Maven 不会运行测试

Question

当运行mvn test 时，maven 不会运行所有的测试类。 当我通过添加 -Dtest=PropertyTests 明确提供类时，将运行测试。

这是我的 pom.xml：

<configuration>
    <includes>
        <include>**/*Spec.*</include>
        <include>**/*Test.*</include>
    </includes>
</configuration>

        <java-version>1.6</java-version>
        <org.slf4j-version>1.6.6</org.slf4j-version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

    <dependencies>

        </dependency>

        <!-- Test -->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.10</version>
            <scope>test</scope>
        </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>

为什么 maven 不会自动运行测试？我错过了什么吗？

示例测试（类在 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() );
    }
}

mvn test 上的 Maven 输出：

$ mvn test

您需要添加 maven surefire 插件来运行测试。配置可以在here找到。

这是我一直在使用 specs/junit 的配置。

<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>

命名约定是Test，所以把PropertyTests改成PropertyTest。
