我能'；无法让JUnit在easy Java示例上工作

我无法让这个JUnit测试在我正在处理的这个简单Java示例上运行。它在Eclipse内部工作，但不从命令行工作。。。mvn测试

以下是我的测试代码：

import junit.framework.Assert;
import org.junit.Test;
import org.runnablejar.TestJAR.App;


public class TestApp {
    @Test
    public void testPrintHelloWorld() {

        Assert.assertEquals(App.getHelloWorld(), "Hello Worl");

    }
}

以下是我的测试输出：
