Shell Tester is a test suite for Bourne-compatible shells. It consists of a number of test cases, each of which runs a small program using the shell to be tested. The standard output, standard error, and exit status of the shell are recorded and compared to the expected values. How To Use To use shell tester, first run the configure script and tell it the shell to test: ./configure --shell-to-test /bin/sh Then run ~make check~ to run the tests. You can use the -j option to make to run multiple tests in parallel. For example: make -j 8 check
