Using RSpec without Rails

Using RSpec without Rails

gem install rspec

# .rspec
# spec/spec_helper.rb

# spec/spec_helper.rb
# This file was generated by the `rspec --init` command. Conventionally, all
# specs live under a `spec` directory, which RSpec adds to the `$LOAD_PATH`.
# The generated `.rspec` file contains `--require spec_helper` which will cause this
# file to always be loaded, without a need to explicitly require it in any files.
#
# Given that it is always loaded, you are encouraged to keep this file as
# light-weight as possible. Requiring heavyweight dependencies from this file
# will add to the boot time of your test suite on EVERY test run, even for an
# individual file that may not need all of that loaded. Instead, consider making
# a separate helper file that requires the additional dependencies and performs
# the additional setup, and require it from the spec files that actually need it.
#
# The `.rspec` file also contains a few flags that are not defaults but that
# users commonly want.

# and `failure_message` of custom matchers include text for helper methods
# defined using `chain`, e.g.:
# be_bigger_than(2).and_smaller_than(4).description
# # => "be bigger than 2 and smaller than 4"

I am getting NoMethodError: undefined method `post' for #<RSpec::ExampleGroups::Create:0x00007ffe72a4de90>

describe '#create' do
  it "should create a user" do
    post "/create"
  end

You don't need rspec --init just install the gems and put this in your file.rb

require 'rspec'

define_method(:fib) { |n| n < 3 ? 1 : fib(n - 2) + fib(n - 1) }
RSpec.describe do it { expect(fib(10)).to eq(55) } end

and then run

rspec file.rb

@Salomanuel make sure you don't alias rspec to bundle exec rspec somewhere.
