Explore realistic interface states, programmable services, and complete user journeys in one calm workspace built for modern quality practice.
Follow the same scenario through interaction, service behavior, and inclusive feedback without losing the user outcome.
Target meaningful controls, move through real validation, and assert the state change that communicates success.
Control authentication, validation, success, latency, and fault conditions so each edge case stays repeatable.
Make roles, labels, focus movement, keyboard behavior, and announced status part of the same quality story.
Each capability adds useful depth while the starting point stays clear, calm, and approachable.
Move beyond generic demos with meaningful workflows and data across the industries users recognize.
Loading, empty, invalid, slow, unauthorized, failed, and successful outcomes.
Roles, labels, focus paths, keyboard behavior, and meaningful status feedback.
Component guidance, realistic examples, recipes, and sample automation code.
Practice with Playwright, Cypress, Selenium, and direct API clients.
Keep passed checks, timing, and connected layers visible without adding noise.
Open a focused component, control a service, or follow a complete journey—with relevant help one step away.
Validation, keyboard behavior, complex controls, selectors, and visible state.
Open UI Labs →Uploads, downloads, sorting, filtering, pagination, routing, and retained state.
Explore components →REST, GraphQL, authentication, latency, faults, assertions, and request history.
Open API Mock →Commerce, banking, healthcare, identity, education, and cross-layer outcomes.
Choose a workflow →Roles, labels, focus, keyboard paths, errors, and clearly announced feedback.

Use Playwright’s request context to exercise the configured Testbox endpoint and assert the response.
import { test, expect } from '@playwright/test';
test('creates a Testbox API user', async ({ request }) => {
const response = await request.post(
'https://app.uassert.com/api/users',
{ data: { name: 'Testbox QA', role: 'tester' } }
);
expect(response.status()).toBe(201);
expect(await response.json()).toMatchObject({ role: 'tester' });
});Use Cypress request automation to create a scenario and keep the service result visible beside the test.
describe('Testbox API', () => {
it('creates a user', () => {
cy.request('POST',
'https://app.uassert.com/api/users',
{ name: 'Testbox QA', role: 'tester' }
).then(({ status, body }) => {
expect(status).to.eq(201);
expect(body.id).to.be.a('number');
expect(body.role).to.eq('tester');
});
});
});Create deterministic data with an API call, then open the related Testbox surface with Selenium.
import requests
from selenium import webdriver
response = requests.post(
'https://app.uassert.com/api/users',
json={'name': 'Testbox QA', 'role': 'tester'}
)
assert response.status_code == 201
driver = webdriver.Chrome()
driver.get('https://app.uassert.com/studio.html#api')
assert 'Testbox' in driver.title
driver.quit()Practice focused interface controls, complex state, API behavior, accessibility paths, and complete workflows across realistic domains.
No. Open the playground in the browser and begin exploring. Your automation framework can connect to the available UI and API targets.
Yes. Framework recipes demonstrate UI and API automation patterns for all three tools.
It provides repeatable service scenarios for success, authentication, validation, latency, and faults, with assertions and request history.
Yes. Roles, labels, keyboard paths, focus behavior, errors, and announced status are built into the practice experience.
Open the dedicated Help & Docs area or use a contextual help action from the component or domain you are practicing.
Explore realistic behavior, control the state, and follow the complete outcome.
