Added selenium-webdrive to gemfile for javascript testing. Failed to get xhr or page.execute_script working for relationship controller tests. Used common matchers instead, not sure if they test the same functionality. Comments in code.
Completed 11.3.1 and 11.3.2
Finished 11.3.3, read up and played with the SQL tutorials on w3schools.
Finished 11.3.4, to get tests green I had to add :user_id to the attr accessible for the micropost model. Im uncertain the effect this has on the security and the general model. More research is needed.
