Instance Method Details

#to(target = nil) ⇒ AddInstanceMethodTo

Builds final matcher

The matcher checks if a method was added to a class or instance

Examples:

Using inside RSpec and checking an instance method being added

RSpec.configure do |config|
  config.include Sinclair::Matchers
end

class MyModel
end

RSpec.describe "MyBuilder" do
  let(:clazz)   { Class.new(MyModel) }
  let(:builder) { Sinclair.new(clazz) }

  before do
    builder.add_method(:new_method, "2")
  end

  it do
    expect { builder.build }.to add_method(:new_method).to(clazz)
  end
end

# Outputs
# 'should add method 'new_method' to #<Class:0x000056441bf46608> instances'

Using inside RSpec and checking instance

RSpec.configure do |config|
  config.include Sinclair::Matchers
end

class MyModel
end

RSpec.describe "MyBuilder" do
  let(:clazz)    { Class.new(MyModel) }
  let(:builder)  { Sinclair.new(clazz) }
  let(:instance) { clazz.new }

  before do
    builder.add_method(:the_method, "true")
  end

  it do
    expect { builder.build }.to add_method(:the_method).to(instance)
  end
end

# Outputs
# 'should add method 'the_method' to #<Class:0x000056441bf46608> instances'

Parameters:

  • target (Class, Object) (defaults to: nil) —

    where the method will be added
