treef uses a simple end-to-end test system. Test cases are defined by
complementary test_name.in and test_name.out files in the tests/
directory. Infiles specify input to treef and outfiles the expected output. Take
a look at tests/basic.in and tests/basic.out for an example.
Tests are run using
make test
which simply invokes the test.sh script. test.sh scans the tests/
directory for infiles and outfiles and runs them through ./treef. Any
discrepancies it encounters are output as a diff.
Creating new test cases is easy with
./gen-test.sh test_name1 test_name2 ...
The test generator will open up an editor for each infile and then an outfile
prefilled to pass using the current ./treef. Not saving the infile will cancel
the operation.
