Interesting idea. Here's my suggestion for the issues you raised:

1. The makefile for the module must be installed along with the test files in order to re-run tests, and
2. yes, the output must be captured and stored somewhere -
3. so I'd suggest (similar to what AutoSplit does for AutoLoader - store baz.al for e.g. Foo::Bar::Quux in auto/Foo/Bar/Quux/baz.al) to install them in test/Foo/Bar/Quux/t/{00_use.t,01_foo.t,...}. Makefile and logs from test runs could live there, also.

Since the test is a separate tree, it doesn't mess with the lib tree.

The Makefile could live in test/Foo/Bar/Quux, the logs could be written to test/Foo/Bar/Quux/logs.

What do you think?
