Congratulations! You're submitting your assignment!

Comprehension Questions

Question	Answer
What was a design challenge that you encountered on this project?	I feel that up until now, the focus has been on code readability, even if it requires sacrificing memory efficiency or time efficiency. With this project the focus may have flipped?
What was a design decision you made that changed over time over the project?	I included a Date class in my design and it became the core of my code. However it appears to be not entirely necessary. I could have relied more heavily on iterating through my list of reservations to get the information that I needed. By the time, I realized this it was too late to change the code without starting over from scratch because of how central the Date class was to my code. However I still like the design. I think it is intuitive and readable.
What was a concept you gained clarity on, or a learning that you'd like to share?	I initially called Dates HotelDates. But modules are namespaces and I wanted to use the Hotel module appropriately. It was still causing conflicts with Ruby's built-in Date class. Chris recommended using ::Date, which does not specify a module and Ruby was able to differentiate between the two classes.
What is an example of a nominal test that you wrote for this assignment? What makes it a nominal case?	Reservations do not impact list of available rooms outside of date range. The dates are no where near overlap in this case.
What is an example of an edge case test that you wrote for this assignment? What makes it an edge case?	Reservations can be made if the check-in date is overlaps with the check-out date of another reservation for the same room. This is an edge case because there is an overlap in dates though rooms are available for check-in on the same day as another check-out.
How do you feel you did in writing pseudocode first, then writing the tests and then the code?	I pseudocoded my tests first and then wrote my code. I did it but I definitely did not enjoy it. Writing tests after writing the code feels more intuitive to me. It would also help me better create edge cases to test.

Overall Feedback

Great work overall! You've built your first project with minimal starting code. This represents an incredible milestone in your journey, and you should be proud of yourself! In particular nice work implementing Wave 3. Your use of inheritance for HotelBlock and the change_status method are quite clever.

+class FullOccupancyError < StandardError


This is a great example of defining your own appropriately named exception type.

Ruby will be looking for names locally first, prioritizing local names, since they're all in the same module, there's no need to namespace Hotel::Reservation. Reservation should just work! Same with the rest of the namespacing in the code.

clever use of select!

Great use of inheritance.

Nice use of a class method.

A comment to tell us what @dates is meant to hold would be useful, as it's not immediately obvious.

Consider assigning dates to variables in your tests to make it clear what you are testing.

Suggested change

expect(@first_res.start_date).must_equal ::Date.parse('2019-06-05')

start_date = Date.parse('2019-06-05')

end_date = start_date + 3
