今天小编就为大家分享一篇关于spring boot使用Junit进行测试,小编觉得内容挺不错的,现在分享给大家,具有很好的参考价值,需要的朋友一起跟随小编来看看吧
使用junit或者testng可以进行单体测试,这篇文章简单说明一下如何在spring boot的项目中使用junit进行单体测试。
pom设定
pom中需要添加spring-boot-starter-test<dependency>
<groupid>org.springframework.boot</groupid>
<artifactid>spring-boot-starter-test</artifactid>
<scope>test</scope>
</dependency> 确认依赖
使用java进行unit测试至少需要junit之类的测试框架,另外spring boot相关的测试还应该有一些mock相关的依赖,这个spring-boot-starter-test到底包含什么,可以使用maven dependency来进行确认一下。使用命令:mvn dependency:tree 结果信息:[info] --- maven-dependency-plugin:3.0.2:tree (default-cli) @ springbootdemo ---

创建测试目录
根据惯例创建测试目录如下:liumiaocn:src liumiao$ ls
main test
liumiaocn:src liumiao$ find . -type d
.
./test
./test/java
./test/java/com
./test/java/com/liumiaocn
./test/java/com/liumiaocn/springbootdemo
./main
./main/resources
./main/java
./main/java/com
./main/java/com/liumiaocn
./main/java/com/liumiaocn/springbootdemo
liumiaocn:src liumiao$ 创建测试用例
代码示例liumiaocn:src liumiao$ cat ./test/java/com/liumiaocn/springbootdemo/springbootdemoapplicationtests.java
package com.liumiaocn.springbootdemo;
import org.junit.test;
import org.junit.runner.runwith;
import org.springframework.boot.test.context.springboottest;
import org.springframework.test.context.junit4.springrunner;
@runwith(springrunner.class)
@springboottest
public class springbootdemoapplicationtests {
@test
public void contextloads() {
}
}
liumiaocn:src liumiao$ 代码说明
- coc:根据惯例进行定义测试类的名称
- springboottest注解:springboottest是1.4之后引入的一个注解,使得springboot的测试变得更加方便
- runwith注解:使用了此注解的情况下,junit会调用runwith中所指定的类。不同的框架提供相应的runner用于测试,比如junit自己的junit4.class,在比如spring的springjunit4classrunner或者springrunner,都可与之结合使用。
- test注解:junit的常用注解之一,用于定义测试方法,不再赘述。
执行测试命令: mvn test 部分执行内容如下:[info] results:
[info]
[info] tests run: 1, failures: 0, errors: 0, skipped: 0 在实施的结果中可以看到运行起来的测试用例为1个,没有失败/跳过/出错的。
小结
通过spring-boot-starter-test的引入,在springboot中已经做好所有单元测试的准备,根据惯例的方式设定测试目录和文件名称,结合使用springboottest等注解,可以使用junit对springboot的应用进行测试。最后使用mvn test即可运行相关的测试用例并可确认结果,后面将会进一步说明如何与sonarqube以及jacoco等进行结合确认代码扫描等。
