有效的接口测试可以为我们的接口质量保驾护航。Karate的中文翻译是空手道，是一款接口测试框架，BDD类型，非程序员也能上手。
你能学到什么
你可以通过这篇教程学会如何通过jar包方式使用Karate进行接口测试
你需要什么
- 大约10分钟
- JDK 1.8+
环境准备
本篇教程通过命令行执行jar文件的方式来进行接口测试编写。
首先创建工作目录，进入这个目录
$ mkdir KarateTest
$ cd KarateTest
下载执行文件。
通过https://dl.bintray.com/ptrthomas/karate/下载最新jar包，下载后保存到项目根目录中，现在我们的项目有了第一个文件，结构如下：
$ tree
.
└── karate-0.9.4.jar
0 directories, 1 file
编写第一个接口用例文件HttpbinGet.feature，内容如下
Feature: Httbin.org get method test
Scenario: Get should be ok
Given url 'http://httpbin.org/get'
When method get
Then status 200
添加完用例后目录结构为
$ tree
.
├── HttpbinGet.feature
└── karate-0.9.4.jar
0 directories, 2 files
执行用例
$ java -jar karate-0.9.4.jar HttpbinGet.feature
