Opal Frontend Cypress Component Testing

Overview

Use these rules when writing or updating Cypress component specs in opal-frontend.

Structure and Setup

  • Component specs live in cypress/component/** and are grouped by capability (for example, manualAccountCreation, fineAccountEnquiry, shared pages/).
  • Prefer the shared router-outlet setup in cypress/component/fineAccountEnquiry/accountEnquiry/setup so specs can register routes, provide shared services, intercept APIs, and navigate to the component under test.
  • Extend the shared setup rather than creating a new mount helper, unless it causes regressions.

Page Object Model Usage

  • Do not call cy.get directly when a POM exists.
  • Import Actions or Flows from cypress/e2e/functional/opal/actions/** or cypress/e2e/functional/opal/flows/** and use their methods against the mounted component.

Selectors and Hooks

  • Use stable selectors from cypress/shared/common.locators.ts and cypress/shared/selectors/**.
  • If a component lacks a hook, add a semantic ID or data attribute in src/app first, then expose it via the selector modules so component and E2E tests stay in sync.

Mocks, Intercepts, and Tags

  • Store API intercept fixtures beside each spec in <spec-folder>/mocks/**.
  • Copy or extend existing mock files so scenarios stay isolated.
  • Use local intercept helpers in <spec-folder>/intercept/** with the router-outlet setup.
  • Tag tests with Jira IDs when scoping to acceptance criteria (example: { tags: ['@PO-604'] }).

Running a Spec

  • Run a single component spec with: yarn cypress run --browser chrome --component --spec 'cypress/component/fineAccountEnquiry/accountEnquiry/AccountEnquiry.cy.ts'

Handling Real Product Bugs

  • If a component spec fails due to a real product bug, do not change application code to force a pass.
  • Skip or mark the test pending and explain the failure in the task update.
