You assignment is to fork this repository, clone your fork locally and complete a test first implementation of the following problem using RSpec as the testing library. Your GitHub repository will be the focus of our grading.
Your job is to create a class that has a single method called prime_number?, which takes one argument.
Instances of the class does not need to be initialized with anything special.
When you call prime_number? and pass it a prime number (like 3, 5 or 7), it returns true.
When you call prime_number? and pass it a non-prime number (like 4, 6 or 10), it returns false.
Your prime_number? method can use the Prime.prime? method from the Ruby standard library.
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself.
3,5,7,11,13,17,19 are all examples of prime numbers.
Each of the items below will be rated on a scale of 0, 1 or 2 (0 being did not do, 2 being did perfectly):
- A properly specified version of RSpec in your Gemfile
- Appropriately sized commits
- Descriptive commit messages
- Tests pass with each commit
- Code works
- Completed in time
- Ruby Style (proper capitalization / snake_case)
- A perfect prime number algorithm
It's sufficient to have one spec for a non-prime number and one spec for a prime number.
- Your self assessment of your performance submitted to yourself via the feedback tool in students.gschool.it
- Feedback from the instructors in the form of GitHub comments and via the feedback tool.
