  1. Quality.Catalyzed Playwright’s Network Mocking for Speed and Stability In modern testing, the stability and speed of test execution are critical. Playwright’s advanced network mocking feature helps achieve this by allowing developers/testers to intercept and manipulate network requests during tests. This approach enhances test reliability and also provides flexibility to simulate diverse scenarios without relying on live services. www.testrigtechnologies.com

  2. Quality.Catalyzed How It Works: Playwright’s route method empowers testers to intercept and mock API responses, ensuring predictable and stable test outcomes. await page.route('**/api/data', route => {   route.fulfill({     status: 200,     contentType: 'application/json',     body: JSON.stringify({ data: "mocked response" }), }); }); www.testrigtechnologies.com

  3. Quality.Catalyzed Key Benefits of Network Mocking: Reduced Test Flakiness Eliminate test failures caused by flaky or unavailable APIs, ensuring consistent results. Improved Test Speed Bypass network latency by responding locally, significantly enhancing test execution times. Simulate Real-World Scenarios Test diverse edge cases, such as error responses or large payloads, without backend changes. www.testrigtechnologies.com

  4. Quality.Catalyzed Example: Mocking API Responses import { test, Request } from "@playwright/test"; test.describe.parallel("Mock API response @mocking", () => { test("Mocked API response test for product details", async ({ page }) => { let interceptedRequest: Request | null = null; // Capture the route request to check if it's being intercepted await page.route( "https://parabank.parasoft.com/parabank/services/ bank/accounts/13455", (route) => { interceptedRequest = route.request(); route.fulfill({ status: 200, body: JSON.stringify({ id: 13455,

  5. Quality.Catalyzed type: "CHECKING", balance: 515.5, }), }); } ); // Verify that the route request was intercepted and mocked if (interceptedRequest) { console.log("Intercepted request URL: ", interceptedRequest.url()); // Log request URL console.log( "Intercepted request body: ", interceptedRequest.postData() ); // Log request body if needed expect(interceptedRequest).not.toBeNull(); // Ensure that request was intercepted } else { console.error("The request was not intercepted."); } }); });

  6. Quality.Catalyzed Testrig’s Playwright Network Mocking Expertise: We specialize in utilizing Playwright’s advanced features, including network mocking, to: Streamline Test Automation: Design stable and high- performance test suites by minimizing dependencies on external services. Ensure Comprehensive Testing: Simulate a wide range of scenarios, from edge cases to error handling, for better coverage. Accelerate Test Cycles: Reduce flakiness and improve speed by mocking API responses for faster feedback loops. With our proven expertise, we empower organizations to achieve reliable, scalable, and efficient testing processes, even for the most complex applications. www.testrigtechnologies.com
