67-272: University

This project was created as means of giving students an opportunity to practice course concepts with some in-class learning exercises. There is no pretense that this is a production-ready system or that it has 100 percent test coverage -- these are for learning purposes.

Some items and helper files have been added in advance to speed up time in-class to complete these exercises. For example, Prof. H's minitest_extensions module is present and included in test/test_helper.rb by default. Another example is that validates_timeliness gem is installed and the initializer for that gem has also been run for you. Note that time zone in config/application.rb was defaulted to Eastern (Pgh) time; feel free to change this as appropriate.

You may work and talk with others in class for help completing this exercise.

Instructions for Part 1

Having cloned this repo to your laptop (recommended) or gotten the zip file from GitHub, we need to set up the project as follows:

  1. Install gems with bundle install

  2. Create the database with rails db:migrate

  3. Open up app/models/department.rb and review the code

  4. Open up app/models/faculty.rb and review the code comments given

  5. Open up test/models/faculty_test.rb and complete the tests so the methods commented on will be covered properly and completely

    • this will require you to set up a context for faculty (skelton already in place). Looking at the factory file for faculty, you see that Prof. Q is the default faculty member; probably a good idea to create the first faculty object as @profq. Of course, also make sure that not every faculty you create is named 'Jeria Quesenberry' ;-)
    • before testing, load the testing data into a clean copy of your dev database with the command rails db:contexts. (Note that this is not built into Rails; it was written for you and also exists in your project starter code.) Once that's done and the contexts build without error, re-open rails console and run Department.all and Faculty.all and see that the testing context data is loaded in the dev environment.

  6. Run the tests and see that tests for department passes while tests for faculty fail.

  7. Complete the code in app/models/faculty.rb so that the tests pass with 100% test coverage

  8. What would Faculty.alphabetical.active.first.department return in rails console? Go to rails console and verify that you are correct (or if not, figure out why you were wrong)
