Module: RSpecMagic::Stable::UseLetset

Defined in:

lib/rspec_magic/stable/use_letset.rb

Overview

Define a method to create let variables, which comprise a Hash collection.

describe do
# Method is `let_a`. Collection is `attrs`.
use_letset :let_a, :attrs

# Declare `attrs` elements.
let_a(:age)
let_a(:name)

subject { attrs }

# None of the elements is set yet.
it { is_expected.to eq({}) }

# Set `name` and see it in the collection.
context_when name: "Joe" do
  it { is_expected.to eq(name: "Joe") }

  # Add `age` and see both in the collection.
  context_when age: 25 do
    it { is_expected.to eq(name: "Joe", age: 25) }
  end
end
end

When used with a block, let_a behaves like a regular let:

describe do
use_letset :let_a, :attrs

let_a(:age) { 25 }
let_a(:name) { "Joe" }

it { expect(attrs).to eq(name: "Joe", age: 25) }
end
