cl-test-grid is a project for collaborative testing of Quicklisp
libraries on different platforms and implementations. cl-test-grid runs the test suites of dozens of libraries available through Quicklisp on your machine on whatever Common Lisp implementations you have available, then submits a report about the test runs to a public repository. This helps catch and fix bugs in Lisp libraries and implementations.
All the reports are available at http://common-lisp.net/project/cl-test-grid/. A quick summary can be found at http://common-lisp.net/project/cl-test-grid/test-runs-report.html
You can get cl-test-grid and run the tests yourself from https://github.com/cl-test-grid/cl-test-grid
