Can I upload Playwright results to Testomat.io without configuring an external S3 bucket?

Yes for results, no for artifacts.

Your test results, the tests, their statuses, and their steps, always sync to Testomat.io with no S3 needed.

If you only need results (no S3)

Run your Playwright tests with the Testomat.io reporter as usual.
Open your project in Testomat.io and check that the run is there, with your tests, statuses, and steps.

That’s all, there’s no extra setup.

Artifacts are the exception. Screenshots, videos, and traces can only be stored in your own S3 bucket, because Testomat.io doesn’t store files itself.

If you also want artifacts (screenshots, videos, traces)

Create an S3 bucket in your own cloud storage.
Go to Settings in Testomat.io, then Artifacts.
Enter your bucket details, then turn on “Share credentials with the reporter”.
Run your Playwright tests again.
Open the run and confirm the artifacts now appear next to your results.

Connecting the bucket once is enough, the reporter reads the details from your project, so there’s nothing to set up in your environment.
