open_session(application = nil) — ActionController::Integration::Runner

open_session(application = nil)

Open a new session instance. If a block is given, the new session is yielded to the block before being returned.

session = open_session do |sess|
  sess.extend(CustomAssertions)
end

By default, a single session is automatically created for you, but you can use this method to open multiple sessions that ought to be tested simultaneously.

Parameters

application opt = nil
