new to ruby and trying to minitest

i recreated a test directory, and placed all the necessary files in the

replaced gem 'minitest' with
              gem 'minitest-rails', '~> 0.1.0.alpha'
I replaced coz I was getting in error in the terminal which reads
              Could not find generator mini_test:install
therefore, again, I replaced and bundled. it then proceeded to create


i run the first test which is

require "minitest/autorun"
require "minitest/rails"

class ExercisesTest < ActionController::TestCase

  test "should get show" do
    get :show
    assert_response :success


and the output from the terminal reads

I need some hand holding setting up the directory now. what to test, and
how to write tests. I'm not looking just to get tests to pass ( I am)
but I'm wanting to know what the fuck I'm doing, really. None of this
half assed shit, ya know?

be well.

If you don’t know what you are doing, then learn the basics. Here is a free coupon for TDD in Ruby course for beginners:

I suggest working right through a good tutorial such as (which is free to use online). That will show you
the basics of rails including tests.


I've been working on that tutorial but still confused. thanks for
reaching out.

Where on the tutorial are you confused?


control flow. learning how to think. like, obviously I know exactly what
this test is doing

test "should get show" do
   get :show
   assert_response :success

however, when doing other testing on another application to help hone my
craft, I have no idea what the heels I'm doing.

thanks for reaching out. take care.

Finish the tutorial first, doing all the exercises, see if that helps.


ok, I will.

thanks again for reaching out. it's appreciated.
