Rails overwrite test_helper's configuration when running test

[Gastón Ba]

Hi

I want to overwrite some configurations only when running test with guard. 

Example, lets say I run test manually, on server host_a, now suppose I want capybara to run on a different server when running test with guard, this is my current test_helper:

Capybara.configure do |config| 

    Capybara.server_host='host_a'

    Capybara.server_port = '4000'

end

How can I configure guard to overwrite this configurations? I still want host_a as my default on my manual tests.

Hi,

You can probably set an environment variable in your `Guardfile` and use it in your `test_helper.rb`, e.g.: `Capybara.server_host = ENV['guard'] == 'true' ? 'host_b' : 'host_a'`

Hello,

I defined a callback,  callback(:start_begin) { ENV['guard'] = "host_a"} on my guardfile.

Is there a better way? I couldn't define an environmental variable only during guard execution
