944693 - Use shared secret auth in tests instead of oauth

Status: RESOLVED WONTFIX

Description

[Mathieu Pillard [:mat]]

Pretty much all of our API tests that test views/resources rely on OAuthClient, but the main authentication scheme is what fireplace, rocketfuel etc use, and that's SharedSecret. In fact, we even had a bug recently (bug 943471) that was due to an edge case in RestSharedSecretAuthentication code; view tests would have caught that if they had used Shared Secret.

I propose we introduce a new test client class, SharedSecretClient, and use that in our API tests. (It might even be faster, who knows)
