我刚刚开始使用maven,我无法弄清楚如何解决我遇到的问题。似乎我的java文件已经编译并且测试开始但没有显示结果。

Demo.java:

package tutorial2;

public class Demo {

public boolean getBool(){
    return false;
}

}

TestDemo.java:

package tutorial2;

import static org.junit.Assert.*;

import org.junit.Test;

public class TestDemo {

@Test
public void shouldBe(){
    Demo demo = new Demo();
    assertTrue(demo.getBool());
}

}

的pom.xml:

            </plugin>
        </plugins>

</project

我在控制台上得到这个:

解决:

我自己解决了问题。未正确配置xml文件中的依赖项。 junit依赖的版本是错误的,所以它不能由maven运行。

提醒:

您应该始终通过“插入依赖项”菜单添加依赖项。当光标位于xml文件中的<dependency></dependency>之间时,可以使用快捷键“crtl”+“space”显示它。当您在“选择依赖关系”菜单中,在“输入...”文本框中输入“junit”并选择您的junit版本。单击“确定”后,将自动添加依赖项。这有助于避免手动输入错误版本的问题。

默认情况下,Surefire(在mvn test期间运行的插件)会查找以target/test-classes(从src/test/java编译,可能是其他地方编译)的类,这些类以Test结尾}。您的班级名称为TestDemo,不会以Test结尾,也不会被投放。可以将其重命名为DemoTest(最好),或者在<plugins>中手动配置Surefire(当您使用具有备用命名约定的框架时,例如Spock&#39; {{1 }})。

根据maven文档avalible on

  

默认情况下,Surefire插件会自动包含所有测试   具有以下通配符模式的类:

     

“/ Test * .java” - 包括其所有子目录和所有Java   以“Test”开头的文件名。 “/* Test.java” - 包括所有   它的子目录和所有以“Test”结尾的Java文件名。   “/* TestCase.java” - 包括其所有子目录和所有Java   以“TestCase”结尾的文件名。
