Read and store definitions from an outer file

Ruby
1

Hi guys, I am a newcomer to Ruby, i got into it by having to make
testing scripts for my company. I have not had such problem that i
couldn’t solve by reading, but now I encountered one. I have made some
test suites using watir gem which include definitons like user name and
test page address. But if i move to an other environment i have to
modify these for each test suite. What i would like to achieve: I would
like to have a single file(testreq.txt for example) containing these
definitions and I would like to make my test suites to read and store
these values from my testreq.txt file. Thank you very much for your help
in advance!

Best wishes,
Alex

Hey,

I normally use a module filled with constants.

Module foo
PropertyOne=“some value”
End

Then just require the module from somewhere else.

If you have complex config needs, try serialising data structures to and
from Yaml.

Hi,

Using a Module as Jam suggested is probably the simplest way.

But of course there are also many data formats you can use. I actually
prefer JSON over YAML, because it’s simpler and more “robust”. Reading
and writing works pretty much like with YAML:

require ‘json’

config_file = ‘config.json’

write

new_config = {
name: ‘some name’,
address: ‘some address’
}
File.open(‘config.json’, ‘w’) {|f| f << new_config.to_json}

#read
current_config = JSON.parse File.read config_file
puts current_config

For a config file that I or (somebody else) might want to edit
directly, I find YAML more human readable than JSON

JSON:
{“name”:“some name”,“address”:“some address”}

YAML:
:name: some name
:address: some address

But, of course, that’s a matter of taste.

you could use YAML:

require ‘yaml’

config_file = ‘testreq.txt’

config = {:name => ‘User’, :address => ‘Address’}
File.open(config_file, ‘w’) {|f| f.write(config.to_yaml) }

or: File.open(config_file, ‘w’) {|f| YAML.dump(config, f) }

saved_config = YAML::load_file(config_file)
puts “Name: #{saved_config[:name]}” #=> Name: User
