kyletcarlson / rspec_model_testing_template.rb
Last active Sep 12, 2019
Rails Rspec model testing skeleton & cheat sheet using rspec-rails, shoulda-matchers, shoulda-callbacks, and factory_girl_rails. Pretty much a brain dump of examples of what you can (should?) test in a model. Pick & choose what you like, and please let me know if there are any errors or new/changed features out there. Reddit comment thread: http…
View rspec_model_testing_template.rb
# This is a skeleton for testing models including examples of validations, callbacks,
# scopes, instance & class methods, associations, and more.
# Pick and choose what you want, as all models don't NEED to be tested at this depth.
# I'm always eager to hear new tips & suggestions as I'm still new to testing,
# so if you have any, please share!

Created Dec 11, 2013
Ruby script that uses open-uri to fetch the contents of a JSON endpoint, uses the JSON gem to parse the string into a Ruby array & prints some of the records. This is the foundation for all web API requests, so feel free to use it in the future.
View json_response_handling_ruby.rb
require 'open-uri'
require 'json'
require 'pp'
# Construct the URL we'll be calling
request_uri = 'http://localhost:3000/users.json'
request_query = ''
kyletcarlson / ruby-open-uri-request.rb
Created Dec 9, 2013
4-line Ruby script that uses open-uri to fetch the contents of a URL & displays it in the console. This is the foundation for all web requests, whether to scrape a page, request a JSON response, and more.
View ruby-open-uri-request.rb
require 'open-uri'
# Go fetch the contents of a URL & store them as a String
response = open('').read
# "Pretty prints" the result to look like a web page instead of one long string of HTML
# Print the contents of the website to the console

kyletcarlson / deploy.rb
Created Dec 19, 2013
A sample Capistrano deploy.rb file I use as a base for all my projects. It's a straightforward & doesn't add much custom functionality besides symlinking my database.yml into my project from a folder outside of my application (considered good security practice).
View deploy.rb
require 'bundler/capistrano'
# Include this if you want to be able to set up different deployment stages (i.e. beta, stage, etc.)

Created Dec 9, 2013
A Ruby web scraping script that visits a GitHub trending repos page, scrapes the data for the 25 repos, loads them into a CSV, and then reads from the CSV & creates a hash with each repo's data.

kyletcarlson / ruby_benchmark_examples.rb
Created Dec 14, 2013
Three examples showing three of the main methods of Ruby's Benchmark class that's used to profile your code. Benchmark.measure at the most basic, Benchmark.benchmark allows you to run trials of different code blocks, and Benchmark.bmbm that helps you establish a baseline for your tests.
View ruby_benchmark_examples.rb

# Set the number of iterations to run. The underscore here is used as a substitute for normal comma so Ruby interprets the number correctly.
iterations = 10
puts "\nCalculating pi #{iterations} times.\n\n"
You can’t perform that action at this time.
