Congratulations! You're submitting your assignment!

Comprehension Questions

Question	Answer
Describe a design decision you had to make when working on this project. What options were you considering? What helped you make your final decision?	Deciding to make a room class or just an array of room ids. Talking it over with Chris during our on-on-one and in class when I recognized that the room class is just holding very little info.
Describe a concept that you gained more clarity on as you worked on this assignment.	I improved on design, I used more flow charts/ mapping to come up with a basic design, then wrote the tests and continuously ran the tests as I wrote the code itself.
Describe a nominal test that you wrote for this assignment.	testing if a reservation is able to be made when dates are given and there is available rooms
Describe an edge case test that you wrote for this assignment.	Testing if a reservation is able to be made when dates are given but there are no more available rooms. Trying to book more than 20 rooms in a single date range.
How do you feel you did in writing pseudocode first, then writing the tests and then the code?	I actually liked it, the pseudo code part on whiteboards was really helpful in determining edge cases and what variables/parameters I would use for specific methods.

What We're Looking For

Feature	Feedback
Design
Demonstrated classes having a single responsibility	For the most part, your `Admin` class is doing a bit much, but overall pretty good.
Demonstrated loose coupling	Very good work here, `Admin` depends on `Reservation` and `Block`, and `Block` depends on `Reservation`
Methods demonstrate a good use of encapsulation, inputs and outputs	Pretty good, see my comments.
Wave 1 requirements	Check
Wave 2 requirements	Check, but you have a bug in your logic, see my notes.
Wave 3 requirements	Check
Summary	Nice work, you showed a lot of growth here in design. Overall nicely done. You have some bugs in your code, but the design is pretty good overall. Checkout our reference implementation

lib/admin.rb

+      raise ArgumentError.new("#{room_id} is booked for these dates")
+    end
+
+    if available_rooms.count == 0


Ummm.. if there were no rooms then available_rooms would not include room_id.

CheezItMan · 2018-03-19T01:25:37Z

lib/admin.rb

+    @reservations.each do |reservation|
+      valid_check_in = check_in.between?(reservation.start_date, (reservation.end_date - 1))
+
+      valid_check_out = check_out.between?((reservation.start_date + 1), reservation.end_date)


What about if the reservation occurs entirely between check_in and check_out?

CheezItMan · 2018-03-19T01:27:50Z

lib/admin.rb

+    @reservations << Reservation.new(check_in, check_out, room_id)
+  end
+
+  def available_rooms(check_in, check_out)


To have wave 3 complete you may also need to check the blocks, or make sure add_reservation considers blocks.

I would suggest a method in reservation which either takes a Reservation or a date range and returns true if it overlaps with this reservation and false if it does not. It might make the logic easier in Admin.

specs/spec_admin.rb

+    @bookings[0].room_id.must_equal 1

This is really a test of the Reservation class.

specs/spec_block.rb

I'm unsure why you need to duplicate the array.
