I looked at your test harness and it looks very interesting. It is very
similar in spirit to what I tried to do with corpus based tests[1]. The
corpus based tests let you specify a file where each line is a test
case. The first column is the expected input and the second column is
the expected output. There is a test in svn and it is run when you type
make check. However the test is very basic and nobody seems to have
picked up on it or ever used it. Have a look at the README in
tests/table_test_corpuses.
Two points about your test harness:
1. Implemented in Python: Don't get me wrong, I like Python. But
implementing the test harness in Python means that a user needs to
have it installed and also needs to have the Python bindings
installed before she can run the tests.
2. Doesn't run locally: As I said above you need to install the Python
bindings first before you can run the tests.
We can decide that these are no big problems and a user can be expected
to install Python and the Python bindings before running the test
harness. On the other hand the corpus based tests are implemented in
Perl and use the standard lou_translate, i.e. no need to install Python
and they can be run from within the liblouis src directory without any
installation. I think I could easily extend the Perl script to cover
your use case (just split the line on tabs instead on any white space).
Let me translate your example into a (what I called) corpus based test
and we could then possibly merge the two efforts.
Thanks
Christian
