PHPUnit warning - No filter is configured, code coverage will not be processed

Question

I'm trying to generate coverage html file with PHPUnit. I get a warning: 'No filter is configured, code coverage will not be processed' and coverage file isn't generated.

This is phpunit.xml file

<?xml version="1.0" encoding="UTF-8"?>
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" colors="true" xsi:noNamespaceSchemaLocation="https://schema.phpunit.de/9.3/phpunit.xsd">
  <testsuites>
    <testsuite name="Application Test Suite">
      <directory>./phpUnitTutorial</directory>
    </testsuite>
  </testsuites>
</phpunit>

Can anyone help?

Could be worth having a look at some of the other questions about code coverage to see what they use - https://mcmap.net/q/586948/-phpunit-code-coverage – Miscall

Answer 1

I suggest you use the configuration generator (phpunit --generate-configuration). It will ask you a couple of questions and then generate the right configuration for you.

Oh! That's real shame for me to admit that my coverage folder was created before asking question. I was looking for index.html file in root directory and I didn't notice that there was created new directory here. But thank You for your respond anyway. It's good to know this way, especially as I'm still beginner in PHPUnit. – Cordeliacordelie

Ok. After few tests (on generating coverage folder) I see that phpunit.xml needs not empty 'coverage' tag with specified valid source directory inside to generate coverage directory. Given solution generates this tag. – Cordeliacordelie

Doesn't really answer the question though, does it? Which bit was missing? That would have been the answer to the question. And then maybe a "hey did you know that if you use the configuration generator..." etc as a footnote. – Lumbago

Answer 2

I added the following to my PHPUnit 9.5 configuration file between the <phpunit> tags:

<coverage>
    <include>
        <directory suffix=".php">src</directory>
    </include>
</coverage>

As of PHPUnit 10.x it is:

<?xml version="1.0"?>
<phpunit
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="https://schema.phpunit.de/10.1/phpunit.xsd"
        bootstrap="bootstrap.php"
        colors="true"
        beStrictAboutOutputDuringTests="true"
        cacheDirectory=".phpunit.cache"
        requireCoverageMetadata="true"
>
    ...
    <source>
        <include>
            <directory>../../src</directory>
        </include>
    </source>
</phpunit>

Create a file called phpunit.xml, and fill it with the following.

<?xml version="1.0" encoding="UTF-8"?>
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="https://schema.phpunit.de/10.5/phpunit.xsd">
  <source>
    <include>
      <directory suffix=".php">src</directory>
    </include>
  </source>
</phpunit>

Replace "src" with the name of the folder that you want to be analyzed.

for people like me: I had changed the namespace, but PHPStorm had moved everything in the src/ directory to the root directory of the project. The tests still run, but when trying to generate coverage, I got that message.
