機器人框架：創建一個帶有可選參數的關鍵字。 參數的默認值應該來自腳本

Question

我正在嘗試創建一個將 python 腳本方法作為默認參數的關鍵字，如下所示：

*** Settings ***
Library  SeleniumLibrary
Library  BuiltIn
Library  ./../python_scripts/folders.py

*** Keywords ***
Create subfolder inside mainfolder through right click
    [Arguments]  ${PARENT_FOLDER}=folders.get_last_folder
    press element  ${PARENT_FOLDER}
    right click and add folder
    basic folder creation process
    save folder
    assert created folder exists

問題是，當我運行此步驟時，它Element 'folders.get_last_folder' not visible after 5 seconds. 為了將${PARENT_FOLDER}的默認值作為方法 folders.get_last_folder folders.get_last_folder()的 output，正確的語法是什么？

Answer 1

您不能在 Arguments 部分運行函數，folders.get_last_folder 被認為是一個字符串。 您需要使用“Run Keyword If”來有條件地設置變量，如下所示：

*** Keywords ***
Create subfolder inside mainfolder through right click
    [Arguments]  ${PARENT_FOLDER}=folders.get_last_folder
    ${PARENT_FOLDER}=    Run Keyword If    "${PARENT_FOLDER}" == "folders.get_last_folder"    folders.get_last_folder
    ...                  ELSE              Set Variable    ${PARENT_FOLDER}
    press element  ${PARENT_FOLDER}
    right click and add folder
    basic folder creation process
    save folder
    assert created folder exists
