Can you try with empty value? That is common OpenShift fuckup.

[davidor]

Good point. I added a new test (TEST 19) which is basically a copy-pasta of TEST 18. The only difference is an env. Any ideas to avoid this kind of duplication in Test::Nginx ?

[mikz]

No idea :( It really sucks to have this kind of duplication.

[mikz]

Maybe would be useful to test it on lower level - in busted.

[davidor]

Agreed. I thought about that, but then I saw that there are no unit tests for oauth, so I thought that it would be better to just complete the existing integration tests for now. Maybe this is something we could address in a future PR.

[mikz]

Definitely. 👍
