if else в Robot Framework

Введение

В этой статье вы можете изучить различные способы применения логических операторов в RobotFramework

Пример

*** Settings *** *** Test Cases *** Demo IF 1 == 1 Log To Console "One equals one" END

python -m robot .\demo.robot

==================================================================== Demo ==================================================================== Demo "One equals one" Demo | PASS | -------------------------------------------------------------------- Demo | PASS | 1 test, 1 passed, 0 failed ====================================================================

Небольшой пример для Robot Framework версии 4 и выше

*** Settings *** Documentation IF / ELSE IF / ELSE example using Robot Framework 4+. ... Generate a random number. ... Do if-else logic based on the generated number. ... Stop (pass) when the condition is met. *** Variables *** ${MAX_TRIES}= ${50} ${NUMBER_TO_PASS_ON}= 7 *** Test Cases *** IF ELSE Demo FOR ${i} IN RANGE ${MAX_TRIES} ${random}= Evaluate random.randint(0, 10) IF ${random} == ${NUMBER_TO_PASS_ON} Pass Execution "${random} == ${NUMBER_TO_PASS_ON}" ELSE IF ${random} > ${NUMBER_TO_PASS_ON} Log To Console Too high. ELSE Log To Console Too low. END END

python -m robot .\demo.robot

Пример для Robot Framework версии 3

*** Settings *** Documentation IF / ELSE IF / ELSE example using Robot Framework 3. ... Generate a random number. ... Do if-else logic based on the generated number. ...

Сравнение переменной со строкой

При сравнении переменных со строками нужно пользоваться кавычками

*** Settings *** *** Test Cases *** IF ELSE With Variables Compare With ABC ABC Compare With ABC www.devhops.ru *** Keywords *** Compare With ABC [Arguments] ${text} IF "${text}" == "ABC" Log To Console OK ELSE Log To Console Not ABC END

Либо

… *** Keywords *** Compare With ABC [Arguments] ${text} IF $text == "ABC" …

python -m robot .\demo.robot

============================================================================== Demo ============================================================================== IF ELSE With Variables OK .Not ABC IF ELSE With Variables | PASS | ------------------------------------------------------------------------------ Demo | PASS | 1 test, 1 passed, 0 failed ==============================================================================

Если не взять в кавычки ABC то будет ошибка

*** Keywords *** Compare With ABC [Arguments] ${text} IF "${text}" == ABC

============================================================================== IF ELSE With Variables | FAIL | Invalid IF condition: Evaluating expression '"ABC" == ABC' failed: NameError: name 'ABC' is not defined nor importable as module Variables in the original expression '"${text}" == ABC' were resolved before the expression was evaluated. Try using '$text == ABC' syntax to avoid that. See Evaluating Expressions appendix in Robot Framework User Guide for more details. ------------------------------------------------------------------------------ Demo | FAIL | 1 test, 0 passed, 1 failed ==============================================================================

Если не взять в кавычки ${text} то ошибка будет такой

*** Keywords *** Compare With ABC [Arguments] ${text} IF ${text} == "ABC"

============================================================================== IF ELSE With Variables | FAIL | Invalid IF condition: Evaluating expression 'ABC == "ABC"' failed: NameError: name 'ABC' is not defined nor importable as module Variables in the original expression '${text} == "ABC"' were resolved before the expression was evaluated. Try using '$text == "ABC"' syntax to avoid that. See Evaluating Expressions appendix in Robot Framework User Guide for more details. ------------------------------------------------------------------------------ Demo | FAIL | 1 test, 0 passed, 1 failed ==============================================================================

Сравнение переменной с bool

При сравнении с ${TRUE} и ${FALSE} строки нужно заключать в кавычки

*** Settings *** *** Test Cases *** IF ELSE With Bool [Template] Compare With Bool ${TRUE} ${FALSE} "www.heihei.ru" ${0} ${1} ${2} ${NONE} *** Keywords *** Compare With Bool [Arguments] ${val} IF ${val} == ${TRUE} Log To Console ${val} == True ELSE IF ${val} == ${FALSE} Log To Console ${val} == False ELSE Log To Console ${val} is neither equal to True nor to False END

============================================================================== IF ELSE With Bool True == True .False == False ."www.heihei.ru" is neither equal to True nor to False .0 == False .1 == True .2 is neither equal to True nor to False .None is neither equal to True nor to False IF ELSE With Bool | PASS | ------------------------------------------------------------------------------ Demo | PASS | 1 test, 1 passed, 0 failed ==============================================================================

Это полность соответсвует тому как это сравнение выполняется в Python

for value in [True, False, "www.heihei.ru", 0, 1, 2, None]: if value == True: print(f"{value} == True") elif value == False: print(f"{value} == False") else: print(f"{value} is neither equal to True nor to False")

True == True False == False www.heihei.ru is neither equal to True nor to False 0 == False 1 == True 2 is neither equal to True nor to False None is neither equal to True nor to False

Пример с Run Keyword If

В данном примере используется RFBrowser на основе Playwright

*** Settings *** Documentation Example that opens single page Library Browser ... enable_playwright_debug=${True} ... auto_closing_level=TEST ... retry_assertions_for=0:00:03 *** Variables *** ${url} https://devhops.ru *** Keywords *** Start Chromium Browser New Browser browser=chromium headless=False slowMo=1 New Context viewport={'width': 1920, 'height': 1080} ignoreHTTPSErrors=True *** Test Cases *** Starting a browser with a page Start Chromium Browser New Page https://devhops.ru ${sample_title} = Set Variable devhops.ru ${actual_title} = Get Title # With Run Keyword If Run Keyword If "${actual_title}" == "${sample_title}" Log To Console "1: Actual title is equal to sample title" # With IF IF "${actual_title}" == "${sample_title}" Log To Console "2: Actual title is equal to sample title" END IF "${actual_title}" != None Log To Console "3: Title exists" END IF "${actual_title}" != "heihei.ru" Log To Console "4: visited url is not heihei.ru" END Close Browser

python -m robot if.robot

======================================================================== If :: Example that opens single page ======================================================================== Starting a browser with a page ...devhops.ru .."1: Actual title is equal to sample title" ."2: Actual title is equal to sample title" ."3: Title exists" ."4: visited url is not heihei.ru" Starting a browser with a page | PASS | ------------------------------------------------------------------------ If :: Example that opens single page | PASS | 1 test, 1 passed, 0 failed ======================================================================== Output: /home/andrei/python/robot/rfbrowser/output.xml Log: /home/andrei/python/robot/rfbrowser/log.html Report: /home/andrei/python/robot/rfbrowser/report.html
