【问题标题】:Switch statement in robot Framework机器人框架中的switch语句
【发布时间】:2020-09-04 10:08:27
【问题描述】:
我实际上在机器人框架中使用了很多 if 语句,这些语句很容易成为 switch 语句。
我在机器人框架中找不到任何 switch 语句的例子(它甚至存在吗?)。
这是我的代码的一部分:(在我的代码中,像这样的 if 语句有 50 多种可能性,它非常庞大,日志太大而无法找到信息片段(所有 if 都写在日志文件中,即使是那些错误的)。
感谢您的帮助
# 1st posibility
\ ${varA} Run Keyword And Continue On Failure Run Keyword If '${Type}' == 'Deal' keyword1 ${Name}
# 2d posibility
\ ${varB} Run Keyword And Continue On Failure Run Keyword If '${Type}' == 'Scenario' and '${varA}' != 'None' keyword2 ${Name}
# 3rd posibility
\ ${varC} Run Keyword And Continue On Failure Run Keyword If '${Type}' == 'Site' and '${varA}' != 'None' keyword3 ${Name}
# 4th posibility
\ Run Keyword And Continue On Failure Run Keyword If '${Type}' == 'SiteFile' and '${varA}' != 'None' keyword4 ${varA}

【解决方案1】:
这是我所做的。
我的日志是易读的
test.robot
*** Settings ***
Library myLib.py
*** Test Case ***
TC_run
Switch Keyword ${Type}
myLib.py
def Calculate_funct(var1):
BuiltIn().run_keyword('CalculateKeyword', '${el1}', '${el2}','${el3}')
def ValidateSite_funct(var1):
if Id != "" :
BuiltIn().run_keyword('ValidateKeyword', '${el1}', '${el2}')
else :
return "error"
def switch_keyword(keyword, **kwargs):
"""select the correct function to apply in function of the given keyword.\n

arguments: columns content.\n
"Calculate"\n
"Validate"\n

"""
switcher = {
"Calculate": Calculate_funct,
"Validate" : Validate_funct,
}
func = switcher.get(keyword, lambda: "invalid keywork")
returned_thing = func(**kwargs)
return returned_thing
【解决方案2】:
如果在所有情况下您都根据单个值(即${Type})决定执行哪个关键字,那么您可以尝试使用type=keyword 之类的映射创建字典并动态找出要执行的关键字。下面是一个简单的例子:
*** Settings ***
Library Collections
*** Variables ***
&{TYPE_MAPPING} deal=keyword1 scenario=keyword2 site=keyword3 sitefile=keyword4
*** Test Cases ***
Dynamic-Keyword-Name
Take Action Based On Type deal
Take Action Based On Type scenario
Take Action Based On Type site
Take Action Based On Type sitefile
Take Action Based On Type xyz
*** Keywords ***
Take Action Based On Type
[Arguments] ${type}
${kw_name} Map Type To Keyword Name ${type}
Run Keyword And Continue On Failure ${kw_name}
Map Type To Keyword Name
[Arguments] ${type}
${result} ${value} Run Keyword And Ignore Error Get From Dictionary ${TYPE_MAPPING} ${type.lower()}
Run Keyword If '${result}' == 'FAIL' Fail msg=Was not able to map type "${type}" to keyword name
Return From Keyword ${value}
keyword1
Log Deal
keyword2
Log Scenario
keyword3
Log Site
keyword4
Log SiteFile
