RSpec Core Fundamentals

RSpec is a behavior-driven development (BDD) testing framework for Ruby. This skill covers the core DSL for structuring and writing specs.

Example Group Structure

describe and context

Use describe for the thing being tested (class, method, behavior). Use context for different scenarios or states:

RSpec.describe User do
  describe "#full_name" do
    context "when user has both names" do
      it "returns first and last name" do
        user = User.new(first_name: "John", last_name: "Doe")
        expect(user.full_name).to eq("John Doe")
      end
    end
