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

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

============================================================================== IF ELSE With Bool This is True .This is False .This is neither True nor False .This is False .This is True .This is neither True nor False .This is neither True nor False IF ELSE With Bool | PASS | ------------------------------------------------------------------------------ Demo | PASS | 1 test, 1 passed, 0 failed ==============================================================================

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://eth1.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://eth1.ru ${sample_title} = Set Variable eth1.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
