minitest-bang

Provides the let! method to minitest spec, similar to the RSpec method of the same name.

gem install minitest-bang

or add the following line to Gemfile:

gem 'minitest-bang', require: false

and run bundle install from your shell.

Then in your test helper, after requiring minitest/autorun:

require 'minitest/bang'

Currently, minitest-bang supports minitest 4.7.5 through 5.4.0

You use it just like you would let, except the ones you define with let! are automatically invoked right before your before block gets executed:

  describe User do
    let!(:user1) { create :user }

    before do
      User.count.must_equal 1
    end

    it "has one user without referencing user1" do
      User.count.must_equal 1
    end
  end
