How can I handle network interactions such as waiting for responses, handling requests, and modifying requests and responses in Playwright after a button click?


Sure, you can handle network interactions in Playwright after a button click. Here's how:

Waiting for a Response

Use page.waitForResponse() to wait for a response after a button click. This method lets you specify a URL pattern or a predicate function that takes in a Response object.

const responsePromise = page.waitForResponse('https://ray.run/api/fetch_data');
await page.getByText('Update').click();
const response = await responsePromise;

Handling Requests

Playwright lets you handle requests with page.route(). This method intercepts network requests and lets you decide how they should be handled.

await page.route('https://ray.run/*', route => {
  const headers = route.request().headers();
  delete headers['X-Secret'];
  route.continue({ headers });

Aborting Requests

You can abort certain types of requests using route.abort().

await page.route('https://ray.run/*', route => {
  return route.request().resourceType() === 'image' ? route.abort() : route.continue();

Modifying Responses

If you need to modify responses from your server-side scripts or APIs during testing scenarios, use APIRequestContext along with route.fulfill().

These are just some examples of what you can do with Playwright's networking capabilities. Depending on your specific needs, there might be more advanced techniques available within Playwright.
