Test APIs in Playwright (with E2E tests)

 Perform following steps,

1. In playwright.cofig.ts, create a project
• Provide test name:
• Provide testDir:
• In use:
• Provide baseURL:
• Provide extraHTTPHeaders:
• 'Accept':
• 'Content-Type':
2. In test, call back request instead of page
3. In request.METHOD('URL')
• request.get('URL')
• request.post('URL', {body})
4. Get the response in a variable
• const response = request.get('/products')
• For status, response.status()
• For header, response.headers()
• For body, response.body()
• For JSON, response.json()
• Also others availble
5. For assertions, use expect
• For status, expect(response.status()).toBe(200)
• For header content type match
• expect(response.headers()['conten-type']).toContain('application/json')
6. Get the response body in a variable
• const responseBody = response.json()
7. For assertions in the body
• expect(responseBody).toHaveProperty('success', true)
• expect(responseBody).toHaveProperty('data')
• expect(Array.isArray(responseBody.data)).toBe(true)
8. Run test project-wise, run with the following command
• npx playwright test --project project_name_given_playwright.config
