Usage: ./test.php [options] [searchstring]
where [options] can be a mix of these:
-h Show this help message and exit.
-d=[difftool] Show the diff of the actual output vs. the reference when a
test fails; uses 'diff -b -B -t -u' by default.
The test is aborted after the first failure report, unless
you also specify the '-g' option ('go on').
-g Continue executing the other tests when a test fails and
option '-d' is active.
-C Regenerate ('compile') the reference output files from the
given inputs.
WARNING: ONLY USE THIS OPTION WHEN YOU HAVE ASCERTAINED
THAT lessphp PROCESSES ALL TESTS CORRECTLY!
The optional [searchstring] is used to filter the input files: only tests
which have filename(s) containing the specified searchstring will be
executed. I.e. the corresponding glob pattern is '*[searchstring]*.less'.
The script EXIT CODE is the number of failed tests (with a maximum of 255),
0 on success and 1 when this help message is shown. This aids in integrating
this script in larger (user defined) shell test scripts.
Examples of use:
- Test the full test set:
./test.php
- Run only the mixin tests:
./test.php mixin
- Use a custom diff tool to show diffs for failing tests
./test.php -d=meld
