Maven won't run tests - maven

Question

When running mvn test maven won't run all Test Classes.
When I explicitly provide a class by adding -Dtest=PropertyTests the tests will be run.
Here's my pom.xml:
<configuration>
<includes>
<include>**/*Spec.*</include>
<include>**/*Test.*</include>
</includes>
</configuration>
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

Why maven won't run the tests automatically? Did I missed something?
Example test (Class is in src/test/java/com/example/PropertyTests.java):
public final class PropertyTests
{
#Test
public void testGetters()
{
Property property = new Property( "foo", "bar" );
Assert.assertEquals( "foo", property.getKey() );
Assert.assertEquals( "bar", property.getValue() );
}
}
Maven output on mvn test:
$ mvn test

You need to add the maven surefire plugin to run the tests. The configuration can be found here.
Here's a configuration that I've been using with specs/junit.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.8.1</version>
<configuration>
<includes>
<include>**/*Spec.*</include>
<include>**/*Test.*</include>
</includes>
</configuration>
</plugin>
The naming convention is Test, so change PropertyTests to PropertyTest.
