Scaffold generated code not passing rspec - ruby-on-rails

Question

I am new to Rspec and I am following a tutorial, I ran the following commands on a new rails project:
bundle exec rails generate scaffold Person first_name:string last_name:string
bundle exec rake db:migrate db:test:prepare
bundle exec rspec
And I get 15 failures, some of them shown below:
1) PeopleController POST create with valid params redirects to the created person
Failure/Error: response.should redirect_to(Person.last)
NoMethodError:
undefined method `assertions' for #<RSpec::Rails::TestUnitAssertionAdapter::AssertionDelegator:0x007fe7b2417980>
# ./spec/controllers/people_controller_spec.rb:80:in `block (4 levels) in <top (required)>'
2) PeopleController POST create with invalid params assigns a newly created but unsaved person as #person
Failure/Error: post :create, {:person => { "first_name" => "invalid value" }}, valid_session
ArgumentError:
wrong number of arguments (1 for 2+)

# ./app/controllers/people_controller.rb:29:in `create'
# ./spec/controllers/people_controller_spec.rb:88:in `block (4 levels) in <top (required)>'
3) PeopleController POST create with invalid params re-renders the 'new' template

5) PeopleController PUT update with valid params redirects to the person
Failure/Error: response.should redirect_to(person)

Here is the people controller its referring to
class PeopleController < ApplicationController
before_action :set_person, only: [:show, :edit, :update, :destroy]
# GET /people
# GET /people.json
def index
#people = Person.all
end
# GET /people/1
# GET /people/1.json
def show
end
# GET /people/new
def new
#person = Person.new
end
# GET /people/1/edit
def edit
end
# POST /people
# POST /people.json
def create
#person = Person.new(person_params)
respond_to do |format|
if #person.save
format.html { redirect_to #person, notice: 'Person was successfully created.' }
format.json { render :show, status: :created, location: #person }
else
format.html { render :new }
format.json { render json: #person.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /people/1
# PATCH/PUT /people/1.json
def update
respond_to do |format|
if #person.update(person_params)
format.html { redirect_to #person, notice: 'Person was successfully updated.' }
format.json { render :show, status: :ok, location: #person }
else
format.html { render :edit }
format.json { render json: #person.errors, status: :unprocessable_entity }
end
end
end
# DELETE /people/1
# DELETE /people/1.json
def destroy
#person.destroy
respond_to do |format|
format.html { redirect_to people_url, notice: 'Person was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_person
#person = Person.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def person_params
params.require(:person).permit(:first_name, :last_name)
end
end
Why is a scaffold generated code failing these rspec tests?

Are you also using minitest? Try changing the version in your gemfile to e.g.:
gem 'minitest', '~> 4.0'
