How can we pass different browser at once in robotframework

I see 2 ways to do it.

1) loop over your browser and call a keyword that do your test:

*** Variables ***@{BROWSERS}          firefox  chrome  IE*** test cases ***test with several browser    :FOR  ${browser}  IN   @{BROWSERS}    \  log to console  call keyword that does your test with ${browser}

Here is what you get with this test:

[Mac]$ pybot .Browser.Ts==============================================================================test with several browser                                             call keyword that does your test with firefoxcall keyword that does your test with chromecall keyword that does your test with IEtest with several browser                                             | PASS |------------------------------------------------------------------------------Browser.Ts                                                            | PASS |1 critical test, 1 passed, 0 failed1 test total, 1 passed, 0 failed==============================================================================

2) another way (which I prefer) is to keep your ${BROWSER} variable with a single value and call your test case several time with a new value for the variable that you give on the command line:

[Mac]$ pybot --variable BROWSER:firefox ts.txt[Mac]$ pybot --variable BROWSER:chrome ts.txt[Mac]$ pybot --variable BROWSER:ie ts.txt

Ok I think I've solved this problem by writing a simple script.

I Just wrote a program which will read the file settings.txt and find the line @{BROWSER} firefox chrome IEand then extract browsers name and store into a list . so this script will return a List something like this['firefox', 'chrome', 'IE']

now instead of using single pybot command I'll use it in a Loop

for browser in browsers:        call(['pybot','--variable'] +['BROWSER:%s'%browser] + test_args) 

settings.txt file will contain two variable

${BROWSER}          firefox      #So default browser is firefox. you can leave it blank@{BROWSERS}         firefox  chrome  IE
