1 关于检查点
- 其实就是断言，那什么是断言？之前我们对几个接口进行了请求，并设置了查看结果树，我们人工检查它是对的。那如果数据量多或者做性能测试的时候，不可能人工挨个看，我们可以通过设置断言组件来进行结果或者响应检查；
2 断言
- 断言组件是通过获取服务器响应数据，然后根据断言规则去匹配这想响应数据；
- 如果匹配不到，出现异常时，JMeter就会断定这个事务失败；
- 查看结果树中看到请求失败的事务的请求名称是红色字体；
- 以下以响应断言组件为例来说明断言的一些应用；
- 实际应用中响应断言可满足80%以上的验证问题。
3 响应断言（Response Assertion）
3.1 参数说明
| 参数 | 说明 |
|---|---|
| 名称 | 随意设置具有业务意义即可 |
| 注释 | 随意设置，可为空 |
Main sample and sub-samples |
匹配范围为当前父取样器覆盖至子取样器 |
Main sample only |
匹配当前父取样器 |
Sub-samples only |
匹配子取样器 |
JMeter Variable |
对JMeter变量值进行匹配 |
| 响应文本 | 响应服务器返回的内容，除去Header部分 |
| 响应代码 | 匹配响应代码，如200 |
| 响应信息 | 匹配响应信息，如“成功” |
| 响应头 | 匹配响应中的头信息 |
| 请求头 | 匹配请求中的头信息 |
| URL样本 | 匹配URL链接 |
| 文档（文本） | 对文档内容匹配 |
| 忽略状态 | 第一个响应断言失败可忽略结果，进行下一个断言 |
| 请求数据 | 匹配请求数据 |
| 包括 | 响应内容匹配内容代表响应成功，支持正则 |
| 匹配 | 响应内容要完全匹配需要匹配的内容，大小写不敏感，支持正则 |
| 相等 | 响应内容要完全等于需要匹配的内容 ，大小写不敏感，支持正则 |
| 字符串 | 响应内容匹配需要匹配的内容代表响应成功 ，大小写敏感，需要匹配的内容为字符串非正则 |
| 否 | 降低匹配级别 |
| 或者 | 有一个通过则整个断言通过 |
| 测试模式 | 要匹配的字符串或者正则表达式 |
| 自定义失败信息 | 如字面意思 |
4 实例说明
- 在JMeter笔记9 | JMeter参数化的基础上加上响应断言即可；
- 即在“1-获取token”请求加上响应断言；
- 在“1-1-获取用户列表”请求加上响应断言。
4.1 获取token接口加响应断言
- 添加【响应断言】，设置参数如下：
- 说明：即通过响应代码201来匹配响应是否成功。
4.2 获取用户列表接口加响应断言
- 添加【响应断言】，设置参数如下：
- 说明：通过设置测试模式
"page":1，看响应文本中是否包含"page":1来判断是否成功。
