[Question] Is there a way to return an api request response time?

[BekaOkromchedlidze]

I am using the request fixture for API testing and I am just wondering is there a way to find what the api response time was?

I don't think we have a feature like this. But request API is not done through the browser, so we don't have access to the detailed timing anyways.

Did you see this info? Maybe it can helps you

Pavel Feldman (@pavelfeldman) I think this would be a very nice feature to have for api testing. It would be used to test performance sanity to make sure we get a response in an acceptable time.

Anton Klepik (@klepik1990) this is for the page fixture. We don't have this option for the request fixture

It's not completely accurate, but you can do something like:

const requestDate = new Date();

// your request: await request ...

const responseDate = new Date();

console.log(responseDate - requestDate);

I agree that this feature will be very useful 😄

i agree this feature should be implemented in request fixture , as we need to do the performance of the api

Another workaround is to use testStep.duration: https://playwright.dev/docs/api/class-teststep#test-step-duration

Feature ought to be integrated within the request fixture.

Hey folks! Could you share a little more about your usecases? Specifically I'm curious about the granularity of timing you need. Do you care about the full roundtrip time, or also about time to first byte or time taken by a potential TLS handshake?

It would be ideal to have something similar to what k6 has: https://grafana.com/docs/k6/latest/examples/get-timings-for-an-http-metric/

At least just the duration.
