Sorry about the noise, but you know how it goes: you publish something to the public, and soon after notice another edge or two to polish. :-) The module definition used to include "#:declarative #f" which I've now removed as it wasn't necessary anymore. Apparently it was necessary due to a non-standard global variable exposed by the old implementation, called test-log-to-file. It was possible to set this to #f to disable logging. I'm not sure if anyone ever used that, but with the new implementation you can achieve the same by executing: (test-runner-current (test-runner-simple)) As an additional extension, you can now also provide a file name argument to test-runner-simple to change the name of the log file. - Taylan
