When generating HTML documentation, I'm getting the following warning (the warning is repeated many, many times). The output seems okay, as far as I've been able to tell, however.

Warning:  count(): Parameter must be an array or an object that implements Countable in phar:///usr/bin/phpunit/php-code-coverage/Report/Html/Renderer/File.php on line 307

If any details are required regarding the environment or configuration I'd be happy to provide those.

Fixed by pr #554, probably worth cherry-pick the fix in 4.0 and 5.0

@remicollet @sebastianbergmann any chance of getting this fix cherry-picked over to support PHPUnit 5.7? I'd be happy to open a PR for it if it is something that would be considered!

PHPUnit 5.7 is no longer supported.

@jdpedrie PHPUnit 5.7 is not supported, which is entirely reasonable, but I have a pile of old code to support that I don't have the time or inclination to upgrade. Tests are generally run with an error handler that throws ErrorExceptions on warnings so this breaks tests, so I needed a workaround.

My branch has the fix applied to the 4.0 branch, and this can be used to provide the dependency for PHPUnit with composer, e.g. along the lines of the following

{
   "repositories": [ 
        {
            "type": "git",
            "url": "https://github.com/elyobo/php-code-coverage.git"
        }
    ],
    "require": {
        "phpunit/phpunit": "~5.0",
        "phpunit/php-code-coverage": "dev-4.0-dev as 4.0.4"
    },
    "minimum-stability": "dev",
    "prefer-stable": true
}

This has things working for me with PHPUnit 5.7.
