从机器人框架上的关键字传递参数

Question

I am new on python and robot framework. Previously, I use ruby as testing, and I oftenly use this

feature file:

Scenario : User can open browser
 User opens browser using "Chrome"


rb file:

And (/^User opens browser using "(.*)" $/) do |browser|{
   //open browser step
}

but when i try similar step on python like this

*Keyword*
User opens browser using ${browser}
  IF ${browser} == Chrome
  open browser  chrome
  ELSE
  open browser  firefox
  END

*Test Cases*
User should be able to open page with browser
   User opens browser using chrome

I got response No keyword with name 'User opens browser using chrome' found.

Can you help me guys? Or maybe there will be no clue to create similar steps on python robot framework? Thank you in advance

Answer 1

you need to send the ${browser} as a argument to the keyword like:

*** Test Cases ***
Open User Browser   ${browser}

***Keywords***
Open User Browser
[Arguments]   ${inputVar}   # this variable can be called anything
   IF   '''${inputVar}''' == '''Chrome'''
      open browser   chrome
   ELSE
      open browser   firefox
   END

It looks like some spacing is incorrect but it's difficult to know whether that's from copying into here. However it is possible to use embedded arguments within keywords and I can give you an example.

A couple of other things to note

1. The IF statement is a bit redundant as you can pretty much pass the variable Firefox or Chrome directly to the Open Browser paramter and make it a bit cleaner.

2. You can be strict on the embedded variables if you wish to by specifying them as different options as per example below

3. Open Browser usually takes url first - if you're not specifiying url then you may need to use named arg afaik

    *** Settings *** Library SeleniumLibrary Test Teardown Close Browser *** Test Cases *** User should be able to open page with browser User opens the chrome browser User tries to open an alternative browser User opens the firefox browser User tries to open browser not supported by keyword User opens the ie browser # Fails *** Keywords *** user opens the ${browser:(chrome|Chrome|firefox|Firefox)} browser Open Browser browser=${browser}

Both "Chrome" and "chrome" will work with Open Browser without switching capitilization though if you wanted to you could convert to lowercase before sending to open browser (Uses String library)

*** Keywords ***
user opens the ${browser:(chrome|Chrome|firefox|Firefox)} browser
    ${browser_lowercase}  Convert To Lowercase  ${browser}
    Open Browser  browser=${browser_lowercase}
