Course overview
Build your first engineering strategy
Becoming a technical leader or Chief Technical Officer (especially a de facto one) is not easy. Many challenges arise one after the other.
This course aims to prevent you from panicking or losing sight of what matters by giving you a base foundation you can build upon.
This is for
01
the junior Ruby developers looking to pick up a key skill
02
the experienced Ruby developers who wants to complete their toolbox
Key outcomes
Learn how to write clear, modular tests
Ruby syntax is powerful, and RSpec's Domain Specific Language inherits from it. You will learn how to rely on it to write clear and modular tests.
Raise the quality of your tests
RSpec and Rails have a great ecosystem of libraries and tools to complement them. With Faker and FactoryBot, we will see how to streamline the creation of test data that is full of sense and not brittle.
Develop a good understanding of the different types of tests
There are plenty of layers to tests in Ruby applications: we will see which ones to focus on and how to avoid walking on our own steps when doing so.
A step towards Test-Driven Development
Once we have a good grasp of how to write tests, we will get to Test Driven Development.
We won't have time to get perfect at it, but we will see how this approach can turn our approach to writing code on its head and for good.

Course syllabus
01
Learning RSpec bases
We will cover all the bases of RSpec:
- how to install it in a project
- how to prepare the files structure
- how to write a first test
- how to run the test
Then we will start to get more details about how to write tests for real:
- basic assertions and expectations
- the built-in matchers
02
Diving dipper: more matchers
The second module covers further the syntax of RSpec with more advanced concepts.
- Advanced matchers (predicate, collections, exceptions, ...)
- Custom matchers
- Contexts & Hooks
03
Pushing further: shared examples, factories
Once we have learned how to write plenty of tests we will see how to write tests for our ActiveRecord models:
- beyond simple classes
- factories of data
- shared examples
04
Smoke and mirrors: mocking, stubbing
Some tests require plenty of isolation. To do so, we will see a few topics to help:
- mocking & stubbing
- additional factory tricks
- how to deal with API calls
05
Test Driven Development: writing tests to shape our code
This part is about how to stop seeing tests as an afterthought of writing code to implement a feature.
This part is about how to start seeing tests as part of the feature, part of the design of the code itself.
Course schedule
