#mock_ldap_person(ldap_uid = 1) ⇒ Object

Adds mock user login functionality for testing apps using ucb_rails_security

The main advantage to using these helpers is that, when running your tests, actual ldap connections are never made, instead a mock ldap object is used. This dramatically increases the performance of your tests.

The helpers also avoid adding the logged in user to the users table, again this increases the speed of the tests.

Usage:

# log user into the application before controller test(s) are run.
before(:each) do
  () do
    User.create!(
      :ldap_uid => "666", 
      :first_name => "first_name", 
      :last_name => "last_name"
    )
  end
end

# log user into the application with specified roles before controller 
# test(s) are run.
before(:each) do
  (["security", "admin"]) do
    User.create!(
      :ldap_uid => "666", 
      :first_name => "first_name", 
      :last_name => "last_name"
    )
  end
end

One caveat, when using login_user_with_roles, the roles that are granted to the user are not saved to the database. For that user, we stub user.roles to return those roles. This means that you cannot add additional roles to this user during a test as roles() has been stubbed. The user you use to login should only be used to allow access to a given controller/action during your test.
