Intercepting API responses

Use the same approach - fixtures and define page.on there.

However, it's just a listener and does not stop any execution so I would recomment try-catching the response.

thanks @skorp32 for your reply. I think the challenge is how to define page.on in there there? the implementation of those event listeners is not very straightforward it seems. maybe PW has an easier way to achieve that result?

Are you using apiRequest.newContext() or page.request / browserContext.request ? You won't have any events without a browser/page to have the events. Ad-hoc requests would need to be handled manually

someFixture: [
    async ({ page }, use) => {
      page.on('response', async response => {
        // do stuff with response
      })

      await use()
    },
    { auto: true },
  ],

that's an automatic one, but you can do same thing with simpel fixture as well

and as I mentioned, try-catch response body because on navigation (and perhaps other stuff) response bodies are dumped so you might get an error
