This directory contains a test suite for testing Common Lisp (CLtL1)
implementations.

In its original version it was built by

    Horst Friedrich, ISST of FhG         <horst.friedrich@isst.fhg.de>
    Ingo Mohr, ISST of FhG               <ingo.mohr@isst.fhg.de>
    Ulrich Kriegel, ISST of FhG          <ulrich.kriegel@isst.fhg.de>
    Windfried Heicking, ISST of FhG      <winfried.heicking@isst.fhg.de>

for their Common Lisp implementation named XCL.

What you see here is a version adapted to CLISP and AKCL by

Operation:
----------

The files *.tst contain test forms and their corresponding results.
You may feed the test forms one by one to an interpreter and compare the
results you get with the predicted ones.

This tasks is automated by tests.lisp. Run

      > (load "tests")
      > (run-all-tests)

The differences between the results and the predicted ones are
recorded in *.erg files. Empty *.erg files are removed.
If you can't find any *.erg files after running the tests, then your
implementation has passed the tests!


Notes:
------

* The test suite covers only CLtL1.

* The test suite is not "complete" in any sense. Anyway, it may be useful:
  It has uncovered at least five severe bugs in CLISP and nineteen bugs
  in AKCL.

* Some results are implementation dependent. When using other implementations
  than XCL, CLISP and AKCL, you may wish to insert your "predicted results",
  protected by #+ and #-. Think twice before doing so as you may be
  deliberately ignoring a bug in your implementation.

* The test "tprint" is currently not used by tests.lisp.

* Additions are welcome.
