How do I set up a multi-stage test pipeline in sbt?

Question

Specifically, for a Scalatra project, but the question probably applies to most.

For example, I typically want to run:

• unit tests
• code quality checks (coverage, duplication, complexity, jsLint!)
• integration tests (not too many!)
• acceptance tests (usually a "pre-checkin" subset)
• regression tests (basically the same as acceptance tests, but a bigger set)
• performance tests

I want to run different subsets of these by context - i.e. after a simple code change I might just run the first three; before checking in I might want to run a bigger set, and the Continuous Integration server might have a "fast" and a "slow" build that have even bigger sets.

The basic sbt docs seem to assume a single "test" target - is there a recommended way to implement multiple test phases like this?

You may want to look at this blog about using integrated testing with SBT and Hudson:

Then, to add your own actions you can use this page:

Basically, though, you will probably want to add a new action for each of your testing steps, in order to get the particular events you want to happen.
