certainly! speeding up playwright scripts can be crucial for improving test execution times, especially when dealing with applications that make a lot of network requests. one effective technique is to use *request interception* to control and manipulate network requests. by intercepting requests, you can skip loading unnecessary resources, mock api calls, or serve responses from a cache.

what is request interception?
request interception allows you to listen for network requests made by the browser and either modify or cancel them. this is useful for speeding up tests by avoiding unnecessary network calls, or for mocking responses to avoid hitting real servers.

benefits of request interception
1. **speed**: skip loading images, styles, or other assets that are not relevant for the test.
2. **mocking**: simulate api responses without hitting the actual server.
3. **control**: modify requests or responses as needed for your test scenarios.

setting up playwright for request interception
to get started, you need to have playwright installed. if you haven't already, you can install it using npm:



example: speeding up tests with request interception

here's a step-by-step guide with code examples.

step 1: basic setup

create a file called `interception-example.js` and set up a basic playwright script:



step 2: adding request interception

now, let's add request interception to skip loading images and mock an api response.



explanation of the code:
1. **request interception**: we use `page.route()` to intercept all network requests.
2. **abort image requests**: if the request is for an image (resource type), we abort it using `route.abort()`.
3. **mock api response**: if the request url matches our condition (e.g., `/api/data`), we fulfill it with a mocked response.
4. **continue other requests**: for any other requests, we simply call `route.continue()` to let them proceed as normal.

conclusion
by using request interception, you can significantly spe ...
