What are some common errors in PHP unit testing configurations that could lead to a 0% code coverage result?

One common error in PHP unit testing configurations that could lead to a 0% code coverage result is not properly specifying the source files or directories to be tested. This can happen if the PHPUnit configuration file does not include the correct paths to the files that need to be tested. To solve this issue, ensure that the `phpunit.xml` file or configuration settings include the correct paths to the source files.

&lt;!-- phpunit.xml --&gt;
&lt;phpunit&gt;
    &lt;testsuites&gt;
        &lt;testsuite name=&quot;MyTestSuite&quot;&gt;
            &lt;directory&gt;tests&lt;/directory&gt;
        &lt;/testsuite&gt;
    &lt;/testsuites&gt;
    &lt;filter&gt;
        &lt;whitelist addUncoveredFilesFromWhitelist=&quot;true&quot;&gt;
            &lt;directory suffix=&quot;.php&quot;&gt;src&lt;/directory&gt;
        &lt;/whitelist&gt;
    &lt;/filter&gt;
&lt;/phpunit&gt;
