This directory contains XEmacs' automated test suite. The usual way of running all the tests is running `make check' from the top-level source directory. The test suite is unfinished and it's still lacking some essential features. It is nevertheless recommended that you run the tests to confirm that XEmacs behaves correctly. If you want to run a specific test case, you can do it from the command-line like this: $ xemacs -batch -l test-harness.elc -f batch-test-emacs TEST-FILE If something goes wrong, you can run the test suite interactively by loading `test-harness.el' into a running XEmacs and typing `M-x test-emacs-test-file RET RET'. You will see a log of passed and failed tests, which should allow you to investigate the source of the error and ultimately fix the bug. Adding a new test file is trivial: just create a new file here and it will be run. There is no need to byte-compile any of the files in this directory -- the test-harness will take care of any necessary byte-compilation. Look at the existing test cases for the examples of coding test cases. It all boils down to your imagination and judicious use of the macros `Assert', `Check-Error', `Check-Error-Message', and `Check-Message'.
