Maven命令测试

Maven教程 - Maven命令测试

当使用Maven创建一个项目时，它会创建一个带main方法的类测试用例。

AppTest.java的内容

package com.java2s.ide;

import junit.framework.Test;
import junit.framework.TestCase;
import junit.framework.TestSuite;

/**
 * Unit test for simple App.
 */
public class AppTest 
    extends TestCase
{
    /**
     * Create the test case
     *
     * @param testName name of the test case
     */
    public AppTest( String testName )
    {
        super( testName );
    }

    /**
     * @return the suite of tests being tested
     */
    public static Test suite()
    {
        return new TestSuite( AppTest.class );
    }

    /**
     * Rigourous Test :-)
     */
    public void testApp()
    {
        assertTrue( true );
    }
}

要通过Maven运行单元测试，请发出以下命令:

c:\mvn_test\xmlFileEditor>mvn test

上面的代码生成以下结果。

Maven教程 - Maven命令测试...

我们可以添加更多的测试用例到测试目录。 首先我们添加两个静态方法App.java。 两个dummy方法只是返回String常量。 我们要用这些方法来说明如何向Maven项目添加测试用例。

package com.java2s.ide;
public class App {
  public static void main(String[] args) {
     System.out.println(getHelloWorld());
  }
  public static String getHelloWorld() {
    return "Hello World";
  }
  public static String getHelloWorld2() {
    return "Hello World 2";
  }
}

我们可以通过向 test 文件夹中添加一个新类来对getHelloWorld()方法进行单元测试。

package com.java2s.ide;
import junit.framework.Assert;

import junit.framework.Test;
import junit.framework.TestCase;
import junit.framework.TestSuite;
public class TestApp1 {
 
  public void testPrintHelloWorld() {
    Assert.assertEquals(App.getHelloWorld(), "Hello World");
  }
}

以下代码显示如何为getHelloWorld2()方法添加另一个单元测试。

package com.java2s.ide; 
import junit.framework.Assert;

import junit.framework.Test;
import junit.framework.TestCase;
import junit.framework.TestSuite;
public class TestApp2 {

  public void testPrintHelloWorld2() {
    Assert.assertEquals(App.getHelloWorld2(), "Hello World 2");
  }
}

运行测试用例

添加这两个测试用例后，我们可以再次运行下面的Maven命令用于测试。

c:\mvn_test\xmlFileEditor>mvn test

上面的代码生成以下结果。

c:\mvn_test\xmlFileEditor>mvn clean test

运行测试用例...

上面的命令运行所有测试用例

要运行单个测试( TestApp1 )，请发出以下命令:

mvn -Dtest=TestApp1 test

上述命令生成以下结果。

c:\mvn_test\xmlFileEditor>mvn -Dtest=TestApp1 test
