The purpose of this repository is to provide 'hands-on' RSpec lessons. These lessons were designed to equip students of the The Odin Project to write tests for their Tic-Tac-Toe and to TDD their Connect Four.
These lessons cover many topics, but it does not cover everything that RSpec is capable of testing. You should expect to learn foundational knowledge on the following topics:
- Let Variables
- Implicit and Explicit Subject
- A variety of built-in-matchers
- Setting values for instance variables to create test conditions
- The 'Arrange, Act & Assert' testing pattern
- Stubs, Mocks, and Doubles
- Test Driven Development
Run rbenv versions to confirm that you have ruby version 3.2.2 installed. If you do not have this version installed, please refer back to these instructions to install it.
Run bundle install from the root directory.
These lessons are numbered 01 - 16, in the spec folder. Start with the file: spec/01_string_spec.rb. The first 9 lessons are self-contained in the spec file. Starting with lesson 10, there will be 1-3 corresponding files in the lib folder.
If you get stuck on a lesson, there is a corresponding answer file located in the spec_answer folder.
Since this repository is full of tests, it is recommended to only run rspec on one individual file at at time. For example, to run the first test file from the root of this directory:
rspec spec/01_string_spec.rbTip: If you have tab completion set-up, you can hit 'tab' after the first few characters of the file name.
