How to add a self-defined unit-engine to arcanist

Question

I'm using arc as the tool for code reviewing. The bin/arc is not in the git repo, but I wanna add a test engine in the git repo. Thus I create directories test-engine, in the test-engine:

__phutil_library_init__.php
__phutil_library_map__.php,
src/PyEngine.php

the phutil_library_init.php:

    <?php

    phutil_register_library('PyEngine', __FILE__);

the __phutil_library_map__.php:

    phutil_register_library_map(array(
        '__library_version__' => 2,
        'class' =>
        array(
          'PyEngine' => 'src/PyEngine.php',
        ),
        'function' =>
        array(
        ),
        'xmap' =>
        array(
          'PyEngine' => 'ArcanistUnitTestEngine',
        ),
    ));

the .arcconfig:

{
    "phabricator.uri" : "blabla",
    "load" : [
      "test-engine"
    ],
    "unit.engine" : "PyEngine"
}

but when I run arc unit, it reports error:

 phutil_register_library_map(array(
      '__library_version__' => 2,
      'class' =>
      array(
        'PyEngine' => 'src/PyEngine.php',
      ),
      'function' =>
      array(
      ),
      'xmap' =>
      array(
        'PyEngine' => 'ArcanistUnitTestEngine',
      ),

How can I add the unit engine properly?

Answer 1

Did you ran arc liberate again after adding your class (and was it used to actually create your lib in the first place)?

You can get a little info (this is not officially supported yet) here: https://secure.phabricator.com/book/phabcontrib/article/adding_new_classes/
