robotframework - python tests using robot framework

Does anyone have a good example of testing a python program using Robot Framework.

I am trying to run my python program (chaptermarkers.py) with an argument of --test and checking the results.

Passing the argument has been an odyssey of google searches for 2 days.

[file: common_resourses.robot]

*** Settings ***
Library  OperatingSystem

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

*** Keywords ***
# TODO

[Test Cases: file: 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}

No matter how I try to put something after the program, I get an error of directory missing.

[Crazy unusable error messages]

A few things I noticed:

  1. There needs to be at least two spaces between ${test} and --test in your variables section. You provided only one. The same in the Run Process line, there should be at least two spaces between exec and argument. The rule is that RF uses two spaces as delimiter.
  2. Your test name is indented. RF inteprets it as a keyword calling which is unexpected. It should start from the begining of the line without indent
  3. The file missing error looks weired and I don't know the reason. The file is part of RF library and if you installed RF correctly, it should be there. I suggest that you start a new virtual environment and try again if it's not too complex.

P.S. Just FYI, all RF buil-in libraries can be found here: https://robotframework.org/#libraries.
