Phabricator phpunit configuration - coverage

Question

I am trying to set up a coverage report within the DIFF view for phabricator. I have the following configs:

.arcconfig

{
  "project_id" : "SuperProject",
  "conduit_uri" : "https://phabricator.dev/",
  "unit.engine": "PhpunitTestEngine",
  "unit.phpunit.binary": "./vendor/bin/phpunit",
  "phpunit_config": "tests/phpunit.xml"
}

tests/phpunit.xml

<phpunit>
    <testsuite name="unit">
        <directory suffix="Test.php">unit/accountancy</directory>
        ....
        <directory suffix="Test.php">unit/store</directory>
    </testsuite>
    <logging>
        <log type="coverage-clover" target="../build/logs/clover.xml" />
    </logging>
</phpunit>

But when I run arc unit --coverage --json, I get something like the following:

{
  "0": {
    "namespace": null,
    "name": "Restriction\\CalculatorTest::testGetDiscount with data set #0",
    "link": null,
    "result": "pass",
    "duration": 0.00362205505371,
    "extra": null,
    "userData": "",
    "coverage": []   <-- why is it empty?
  },
  ...
}

Seems like arcanist is not picking up coverage info. I've tried even looking through the phabricator source code, but couldn't find a clue on how to enable that.

Any suggestions are very welcome!

add whitelist to your tests/phpunit.xml. Check https://phpunit.de/manual/current/en/code-coverage-analysis.html#code-coverage-analysis.whitelisting-files
