------------------------- An R6RS Test Suite ------------------------- ====================================================================== Files and libraries ====================================================================== Files that end ".sps" are R6RS programs. The main one is "run.sps", which runs all the tests. Files that end ".sls" are R6RS libraries. For example, "base.sls" is a library that implements `(tests r6rs base)', which is a set of tests for `(rnrs base)'. Many R6RS implementations will auto-load ".sls" files if you put the directory of tests in the right place. In general, for each `(rnrs <id> ... <id>)' in the standard: * There's a library of tests "<id>/.../<id>.sls". It defines and exports a function `run-<id>-...<id>-tests'. * There's a program "run/<id>/.../<id>.sps" that imports "<id>/.../<id>.sls", runs the tests, and reports the results. And then there's * "run.sps", which runs all the tests (as noted above) * "run-via-eval.sps", which is similar to "run.ss" but runs each set of tests via `eval' * "test.sls", containing `(tests r6rs test)', which implements the testing utilities that are used by all the other libraries * "contrib.sls" and "run/contrib.sps", which implement and run contributed tests; these tests might be contributed when someone finds a bug in an implementation that seems worth testing in other implementations; also, they may be difficult to pin to a particular R6RS library; finally, they may use extra libraries from the "contrib" sub-directory ====================================================================== Limitations and feedback ====================================================================== The test suite tries to cover all of the bindings of R6RS, and it tries to check a variety of uses One goal of this test suite is to avoid using `eval' (except when specifcally testing `eval'). Avoiding `eval' makes the test suite as useful as possible to ahead-of-time compilers that implement `eval' with a separate interpreter. A drawback of the current approach, however, is that if an R6RS implementation doesn't supply one binding or does not support a bit of syntax used in a set of tests, then the whole set of tests fails to load. A related problem is that each set of tests is placed into one function that runs all the tests. This format creates a block of code that is much larger than in a typical program, which might give some compilers trouble. In any case, reports of bugs (in the tests) and new tests would be very much appreciated. File either as a Racket bug report at http://bugs.racket-lang.org ====================================================================== Hints on running the tests ====================================================================== Ikarus (version 0.0.3+) ------ Put this directory at "<somewhere>/tests/r6rs" and run with "run.sps" cd <somewhere> ikarus --r6rs-script tests/r6rs/run.sps or run an individual library's test, such as "run/program.sps" as cd <somewhere> ikarus --r6rs-script tests/r6rs/run/program.sps Larceny (version 0.962) ------- Put this directory at "<somewhere>/tests/r6rs" and run with "run.sps" larceny -path <somewhere> -r6rs -program run.sps or run an individual library's test, such as "run/program.sps" as larceny -path <somewhere> -r6rs -program run/program.sps PLT Scheme (version 22.214.171.124) ---------- If you get an SVN-based or the "Full" nightly build, then these tests are in a `tests/r6rs' collection already. You can run all of the tests using mzscheme -l tests/r6rs/run.sps and so on. Otherwise, install this directory as a `tests/r6rs' collection, perhaps in the location reported by (build-path (find-system-path 'addon-dir) (version) "collects" "tests" "r6rs") Four tests fail; they correspond to documented non-conformance with R6RS. Ypsilon (version 0.9.6) ------- Put this directory at "<somewhere>/tests/r6rs" and run with "run.sps": cd <somewhere> ypsilon --sitelib=. --clean-acc tests/r6rs/run.sps or run an individual library's test, such as "run/program.sps" as cd <somewhere> ypsilon --sitelib=. --clean-acc tests/r6rs/run/program.sps
