python 使用機器人框架進行測試

Question

有沒有人有一個使用機器人框架測試 python 程序的好例子。

我正在嘗試使用 --test 參數運行我的 python 程序（chaptermarkers.py）並檢查結果。

通過論點是谷歌搜索 2 天的奧德賽。

[文件：common_resourses.robot]

*** Settings ***
Library  OperatingSystem

*** Variables ***
${CHAPTERMARKERS_EXEC}  chaptermarkers
${LOG LEVEL}    DEBUG

*** Keywords ***
# TODO

[測試用例：文件：default_suite.robot]

*** Settings ***
Documentation       *Test Chapter Markers runs but has error in filename*
Metadata    Github  https://github.com/cbitterfield/chaptermarkers
Metadata    Version 1.0.0
Metadata    Executed At    ${HOST}


# External libraries imports
Library  Process
Library  String

Resource    common_resources.robot

*** Variables ***
${EXPECTED_MESSAGE}  Movie Filename
${REPORT FILE}  report.html
${LOG FILE}     logfile.html
${LOG LEVEL}    DEBUG
${OUTPUT DIR}   /Users/colin/IdeaProjects/chaptermarkers
${test} --test


*** Test Cases ***

    Scenerio test chaptermarkers run
        [Tags]    DEBUG
        [Documentation]     Verifies that chaptermarkers is executed well and without errors
        ${result}=  Run process     ${CHAPTERMARKERS_EXEC} ${test}
        Should Contain  ${result.stdout}    ${EXPECTED_MESSAGE}
        Should Be Empty     ${result.stderr}

無論我如何嘗試在程序之后放置一些東西，我都會收到目錄丟失的錯誤。

Answer 1

我注意到的幾件事：

1. 在您的變量部分中， ${test}和--test之間至少需要有兩個空格。 你只提供了一個。 在Run Process行中也是如此，exec 和 argument 之間應該至少有兩個空格。 規則是 RF 使用兩個空格作為分隔符。
2. 您的測試名稱是縮進的。 RF 將其解釋為關鍵字調用，這是出乎意料的。 它應該從行首開始，沒有縮進
3. 文件丟失錯誤看起來很奇怪，我不知道原因。 該文件是 RF 庫的一部分，如果您正確安裝了 RF，它應該在那里。 我建議你啟動一個新的虛擬環境，如果不是太復雜再試一次。

PS僅供參考，所有RF內置庫都可以在這里找到： https://robotframework.org/#libraries 。
