Postman + newman + jenkins 的API自动化测试应用

一、环境配置

Postman

postman 的具体使用可以参考另外一篇文章：postman 做接口测试之学习笔记

Newman

第一步，安装nodejs。 
第二步，在nodejs命令行安装newman，即命令行输入如下命令：

npm install -g newman

jenkins

去官网（https://jenkins.io/index.html）下载jenkins

二、Postman + Newman + jenkins 的使用

1. 在postman中导出testcase 文件夹（即存各个接口的collection文件夹）和设置的环境变量文件。

如下所示，导出来的是个json 格式的文件

2. jenkins配置

注意：如果是安装在本地的Jenkins，要将jenkins开启，切换到jenkins.war 的路径下， 执行 java -jar jenkins.war 则可以开启了。

在jenkins上配置如下图，这个路径就是上面通过postman导出文件的路径。

剩下的就是jenkins的常规操作了，比如设置好邮箱后点击立即构建或者设置多久构建一次，这样自动化就跑起来了，等待自动化测试结束后我们就可以收到测试成功或者失败的测试报告邮件了（依赖于设置)。

通过上面这些步骤即可完成基于postman和Jenkins的自动化接口测试。

Newman的使用：

    -L, --recurseLimit [limit]      Do not run recursive resolution more than [limit] times. Default = . Using  will prevent any variable resolution

  Newman is a command-line collection runner for Postman. You must specify a collection file or a collection URL to run newman

  A collection file or URL is mandatory
  Examples:

    newman -c POSTMAN_COLLECTION
    newman -u POSTMAN_COLLECTION -e POSTMAN_ENVIRONMENT
    newman -c POSTMAN_COLLECTION -f SAMPLE_FOLDER
