PHPUnit is not producing its clover coverage report

Question

Although phpunit supports the --coverage-clover [file] argument, it seems to be doing nothing.

I have Jenkins running on this server with the clover coverage plugin for php.

Here's my output:

> phpunit --coverage-clover coverage.xml
................................                                  32 / 32 (100%)

Time: 745 ms, Memory: 16.75Mb

> ls -l
(coverage.xml is not present)

I'm looking to find out why the clover XML file is not being generated at all, with no error message. Even using the --debug flag produces nothing related to the clover report.

Version information:

> phpunit --version
PHPUnit 5.0.5 by Sebastian Bergmann and contributors.

This is my PHPUnit XML File:

<phpunit bootstrap="tests/bootstrap.php">
    <testsuites>
        <testsuite name="tests/suite">
            <directory>tests/suite</directory>
        </testsuite>
    </testsuites>
</‌​phpunit>

It seems like you didn't define a whitelist. Without any whitelist, no coverage data will be produced in PHPUnit 5. Try something like:

<phpunit bootstrap="./test/bootstrap.php" colors="true">
    <testsuites>
        <testsuite name="Tests">
            <directory>./test</directory>
        </testsuite>
    </testsuites>
    <filter>
        <whitelist addUncoveredFilesFromWhitelist="true">
            <directory>./lib</directory>
        </whitelist>
    </filter>
</phpunit>
