is there some way to mark to orca that this isn't a real credential? i feel like it might complain although the tests seem to pass now?

[obs-gh-mattcotter]

@obs-gh-nikhildua do you know if this is possible? Maybe we can figure that out if it ever does complain?

how did the snapshots get generated currently? and when am I expected to update these?

Good question! I started each file as identical copies of the output of the config command on my mac, then I ran the tests and applied the diff. I looked at the output at the end, and it's what I would expect.

For updating this, whenever we modify our bundled config or add more observe-agent config options we may expect some diffs here. This test is supposed to make it easy to tell when our bundled config changes and to make sure we always consider that during code reviews. It won't say if the change is good or expected, that's up to the reviewers, but it will always flag a change which should catch mistakes.
