Predictable API data for every test run.
Isolated test data, real auth flows, and full request logs - so your Playwright, Cypress, and CI suites assert against real HTTP responses, not mocks.
The test data problem
Reliable tests need reliable data. But most suites run against shared staging environments with unpredictable state, mock servers that drift from production, or local setups that break in CI.
Common testing pain points
- Shared staging data changes between runs
- Mock servers don't match real API behaviour
- No visibility into what the API actually returned
- Setting up auth for test users is a separate project
How ReqRes helps QA
Each project is its own namespace - collections, users, logs, all separated. No cross-contamination between test suites or team members.
Assert against actual status codes, headers, and JSON shapes - not mocked fixtures that drift over time.
Every request is logged with method, path, status, and timing. Search logs to debug failed assertions.
Magic links create test users and return session tokens. Test authenticated endpoints without standing up an auth server or maintaining test credentials.
A typical QA workflow
Isolate test data from production. One project per environment or test suite.
Create collections with schemas and seed records via the API. Predictable shapes every time.
Playwright, Cypress, or cURL - hit real HTTP endpoints and assert against real responses.
Search request logs by method, path, or status to pinpoint what went wrong.
Example: Playwright test
import { test, expect } from '@playwright/test'
// Get a session token in your test setup - three API calls, no auth server
let sessionToken: string
test.beforeAll(async ({ request }) => {
// Send magic link (in test mode, token is returned directly)
await request.post('https://reqres.in/api/app-users/login', {
headers: { 'Content-Type': 'application/json', 'x-api-key': 'pk_test_...' },
data: { project_id: 'proj_test', email: '[email protected]' }
})
// Verify and get session token
const verify = await request.post('https://reqres.in/api/app-users/verify', {
headers: { 'Content-Type': 'application/json' },
data: { token: 'token_from_response' }
})
sessionToken = (await verify.json()).session_token
})
test('creates and retrieves a record', async ({ request }) => {
// Seed a record
const create = await request.post(
'https://reqres.in/app/collections/todos/records',
{
headers: {
'Authorization': `Bearer ${sessionToken}`,
'Content-Type': 'application/json'
},
data: { data: { title: 'Test todo', completed: false } }
}
)
expect(create.status()).toBe(201)
// Assert it appears in the scoped list
const list = await request.get(
'https://reqres.in/app/collections/todos/records',
{ headers: { 'Authorization': `Bearer ${sessionToken}` } }
)
const body = await list.json()
expect(body.data).toContainEqual(
expect.objectContaining({ title: 'Test todo' })
)
expect(body.meta.total).toBeGreaterThan(0)
})
// No mock server. No shared staging. No fixture files.
// Real HTTP, real auth, real data - deterministic every run.Why QA teams choose ReqRes
No Docker services. No local servers. Hit the API from GitHub Actions, CircleCI, Jenkins - anywhere.
Every test run starts with the data you seeded. No shared-environment surprises. No state leaking between suites.
Test login flows, token verification, and scoped data access - without maintaining an auth server or a credentials file.
Every request logged with method, path, status, and timing. When a test fails, search the logs instead of guessing.
