使用Maven运行单元测试

要通过Maven运行单元测试，发出此命令：

mvn test

这会在你的项目中运行整个单元测试。

案例学习

创建两个单元测试，并通过 Maven 的运行它。参见一个简单的 Java 测试类：

package com.bjpowernode.core;

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";

	}
}

Unit Test 1

单元测试为getHelloWorld()方法。

package com.bjpowernode.core;

import junit.framework.Assert;
import org.junit.Test;

public class TestApp1 {

	@Test
	public void testPrintHelloWorld() {

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

	}

}

Unit Test 2

单元测试为getHelloWorld2()方法。

package com.bjpowernode.core;

import junit.framework.Assert;
import org.junit.Test;

public class TestApp2 {

	@Test
	public void testPrintHelloWorld2() {

		Assert.assertEquals(App.getHelloWorld2(), "Hello World 2");

	}

}

运行单元测试

使用Maven运行单元测试看见下面的例子。

示例1：运行整个单元测试(TestApp1和TestApp2)，发出以下命令：

mvn test

示例2：为了运行单个测试(TestApp1)，发出此命令：

mvn -Dtest=TestApp1 test [INFO] --- maven-compiler-plugin:3.1:compile (default-compile) @ bjpowernode-core --

示例:3

为了运行单个测试(TestApp2)，发出此命令：

mvn -Dtest=TestApp2 test
