httprunner學習5-參數化與數據驅動

前言

參數化是自動化測試離不開的話題，httprunner里面只要把上一篇聲明變量學會了，參數化也就自然會了。
不同的地方在於聲明變量時對應值只有一個，參數化是多個值，存放在list里面。
httprunner==1.5.8

登錄參數化

先准備測試數據，准備四組登錄用的賬號和密碼，賬號為test1,test2,test3,test4,密碼統一設置為123456。

參數user賬號數據，設置對應的值 ["test1", "test2", "test3", "test4"],定義單個參數用variables，定義參數化用parameters

    parameters:
        - user: ["test1", "test2", "test3", "test4"]  # 參數化
        - psw: ["123456"]

如果參數化里面的數據只有一個，比如psw對應的值只有一個，使用variables和parameters對應都可以

    parameters:
        - user: ["test1", "test2", "test3", "test4"]  # 參數化
    variables:
        psw: 123456

完整的test_parameters.yml腳本如下

- config:
    name: logincase
    parameters:
        - user: ["test1", "test2", "test3", "test4"]    # 參數化
        - psw: ["123456"]
- test:
    name: login case1
    request:
        url: http://127.0.0.1:8000/api/v1/login/
        method: POST
        headers:
            Content-Type: application/json
            User-Agent: python-requests/2.18.4
        json:
            username: $user               # 引用變量
            password: $psw
    extract:
        - token: content.token         # 提取token
    validate:
        - eq: [status_code, 200]
        - eq: [headers.Content-Type, application/json]
        - eq: [content.msg, login success!]
        - eq: [content.code, 0]

運行用例

運行用例，會自動生成四個測試用例

關聯參數

上面的案例多個賬號，密碼都是一樣的，如果密碼不一樣呢？上面的就行不通了，所以針對於一個賬號對應一個密碼，這種一一對應的關系，可以用關聯性的參數化

    parameters:
        - user-psw:
            - ["test1", "123456"]
            - ["test2", "123456"]
            - ["test3", "123456"]
            - ["test3", "123456"]

完整的測試用例test_param_psw.yml

# 上海悠悠，QQ交流群：750815713
- config:
    name: logincase
    parameters:
        - user-psw:
            - ["test1", "123456"]
            - ["test2", "123456"]
            - ["test3", "123456"]
            - ["test3", "123456"]
- test:
    name: login case1
    request:
        url: http://127.0.0.1:8000/api/v1/login/
        method: POST
        headers:
            Content-Type: application/json
            User-Agent: python-requests/2.18.4
        json:
            username: $user
            password: $psw
    extract:
        - token: content.token         # 提取token
    validate:
        - eq: [status_code, 200]
        - eq: [headers.Content-Type, application/json]
        - eq: [content.msg, login success!]
        - eq: [content.code, 0]

笛卡爾積組合

比如測試賬號有四種["test1", "test2", "test3", "test4"],密碼也有四種 ["123456", "123456", "123456", "123456"]
用笛卡爾積組合的話，就是4*4=16種組合

# 上海悠悠，QQ交流群：750815713
- config:
    name: logincase
    parameters:
        - user: ["test1", "test2", "test3", "test4"]
        - psw: ["123456", "123456", "123456", "123456"]

- test:
    name: login case1
    request:
        url: http://127.0.0.1:8000/api/v1/login/
        method: POST
        headers:
            Content-Type: application/json
            User-Agent: python-requests/2.18.4
        json:
            username: $user
            password: $psw
    extract:
        - token: content.token         # 提取token
    validate:
        - eq: [status_code, 200]
        - eq: [headers.Content-Type, application/json]
        - eq: [content.msg, login success!]
        - eq: [content.code, 0]

這樣運行會生成16組用例，很顯然，這種不適用與登錄-密碼一對一的情況。可以用在其它的測試場景
