E02_HttpRunner斷言：斷言類型清單

E02_HttpRunner斷言：斷言類型清單

在 comparators.py 檔案中，定義了可以使用的斷言類型：

1. equals： 是否相等
2. less_than： 小于
3. less_than_or_equals： 小于等于
4. greater_than： 大于
5. greater_than_or_equals： 大于等于
6. not_equals： 不等于
7. string_equals： 字元串相等
8. length_equals： 長度相等
9. length_greater_than： 長度大于
10. length_greater_than_or_equals： 長度大于等于
11. length_less_than： 長度小于
12. length_less_than_or_equals： 長度小于等于
13. contains： 預期結果是否被包含在實際結果中
14. contained_by： 實際結果是否被包含在預期結果中
15. type_match： 類型是否比對
16. regex_match： 正規表達式是否比對
17. startswith： 字元串是否以什麼開頭
18. endswith： 字元串是否以什麼結尾

以通路百度首頁舉例（其中斷言全部通過）：

- config:
    name: TestCase

- test:
    name: TestStep -1
    request: 
      url: https://www.baidu.com/
      method: GET
      headers:
        User-Agent: 'ozilla/5.0 (Windows NT 6.1; Win64; x64; rv:65.0) Gecko/20100101 Firefox/65.0'

    validate:
        # 斷言: 是否相等， 傳回響應狀态碼是否為200
        - equals: [status_code, 200]

        # 斷言： 是否包含， 響應實體中是否包含 “title” 字元串
        - contains: [content, title]

        # 斷言： 是否以指定字元串開頭， 響應實體是否以“<!DOCTYPE”字元串開頭
        - startswith: [body, <!DOCTYPE]

        # 斷言： 是否大于， 響應頭域數量是否大于 10 個
        - length_greater_than: [headers, 10]

        # 斷言： 是否類型比對， 響應實體類型是否為“str”字元串類型
        - type_match: [content, str]
