使用机器人框架的python测试

Question

有没有人有一个使用 Robot Framework 测试 python 程序的好例子。

我正在尝试使用 --test 参数运行我的 python 程序 (chaptermarkers.py) 并检查结果。

传递论点是谷歌搜索 2 天的奥德赛。

[文件：common_resourses.robot]

*** Settings ***
Library  OperatingSystem

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

*** Keywords ***
# TODO

[测试用例：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}

无论我如何尝试在程序之后放置一些东西，我都会收到目录丢失的错误。

Answer 1

我注意到的一些事情：

1. 变量部分的${test} 和--test 之间至少需要有两个空格。你只提供了一个。在Run Process 行中相同，exec 和argument 之间应该至少有两个空格。规则是 RF 使用两个空格作为分隔符。
2. 您的测试名称是缩进的。 RF 将其解释为关键字调用，这是出乎意料的。它应该从行首开始，没有缩进
3. 文件丢失错误看起来很奇怪，我不知道原因。该文件是 RF 库的一部分，如果您正确安装了 RF，它应该在那里。建议你启动一个新的虚拟环境，如果不是太复杂的话再试一次。

附：仅供参考，所有 RF 内置库都可以在这里找到： https://robotframework.org/#libraries.
