Estimated hours taken: 0.5 Fix bugs that were stopping *.res and *.out files being cleaned up properly. tests/Mmake.common: tests/general/accumulator/Mmakefile: tests/invalid/Mmakefile: tests/misc_tests/Mmakefile: tests/tabling/Mmakefile: tests/term/Mmakefile: tests/valid/Mmakefile: tests/warnings/Mmakefile: Make cleaning tasks depend on (real)clean_local rather than (real)clean. This is because tests/startup and tests/shutdown use the *_local targets. tests/general/Mmakefile: Fix bugs in the recursive mmake calls.
The Mercury test suite is (dis)organized into a directory hierarchy. Each subdirectory has a script named "runtests" that runs the tests in that subdirectory; these indicate the presence of any errors by returning a nonzero exit status. The runtests script in each directory invokes the runtests scripts in all subdirectories, and propagates any nonzero exit status upwards. Both the bootcheck script and the nightly script use the main runtests script to run all the tests. benchmarks This directory contains Mercury versions of the benchmarks. These tests work by comparing the output of the Mercury and the NU-Prolog versions. debugger This directory is for testing mdb, the Mercury debugger. Programs are compiled with deep tracing turned on. The tests in this directory are not performed if the base grade is `jump' or `fast'. debugger/declarative This directory is for testing the declarative debugging features of mdb. general This directory is for general test cases. (It might be a good idea to split this into tests of particular features and regression tests that check for old bugs. But for the moment, just about everything goes in here.) These tests work by comparing the output of the Mercury and the NU-Prolog versions. hard_coded This directory is for tests of features that don't work in NU-Prolog. The expected output of the program has to be hard-coded in a hand-written `.exp' file, rather having the `.exp' file be generated automatically using NU-Prolog. valid This directory is for test cases that are not complete programs. We just check that the files compile. invalid This directory is for test cases that are invalid programs. We check that the files do *not* compile. warnings This directory is for tests of compiler warnings. These work by comparing the warnings emitted by the compiler with those given in the hand-written `.exp' file. To regenerate the expected output files for the benchmark and general directories, execute the "generate_exp" script in this directory.
