記錄&生成測試用例

捕獲HTTP請求和響應

在編寫測試用例之前，我們應該瞭解API的細節。使用像Charles proxy這樣的web除錯代理工具來捕獲HTTP流量是一個不錯的選擇。

例如，下面的圖片展示了post表單資料到postman-echo.com。

將會話匯出到HAR檔案

然後我們可以選擇捕獲的請求和響應，並將會話匯出到HTTP歸檔(.har)檔案。

用har2case生成testcase

獲得HAR檔案後，可以使用內建命令har2case將其轉換為HttpRunner 測試用例。

help

$ 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testcase (pytest)

由於HttpRunner 3.0.7, har2case在預設情況下會將HAR檔案轉換為pytest，因此非常建議用pytest格式編寫和維護測試用例，而不是以前的YAML/JSON格式。
