Think of end to end tests
When developing the endpoints please consider how you would write end to end tests.
In v1.1 end to end tests can be complicated to write. Not only is there the challenge of timeouts and replication of the data on your server but also some of the endpoints just stop working temporarily.
Over the years I have reported many bugs that could have been prevented if Twitter did have end to end tests.
Please do think about writing these tests and think through how developers of libraries can write similar tests.
