Module: RSpec::Core::DSL

Defined in:
lib/rspec/core/dsl.rb

Overview

DSL defines methods to group examples, most notably describe, and exposes them as class methods of RSpec. They can also be exposed globally (on main and instances of Module) through the Configuration option expose_dsl_globally.

By default the methods describe, context and example_group are exposed. These methods define a named context for one or more examples. The given block is evaluated in the context of a generated subclass of ExampleGroup.

Examples:

RSpec.describe "something" do
  context "when something is a certain way" do
    it "does something" do
      # example code goes here
    end
  end
end
