录制和生成测试用例

抓取http请求和响应

在我们编写测试用例之前，我们应该知道API的详细信息，我们可以使用类似与Fiddle，Charles这样的抓包工具来抓取http请求

下面，我将使用一个测试环境

我们可以选择需要的请求，导出成.har的格式

使用har2case生成测试用例

获取 HAR 文件后，可以使用内置命令将其转换为 httpRunner 测试用例

har2case帮助

har2case -h
usage: har2case har2case [-h] [-2y] [-2j] [--filter FILTER]
                         [--exclude EXCLUDE]
                         [har_source_file]
 
positional arguments:
  har_source_file       Specify HAR source file
 
optional arguments:
  -h, --help            show this help message and exit
  -2y, --to-yml, --to-yaml
                        Convert to YAML format, if not specified, convert to
                        pytest format by default.
  -2j, --to-json        Convert to JSON format, if not specified, convert to
                        pytest format by default.
  --filter FILTER       Specify filter keyword, only url include filter string
                        will be converted.
  --exclude EXCLUDE     Specify exclude keyword, url that includes exclude
                        string will be ignored, multiple keywords can be
                        joined with '|'

生成测试用例

在3.0中，由于httpRunner默认会将HAR文件转成pytest，建议使用pytest，而不是之前的yaml、json格式

har2case test.har

生成的pytest文件是如下标准的pytest文件，它可以直接运行：

# NOTE: Generated By HttpRunner v3.1.3
# FROM: test.har
 
from httprunner import HttpRunner, Config, Step, RunRequest, RunTestCase
class TestCaseTest(HttpRunner):
    config = Config("testcase description").verify(False)
    teststeps = [
        Step(
            RunRequest("/YYDZPY/login")
            .post("http://192.168.3.70:8070/YYDZPY/login")

            )
            .with_cookies(**{"JSESSIONID": "0E40D65F4C701A93621D2BE023A309C1"})
            .with_json({"XTZH": "U1lTVEVN", "YHMM": "B/RGSNco4fpCWqdYQ3qSNg=="})

            .assert_equal("body.msg", "登录成功！")
            .assert_equal("body.errormsg", "用户未设置所属部门,部分功能会受影响，请联系管理员设置")
        ),
    ]
 
 
if __name__ == "__main__":
    TestCaseTest().test_start()

它可以使用命令或本机命令运行

hrun pytest

测试用例的组织形式：

在httpRunner中，测试用例的组织形式一共有三种：分别是。json，yaml和pytest

如何生成这些json、yaml、pytest文件？

第一步：

抓包

第二步：

把请求包保存为har格式

第三步：

使用命令生成

可以使用 -2y 来将 har文件生成yaml格式的用例

可以使用 -2j 来将 har文件生成json格式的用例

例如：现有有一个test.har的文件

可以使用 har2case test.har -2y 命令 生成yaml格式的用例

har2case test.har -2y
$ har2case har/postman-echo-post-form.har -2j
2020-06-15 15:32:02.955 | INFO     | httprunner.ext.har2case.core:gen_testcase:332 - Start to generate testcase from har/postman-echo-post-form.har
2020-06-15 15:32:02.955 | INFO     | httprunner.ext.har2case.core:_make_testcase:323 - Extract info from HAR file and prepare for testcase.
2020-06-15 15:32:02.958 | INFO     | httprunner.ext.har2case.utils:dump_json:122 - dump testcase to JSON format.
2020-06-15 15:32:02.959 | INFO     | httprunner.ext.har2case.utils:dump_json:131 - Generate JSON testcase successfully: har/postman-echo-post-form.json

可以使用 har2case test.har -2j 命令生成json格式的用例

har2case test.har -2j
$ hrun har/postman-echo-post-form.json

如果，你使用的3.0的版本，建议以新使用pytest格式
