These are: +- The tests are authoritative and take precedence over the code +- Any code or requires that were not used by the tests were not needed and could + be removed +- Since the assignment here is to “make the tests work and refactor the code” + rather than “make the code work”, I added stub! statements to the tests to + make up for any functionality missing from the main code even if the + additions might have been trivial +- I noticed that many of the missing methods are available in the context of a + Rails application. At first I tried to find a way to run the tests in the + context of a Rails application so that these methods would be available, but + started thinking that that was outside the scope of the assignment and + decided to use the stub! statements instead. The fact that all the tests + tested against strings like “just image” instead of real paths, URLs, or HTML + tags helped me to solidify my opinion that this was the best way to go + +Given the information I was provided with and the lack of context that comes +with that, I saw two main tasks for refactoring here: +1) get rid of unused or duplicated code +2) clean up the redundancy in the class structure + +Getting rid of unused or duplicated code was easy. With the class structure, +again due to lack of context, I had to make some judgment calls. It seems to me +that a user and a profile are essentially the same thing. I saw nothing to +indicate that a profile might have more than one user or that a user could be +used without a profile. Given that, I removed the User class and updated +helper.rb and helper_spec.rb to reflect those changes. Factory Girl and the +Profile class aren’t used by the tests so I removed all references to those with +no other changes needed. + +The two files that I made major changes to are helper.rb and helper_spec.rb. As +I made changes I put in comments to describe why each change was made. This made +the code hard to read while refactoring so I saved the commented versions as +helper_notated.rb and helper_spec_notated.rb and then removed most of the +comments in the original files. As I refactored I tried to keep the two copies +in sync and am submitting the notated versions in case you would like more +insight into the process which I used in this assignment. That said, there could +be slight variations between the notated and non-notated versions, but both +versions run correctly for all the tests. diff --git a/refactor-this/helper.rb b/refactor-this/helper.rb index 6ef273b..83ff928 100644 --- a/refactor-this/helper.rb +++ b/refactor-this/helper.rb @@ -1,67 +1,24 @@ class Helper - def self.foo - "foo" - end - - def image_size(profile, non_rep_size) - if profile.user.rep? - '190x114' - else - non_rep_size - end - end - - def display_small_photo(profile, html = {}, options = {}) - display_photo(profile, image_size(profile, "32x32"), html, options) - end - - def display_medium_photo(profile, html = {}, options = {}) - display_photo(profile, image_size(profile, "48x48"), html, options) - end - - def display_large_photo(profile, html = {}, options = {}, link = true) - display_photo(profile, image_size(profile, "64x64"), html, options, link) - end - - def display_huge_photo(profile, html = {}, options = {}, link = true) - display_photo(profile, image_size(profile, "200x200"), html, options, link) - end def display_photo(profile, size, html = {}, options = {}, link = true) - return image_tag("wrench.png") unless profile # this should not happen + # NOTE: if this "should not happen" why is it here and why is there a unit test for it???
