Imagine you want to write a cucumber test for a user-to-user chat. To do this, you need the test to work with several browser sessions, logged in as separate users, at the same time.
Luckily, Capybara makes this relatively easy:
Scenario:
Scenario: Alice and Bob can chat
Given Alice, Bob, and a chat session
When I am signed in as "Alice"
And I go to the chat
And I am signed in as "Bob" [session: bob]
And I go to the chat [session: bob]
And I send the message "Hello, this is Alice!"
Then I should see "Hello, this is Alice!" within the chat
And I should see "Hello, this is Alice!" within the chat [session: bob]
Capybara has a method Capybara.using_session allowing you to perform steps in different browser sessions, so all you need is the following:
When(/^(.*) \[session: (.*?)\]$/) do |step_text, session_name|
Capybara.using_session(session_name) do
step(step_text)
end
end
Effect on other step definitions
Be careful that this also affects other steps. For example, we often use something like this for authentication:
module AuthenticationSteps
def sign_in(user)
sign_out if @current_user # BROKEN!
login_as user
@current_user = user
end
# ...
end
World(AuthenticationSteps)
This will not work, since now there is no longer one logged in user, but potentially several.
Work around this with something like:
module AuthenticationSteps
def reset_signed_in_users
@current_users = {}
end
def sign_in(user)
sign_out if @current_users[Capybara.current_session]
login_as user
@current_users[Capybara.current_session] = user
end
# ...
end
World(AuthenticationSteps)
Before do
reset_signed_in_users
end
