API-first setup pattern in Cypress - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the API-first setup pattern in testing?

It means setting up test data or environment by calling APIs directly before running UI tests. This makes tests faster and more reliable.

beginner

Why use API calls for setup instead of UI actions in Cypress tests?

API calls are faster, less flaky, and avoid UI delays. They prepare the test state directly without depending on the UI.

How do you perform an API-first setup in Cypress?

Use cy.request() to call backend APIs to create or reset data before visiting the UI page.

intermediate

What is a key benefit of API-first setup pattern for test maintenance?

Tests are easier to maintain because setup logic is centralized in API calls, reducing UI changes impact.

beginner

Show a simple Cypress code snippet for API-first setup before a UI test.

cy.request('POST', '/api/users', {name: 'Test User'}).then(() => { cy.visit('/users') })

What does the API-first setup pattern primarily improve in tests?

A UI design

B Test speed and reliability

C Manual testing effort

D Database schema

API-first setup makes tests faster and less flaky by preparing data directly via APIs.

Which Cypress command is commonly used for API-first setup?

A cy.request()

B cy.get()

C cy.visit()

D cy.click()

cy.request() sends HTTP requests to backend APIs, perfect for setup.

When should you prefer API-first setup over UI setup?

A When manual testing is preferred

B When UI is very fast

C When UI is slow or unstable

D When no backend exists

API setup avoids UI delays and flakiness, improving test stability.

What is a common risk if you do NOT use API-first setup?

A Tests skip setup

B Tests run faster

C Tests become more reliable

D Tests may be slower and flaky

Without API setup, tests rely on UI which can be slow and flaky.

Which is NOT a benefit of API-first setup pattern?

A Direct UI interaction

B Faster test execution

C Less flaky tests

D Easier test maintenance

API-first setup avoids direct UI interaction for setup.

Explain how the API-first setup pattern improves Cypress test reliability and speed.

Think about how calling APIs directly helps tests run better.

Describe a simple example of using API-first setup in a Cypress test.

Imagine you create a user via API before opening the user page.
