Maven wird keine Tests ausführen

Question

Wenn mvn test ausgeführt wird, werden nicht alle Testklassen ausgeführt. Wenn ich explizit eine Klasse durch Hinzufügen von -Dtest = PropertyTests zur Verfügung stelle, werden die Tests ausgeführt.

Hier ist meine pom.xml:

<?xml version="1.0" encoding="UTF-8"?> 
<project xmlns="http://maven.apache.org/POM/4.0.0" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

     <org.slf4j-version>1.6.6</org.slf4j-version> 
     <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 
    </properties> 

    <dependencies>

     </dependency>

     </dependency> 

    </dependencies> 

    <build> 

     <plugins> 

      <plugin> 
       <groupId>org.apache.maven.plugins</groupId> 
       <artifactId>maven-compiler-plugin</artifactId> 
       <configuration> 
        <source>${java-version}</source> 
        <target>${java-version}</target> 
       </configuration> 
      </plugin> 

     </plugins> 

    </build> 

</project> 

Warum Maven werden die Tests automatisch nicht ausgeführt? Habe ich etwas verpasst?

UPDATE

Beispiel Test (Klasse ist 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 Ausgabe auf mvn test:

Answer 1

Sie müssen das Maven-Surefire-Plugin hinzufügen, um die Tests auszuführen. Die Konfiguration kann hier gefunden werden: http://maven.apache.org/surefire/maven-surefire-plugin/examples/inclusion-exclusion.html

UPDATE:

Hier ist eine Konfiguration, die ich mit specs/junit verwendet haben.

  <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> 

UPDATE 2:

Die Namenskonvention ist Test so ändern Property zu PropertyTest.
