Test Manager
Test Manager is a unit testing framework for Scheme. The design is loosely inspired by the xUnit family of testing frameworks. At present it only works for MIT Scheme and Guile, but since it runs on two different implementations it shouldn't be that difficult to port to more. I just haven't done that.
I am releasing this software because I hope it will be useful. I've used it long enough myself that I am not embarrassed to throw it out to the world, but I by no means guarantee absence of bugs. Let me know if you find any — especially if you have suggestions for how to fix them.
Download: test-manager-1.1.tar
Install: Test Manager is distributed in source form -- just unpack the tarball anywhere you like, and load the test-manager/load.scm file inside to use it. You can probably compile it if you wish, but I haven't paid any attention to compilation because I don't know how to write compiler declarations portably.
Use: Here's the API documentation. If you're upgrading from an earlier version, here's the change log.
