如何从Robot Framework中Run Keyword If下调用的关键字获取返回值? [英] How to get Returned value from a Keyword called under Run Keyword If in Robot Framework?

问题描述

我在我的机器人测试套件中为测试用例的拆卸写了一个关键字.下面提到:

I have written a keyword for Testcase teardown in my Robot Testsuite. Which is mentioned below:

*** Keyword ***
Result Evaluation
@{TRACEFILE} =  evalVirdict  ${value[2]}
:FOR  ${ELEMENT}  IN  @{TRACEFILE}
\    Log  ${ELEMENT}
\    Run Keyword if  '${TEST STATUS}'=='FAIL'  readerrlines  ${ELEMENT}

在上面的关键字 evalVirdict 是一个用 python 编写的函数，${value[2]} 来自我的测试用例和 Run Keyword if '${TEST STATUS}' == 'FAIL' readerrlines ${ELEMENT} 部分.我正在调用另一个函数 readerrlines ，它返回一些值.readerrlines 函数定义如下:

In the above Keyword evalVirdict is a function written in python and ${value[2]} is coming from my Testcases and in Run Keyword if '${TEST STATUS}' == 'FAIL' readerrlines ${ELEMENT} part. I am calling another function readerrlines which returns some value. The readerrlines function definition is below:

def readerrlines(tracefile):
    errVal = []
    for line in list(open(tracefile)):
        line = line.strip()
        mat = re.match(r'.*\s.*\s+:\s\*+(.*\s)\s{1}', line)
        if mat:
            err = mat.group(1).strip()
            errVal.append(err)
    return errVal

这里我想知道如何从 Run Keyword if '${TEST STATUS}' == 'FAIL' readerrlines ${ELEMENT} 中的 readerrlines 函数获取这个返回值?

Here i want to know how to get this returned value from readerrlines functions in Run Keyword if '${TEST STATUS}' == 'FAIL' readerrlines ${ELEMENT} ?

我已经尝试过 Run Keyword if '${TEST STATUS}' == 'FAIL' @{errval} = readerrlines ${ELEMENT} 但得到一个错误为非现有变量 @{errval还有 Run Keyword if '${TEST STATUS}' == 'FAIL' Set Variable @{errval} = readerrlines ${ELEMENT} 没有错误也没有输出.

I have tried Run Keyword if '${TEST STATUS}' == 'FAIL' @{errval} = readerrlines ${ELEMENT} but got an error as Non-Existing variable @{errval} and also Run Keyword if '${TEST STATUS}' == 'FAIL' Set Variable @{errval} = readerrlines ${ELEMENT} with no error and no output as well.

推荐答案

Run Keyword If 将返回它正在运行的关键字的结果.因此，你会这样做:

Run Keyword If will return the result of the keyword it is running. Thus, you would do:

${result}=    Run Keyword If    '${TEST STATUS}'=='FAIL'  readerrlines  ${ELEMENT}
