RF--evaluate關鍵字

evaluate后面的參數為condition，和should be true一樣，詳情請看rf--基礎中的should be true

evaluate作用為執行后面的python表達式賦值給前者

${var}    set variable    ${890}

完全可以寫成

${var}    evaluate    890

 

復雜的表達式：

*** Test Cases ***
case1
    ${alist}   evaluate    ['hello']*3
    log to console   ${alist}
結果：
['hello', 'hello', 'hello']

*** Test Cases ***
case2
    ${alist}   evaluate    [i for i in range(10)]
    log to console   ${alist}
結果：
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

*** Test Cases ***
case3
    ${alist}   evaluate    [i for i in range(10)]
    ${alist}    evaluate  $alist[:5]    #evaluate作用為執行后面的python表達式，后面的參數類似should be true
    log to console   ${alist}
結果：
[0, 1, 2, 3, 4]

 

evaluate后面不能帶 =

*** Test Cases ***
case4
    ${alist}   evaluate    [i for i in range(10)]
    ${alist}    evaluate  $alist[0]=9    #evaluate后的參數類似should be true
    log to console   ${alist}
結果報錯：
Evaluating expression 'RF_VAR_alist [0 ]=9' failed: SyntaxError: invalid syntax (<string>, line 1)
