HttpRunner接口自动化测试框架--4.参数化操作（parameters）

从 2.0.0 版本开始，HttpRunner 不再支持在测试用例文件中进行参数化配置；参数化的功能需要在 testsuite 中实现。如需实现数据驱动机制，需要创建一个 testsuite，在 testsuite 中引用测试用例，并定义参数化配置。

这是一个测试套件文件格式：

 如需对某测试用例（testcase）实现参数化数据驱动，需要使用 parameters 关键字，定义参数名称并指定数据源取值方式。

参数名称的定义分为两种情况：独立参数单独进行定义；多个参数具有关联性的参数需要将其定义在一起，采用短横线（-）进行连接。

数据源指定支持三种方式：

1.在 YAML/JSON 中直接指定参数列表：该种方式最为简单易用，适合参数列表比较小的情况

2.通过内置的 parameterize（可简写为P）函数引用 CSV 文件：该种方式需要准备 CSV 数据文件，适合数据量比较大的情况

3.调用 debugtalk.py 中自定义的函数生成参数列表：该种方式最为灵活，可通过自定义 Python 函数实现任意场景的数据驱动机　　         制，当需要动态生成参数列表时也需要选择该种方式。

参数配置详解

1.独立参数 & 直接指定参数列表

3.独立参数 & 引用 CSV 文件

对于 CSV 数据文件，需要遵循如下几项约定的规则：

1.CSV 文件中的第一行必须为参数名称，从第二行开始为参数值，每个（组）值占一行；

2.若同一个 CSV 文件中具有多个参数，则参数名称和数值的间隔符需实用英文逗号；

独立参数和关联参数 在自定义函数中是一样的，需要注意的是，在自定义函数中，生成的参数列表必须为 list of dict 的数据结构，该设计主要是为了与 CSV 文件的处理机制保持一致。

7.如果想要实现多个参数的随机组合可以在parameters中指定多个参数，系统会按照笛卡尔积的概念执行行。

例如：

组合结果为：

 

8.注意：系统内置函数实现参数化读取的是CSV文件，而CSV文件是一个纯文本文件，如果在断言时遇到断言int类型则断言失败
