Chrome Flags for Testing

One of the challenges as Privacy Sandbox and 3PCD roll out is that not all Chrome browsers are configured to use the APIs the same way, and many sites (including test sites) may not have all their "paperwork" done with Chrome. This includes things like Chrome version but also settings for your own browser behavior and how Chrome will choose to interact with implementing sites, like this one.

Here we'll go over some of what you can do to have these tests work for you locally.

Chrome Version

Chrome > 120 should do it, latest can't hurt

Bypass Attestation

You can do this by visiting chrome://flags and then setting the
#privacy-sandbox-enrollment-overrides (Privacy Sandbox Enrollment Overrides) to include the URL for these sites:

          
    https://www.privacy-sandbox-testing-one.com,
    https://www.privacy-sandbox-testing-two.com,
    https://www.privacy-sandbox-testing-three.com,
    https://www.pst-dsp.com,
    https://www.pst-ssp.com
          
        

Other Flags

Here are some other flags I have set locally.
