I think the whole suite should be revisited and re-implemented. Most of the time tests are getting slow when we touch external dependencies (which includes a database). So the first thing that will be most notable is to get rid of those dependencies. Most of the time we don't really want to test the persistence, but rather how XYZ behaves. My problem is that I am too lazy to properly isolate database tests, so most of the time I just use fixtures with SQLite database instead of stubbing/mocking. SQLite database is much faster to run than any other for the tests. So the first thing to do is to try to isolate Database access. First try SQLite, then try to hack to use SQLite in-memory DB, then srub and mock. > Some tests create 10 - 15 models, are parse some big json > file before running *each* example, so I have a fair idea why they are > running so slowly. > The time cost of creating 100 objects is ridiculously cheap.

The speed of specs themselves is not a concern for me, but rather the startup time. -- You received this message because you are subscribed to the Google Groups "Ruby or Rails Oceania" group.
