2、maven笔记(二):编写测试代码

1.(接上一篇笔记maven笔记(一):构建项目)在E:mvnsrc下新建目录test,在test下新建"comzmpmvnhelloworldHelloWorldTest.java";

HelloWorldTest.java代码如下:

package com.zmp.mvn.helloworld;

import static org.junit.Assert.assertEquals;
import org.junit.Test;

public class HelloWorldTest {
    @Test
    public void testSayHello() {
        HelloWorld helloWorld = new HelloWorld();
        String result = helloWorld.sayHello();
        assertEquals("Hello Maven", result);
    }
}

2. pom.xml文件内容如下:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org./POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmi:schemaLocation="http://maven.apache.org/POM/4.0.0
    http://maven.apache.org/maven-v4_0_0.xsd">

    <modelVersion>4.0.0</modelVersion>
    <groupId>com.zmp.mvn</groupId>
    <artifactId>hello-world</artifactId>
    <version>1.0-SNAPSHOT</version>
    <name>MAVEN HELLO WORLD PROJECT</name>

    <!-- junit测试依赖项 -->
    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.7</version>
            <scope>test</scope>
        </dependency>
    </dependencies>
</project>

3.测试成功,输出信息如下:

4.过程中出现的问题:

• 刚开始一直报错,错误原因:找不到类org.junit,而在本地库中已经下载了junit相关的依赖jar包和pom文件,后来翻看教程,由于试测试类代码跟主代码分开,放在test下,而刚开始没有放在test,junit扫描不到(<scope>test</scope>)下,所以报出问题;
