ruby - How to run RSpec scripts with custom arguments -

-

i have specific requirement run rspec scripts supplying configuration file during run time.

rspec doesn't allow supply custom arguments through command-line except pre-defined ones "--tag, --format, --output etc.."

is there workaround this?

after lot of digging in through various online resources , stackoverflow, found workaround this:

by using dotenv gem, can achieve this.

install dotenv 

$ gem install dotenv

create .env file in test script folder custom arguments "key=value" pairs, e.x:

config_file=test_config.yaml

read values environment variables in spec file

require 'dotenv' dotenv.load  describe "passing arguments"   before(:all)     @configfile = env['config_file']   end    "initiating device config"     puts "using device config file #{@configfile}"   end end

now read config file name environment variable in test scrips.
