Run SystemSpec (RSpec) and Rubocop on CircleCI

Introduction

I ran SystemSpec (RSpec) and Rubocop using CircleCI.

I've compiled the source code that I actually used from basic learning, so I hope it will be helpful.

Basic learning

Teaching materials: Introduction Guide-CircleCI I've just started CircleCI, so I've summarized it in an easy-to-understand manner

I did the officially prepared Introduction Guide --CircleCI to know the basic usage. It is recommended that you can study while moving your hands and it will take about 30 minutes.

Next, I read I've just started CircleCI, so I've summarized it in an easy-to-understand manner. This article describes CircleCI in great detail. After a quick read at first, I reread this article if I had any questions.

CircleCI implementation

References

Based on the official CircleCI-Public / circleci-demo-ruby-rails I implemented it while referring to [circleCI] Run rubocop and rspec test in cooperation with github with Rails app.

Since the official sample uses the latest version, there were not many references such as Qiita.

This time I will use the latest version: 2.1.

Premise

--You must have a github account --You already have a rails project --Mysql is used for the database. --rspec and rubocop are installed and configured
