[Libclc-developers] test code

[Hallvard B F. <h.b...@us...>]

Some *.c files in CVS have the code
    #ifdef CLC_TEST
    int main() { test code...; }
    #endif
This does not work if a.c requires b.c and both have this code, since we
get duplicate main().  Also it means that the code must be compiled
twice: Once with CLC_TEST to test it, once without to build the library.

I think we instead should have a file test.c in each module directory
which tests the various functions in that module.

Furthermore, so that we can run the test code from 'make test', test.c
should not take user input and should not require the user to read the
output.  Instead it should just do some hard-coded tests and do
exit(EXIT_SUCCESS) without printing anything at success, and print an
error message to stderr and do exit(EXIT_FAILURE) if a test fails.

Or if that's too simplistic, it could take input from test.inp and write
output to test.log, and 'make test' could compare test.log with a
preexisting test.out.  But I think that can wait until we find we
actually need it.

Comments?
