypress

End to end testing was added in this PR: https://github.com/guardian/manage-frontend/pull/790

Running Cypress tests via actions and locally

The steps to run these tests correctly are defined in the yml file: https://github.com/guardian/manage-frontend/blob/main/.github/workflows/cypress.yml

1. Run yarn cypress:server (this bypasses the Identity Gateway)
2. Run yarn cypress:open to test visually locally, or run yarn cypress:run to run tests with command line coverage

Cypress tips

• cy.getByText() fails if it can't find anything whereas cy.findByText() queries the DOM, but won't fail the test if nothing is found. Adding an extra function like .should('exist') is therefore necessary.
• Use cy.get('@api_call.all').should('have.length', 1); to determine how many times an endpoint was called during a test run.
