使用Maven運(yùn)行單元測試

要通過Maven運(yùn)行單元測試，發(fā)出此命令：

mvn test

這會在你的項目中運(yùn)行整個單元測試。

案例學(xué)習(xí)

創(chuàng)建兩個單元測試，并通過 Maven 的運(yùn)行它。參見一個簡單的 Java 測試類：

package com.yiibai.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

單元測試為getHelloWorld()方法。

package com.yiibai.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

單元測試為getHelloWorld2()方法。

package com.yiibai.core;

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

public class TestApp2 {

	@Test
	public void testPrintHelloWorld2() {

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

	}

}

運(yùn)行單元測試

使用Maven運(yùn)行單元測試看見下面的例子。

示例 1
運(yùn)行整個單元測試(TestApp1和TestApp2)，發(fā)出以下命令：

mvn test

示例 2
為了運(yùn)行單個測試(TestApp1)，發(fā)出此命令：

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

示例 3
為了運(yùn)行單個測試(TestApp2)，發(fā)出此命令：

mvn -Dtest=TestApp2 test
