1. Playwright API Testing mocking data Playwright is primarily known for its capabilities in browser automation and end-to-end testing. you can combine it with other tools and techniques to achieve data mocking during API testing. - Playwright Automation Online Training Here's a general approach: Using Playwright for API Testing: 1. Install Playwright: You need to install Playwright in your project. You can do this using npm (Node Package Manager). For example: ```bash npm install playwright ``` 2. Write API Tests: Use Playwright to write API tests. Playwright supports making network requests, so you can use it to interact with your APIs. 3. Integrate Mocking Library: To mock data during API testing, you can use a separate library like `nock` or `msw` (Mock Service Worker). - Playwright Course Online - Install the mocking library and set up mocks for your API endpoints. ```bash npm install nock ``` Example with `nock`: ```javascript const nock = require('nock'); // Mocking a GET request nock('https://api.example.com') .get('/data') .reply(200, { key: 'mocked-value', }); ```

2. This will intercept any HTTP request to `https://api.example.com/data` and reply with the specified mocked data. - 4. Combine Playwright and Mocking: Use Playwright to launch your browser, navigate to your application, and trigger the API calls. Ensure that your mocked data is returned instead of actual API responses. - Playwright Automation Testing Hyderabad ```javascript const { chromium } = require('playwright'); (async () => { const browser = await chromium.launch(); const context = await browser.newContext(); const page = await context.newPage(); await page.goto('https://your-application.com'); // Your Playwright API testing code here, trigger API calls await browser.close(); })(); ``` Remember to set up your mocks before triggering the API calls in Playwright. Example Using MSW (Mock Service Worker): If you prefer `msw`, which is specifically designed for mocking in-browser, you can integrate it with Playwright: 1. Install `msw`: ```bash npm install msw ``` 2. Set up your mocks: ```javascript // src/mocks/handlers.js import { rest } from 'msw'; export const handlers = [ rest.get('https://api.example.com/data', (req, res, ctx) => { return res(ctx.json({ key: 'mocked-value' })); - Playwright Online Training }),

3. ]; ``` 3. Start the MSW server: ```javascript // src/mocks/server.js import { setupServer } from 'msw/node'; import { handlers } from './handlers'; const server = setupServer(...handlers); beforeAll(() => server.listen()); afterAll(() => server.close()); - Playwright Course in Hyderabad ``` 4. Integrate with Playwright: ```javascript // src/tests/api-test.js import { chromium } from 'playwright'; import { server } from '../mocks/server'; beforeAll(() => { server.listen(); }); afterAll(() => { server.close(); }); test('Your API test', async () => { const browser = await chromium.launch(); - Playwright Automation Training const context = await browser.newContext(); const page = await context.newPage(); // Your Playwright API testing code here, trigger API calls await browser.close();

4. }); ``` This way, `msw` intercepts and handles API requests made by Playwright, returning the specified mocked data. Adjust the code based on your specific use case and testing framework. - Playwright Automation Testing Hyderabad Visualpath is the Leading and Best Institute for learning Playwright Course in Hyderabad.
