什么是接口测试？怎样做接口测试？
袁清波i 于 2018-08-20 11:17:31 发布 184171 收藏 3326
1.什么是接口？
2.接口都有哪些类型？
接口的分类：1.webservice接口 2.http api接口
3.接口的本质及其工作原理是什么？
4.什么是接口测试？
5.问什么要做接口测试？
6.怎样做接口测试？
7.接口测测试点是什么？
问题1.1、后端接口都测试什么？
问题2、后端接口测试一遍 ，前端也测试一遍，是不是重复测试了？
从上面这两张图对比可以看出，两个测试活动中相同的部分有功能测试、边界分析测试和性能测试，其它部分由于各自特性或关注点不同需要进行特殊的测试，在此不做讨论。接下来我们针对以上三部分相同的内容再进行分析：
1、基本功能测试：
2、边界分析测试：
3、性能测试：
3、接口测试持续集成：
4、接口测试质量评估标准：
8.接口测试都要掌握哪些知识？
如何学这些技能？
如何获取接口相关信息？
接口文档八要素：
封面：封面最好是本公司规定的封面，有logo，内容标题，版本号，公司名称，文档产生日期；
修订历史：表格形式较好些，包括：版本、修订说明、修订日期、修订人、审核时间审核人等；
接口信息：接口调用方式，常用的GET/POST方式，接口地址；
功能描述：简洁清晰的描述接口功能，比如：接口获取的信息不包括哪些；
接口参数说明：每个参数都要和实际中调用的一样，包括大小写；参数的含义言简意赅的说明，格式，是string 还是int IQ Option 简介 还是long等格式；
返回值说明：
调用限制，安全方面：
9.其他相关知识？
get请求，post请求的区别：
1、GET使用URL或Cookie传参。而POST将数据放在BODY中。
2、GET的URL会有长度上的限制，则POST的数据则可以非常大。
3、POST比GET安全，因为数据在地址栏上不可见。
4、一般get请求用来获取数据，post请求用来发送数据。
其实上面这几点，只有最后一点说的是比较靠谱的，第一点post请求也可以把数据放到url里面，get请求其实也没长度限制，post请求看起来参数是隐式的，稍微安全那么一些些，但是那只是对于小白用户来说的，就算post请求，你通过抓包也是可以抓到参数的。（唯一区别就是这一点，上面3点区别都是不准确的）
http状态码：
1、200 2开头的都表示这个请求发送成功，最常见的就是200，就代表这个请求是ok的，服务器也返回了。
2、300 3开头的代表重定向，最常见的是302，把这个请求重定向到别的地方了。
3、400 400代表客户端发送的请求有语法错误，401代表访问的页面没有授权，403表示没有权限访问这个页面，404代表没有这个页面。
4、500 5开头的代表服务器有异常，500代表服务器内部异常，504代表服务器端超时，没返回结果。
