[holema]

Q	A
PHPUnit version	10.1.2
PHP version	8.2
Installation Method	Composer

Summary

I have two testsuits and one Testsuite is excluding a direcory with tests. The Testsuits are executed as expected but at the end of the tests I get the error that the configuration is not correct:

#phpunit.xml.dist
<?xml version="1.0" encoding="UTF-8"?>
<!-- https://phpunit.readthedocs.io/en/latest/configuration.html -->
<phpunit
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      <exclude>
        <directory>./tests/LDAP</directory>
      </exclude>
    </testsuite>
  </testsuites>
  <extensions>
    <bootstrap class="DAMA\DoctrineTestBundle\PHPUnit\PHPUnitExtension" />
  </extensions>
  <source>
    <include>
      <directory suffix=".php">src</directory>
    </include>
  </source>
</phpunit>

The Error

1) Test results may not be as expected because the XML configuration file did not pass validation:
  Line 26:
  - Element 'exclude': Element content is not allowed, because the type definition is simple.

The coresponding XSD which is downloaded from: https://schema.phpunit.de/10.1/phpunit.xsd:

<xs:complexType name="testSuiteType">
        <xs:sequence>
            <xs:choice minOccurs="0" maxOccurs="unbounded">
                <xs:group ref="testSuitePathGroup"/>
                <xs:element name="exclude" type="xs:string"/>
            </xs:choice>
        </xs:sequence>
        <xs:attribute name="name" type="xs:string" use="required"/>
    </xs:complexType>
    <xs:group name="testSuitePathGroup">
        <xs:sequence>
            <xs:choice minOccurs="0" maxOccurs="unbounded">
                <xs:element name="directory" type="testSuiteDirectoryType"/>
                <xs:element name="file" type="testSuiteFileType"/>
            </xs:choice>
        </xs:sequence>
    </xs:group>
    <xs:complexType name="testSuiteDirectoryType">
        <xs:simpleContent>
            <xs:extension base="xs:string">
                <xs:attribute type="xs:string" name="prefix" default=""/>
                <xs:attribute type="xs:string" name="suffix" default="Test.php"/>
                <xs:attributeGroup ref="phpVersionGroup"/>
            </xs:extension>
        </xs:simpleContent>
    </xs:complexType>

Current behavior

All Tests are successfull, but the test is failing in my pipeline, because the verification of the xml fails

How to reproduce

Use this config to exclude a directory

Expected behavior

No failure of the tests and a correct validation of the xml.
