I have a fresh Laravel Boilerplate running on a Laravel Homestead environment which runs perfect.
The php -v command was returning me this info

I was searching how to setup phpunit's code coverage to work, and found that I need xDebug to make it work. Googled a bit more and found the xon homestead command, which enable xDebug extension. So I ran it, and found the xDebug extension was enabled, as a new php -v shows:

Also I needed to add php-code-coverage dependency with composer require --dev phpunit/php-code-coverage:4.0.8 (specific version, because I was getting some requirements errors while trying to install newest one).
Then I ran phpunit --coverage-clover=coverage.xml and got this fatal error:
PHPUnit 5.7.19 by Sebastian Bergmann and contributors.

I got a feeling this is related to Laravel Facades, and this lead me to think phpunit isn't running my autoload file, but the attribute bootstrap="bootstrap/autoload.php" exists in phpunit.xml file by default.
Don't know where to go from here, out of ideas of what is wrong.
EDIT: My Homestead version is 5.1.0
The fresh Boilerplate install comes with a phpunit.xml file. Inside it, there is a filter tag with this data
<filter>
<whitelist processUncoveredFilesFromWhitelist="true">
<directory suffix=".php">
./app
</directory>
</whitelist>
</filter>
I'm not a PHPUnit expert, so I played a little with the XML, and found that the whitelist tag was causing it to break. I played a little more with it, and found that if I remove the processUncoveredFilesFromWhitelist="true" attribute, phpunit command is able to run and generate code coverage I needed.
Just a note.
Unfortunately, without code coverage tests used to take ~1.5 minute to run, and with code coverage turned on with this trick, tests are taking ~11 minutes.
As the question is related to generate the code coverage report, I'll mark this as accepted, and will keep this question updated if I find anything that might help someone with same problem as me.
