The MINIX 3 sources include a test suite in /usr/src/test. Primarily, it tests POSIX conformance. This page describes how to run the test suite.
To test MINIX 3, at the command prompt (#) type
cd /usr/src/test make
and wait until it completes all the compilations.
To test the system, type
cd /usr/src/test ./run
to run the test programs. Note: the full test set will be performed only when you are root, so you should start the “run” script as root. The script will perform some tests as the “bin” user, and it will automatically change the owner of the /usr/src/test directory to “bin” for that purpose. If you really want to run the script as a non-root user, make sure to perform that step manually first.
