Phpunit: Trying to generate code coverage report tells me: "No whitelist configured, no code coverage will be generated"

[alberto56]

According to the documentation "Chapter 11. Code Coverage Analysis":

By default, all source files that contain at least one line of code that has been executed (and only these files) are included in the code coverage report.

...

It is best practice to use a whitelist instead of the blacklist mentioned above.

I understand from this that whitelists are not compulsory. My phpunit.xml file thus does not reference any white- or blacklist:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit colors="true">
    <testsuites>
        <testsuite name="Application Test Suite">
            <directory>mycode/test/</directory>
        </testsuite>
    </testsuites>
</phpunit>

When I try to get code coverage, however, I get the error:

./vendor/bin/phpunit --version
PHPUnit 5.0.8 by Sebastian Bergmann and contributors.
./vendor/bin/phpunit --coverage-html coverage
Error:         No whitelist configured, no code coverage will be generated

I at first thought this was due to #1872, but that change is included in version 5.0.8, which I'm using.

How can I get phpunit to just generate code coverage for "all source files that contain at least one line of code that has been executed", as is described in the documentation?

It seems that the code which outputs this error would not run if the "whitelist" argument is set. I thought I could set it to empty by adding this to my xml file:

<filter>
  <whitelist processUncoveredFilesFromWhitelist="true">
  </whitelist>
</filter>

But I'm still getting the same output.

Thanks!

Just a note that this error can occur when XDebug is not loaded, as described in #347.

However, in my case XDebug seems to be loaded correctly:

$ php -ini|grep 'xdebug support'
xdebug support => enabled

No clue how #347 should be related here.

There was a bug in the documentation (https://github.com/sebastianbergmann/phpunit-documentation/issues/335) that has been fixed now.

Much appreciated @sebastianbergmann !

Thanks for the quick response, I am no longer getting this error.

Dear @sebastianbergmann
Should I update my phpunit version?
Which version that solved this bug?

Thank You.

@hierony94 @BorderCloud @luisgjb @diego3 You need to configure a whitelist in your phpunit.xml file, per this documentation.

had the same issue. solved it by ensuring 2 things

1. xdebug is installed and loaded in phpstorm.
