gburtini / test_induced_design_damage.rb
Created August 26, 2020 19:57 — forked from dhh/test_induced_design_damage.rb
This is an extraction from Jim Weirich's "Decoupling from Rails" talk, which explained how to apply the hexagonal design pattern to make every layer of your application easily unit testable (without touching the database etc). It only seeks to extract a single method, the EmployeesController#create method, to illustrate the design damage that's …
# Original Rails controller and action
class EmployeesController < ApplicationController
def create
@employee = Employee.new(employee_params)
if @employee.save
redirect_to @employee, notice: "Employee #{@employee.name} created"
else
render :new
end
