New to ruby and trying to minitest

Rails
1

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

rails 3.2.21
ruby 2.1.4

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
test/minitest_helper.rb

anyway.

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
end

end

and the output from the terminal reads

Errors running test:units! #<NoMethodError: undefined method `[]’ for
nil:NilClass>

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
railstutorial.org (which is free to use online). That will show you
the basics of rails including tests.

reaching out.

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
end

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.
