I know, everyone uses Travis. I have nothing against it. But in case you want to test and/or use Shippable, this might be just the guide for you. I will also show how to setup that nice tabs with the test and coverage reports.
I’m writing this post because I found no blog post or anything compiling all the needed steps, just some parts here and there. I want to make it easy for new users to start testing their stuff using an Continuous Integration system.
So, this is my attempt to compile all that in a how-to like blog post.
The good stuff
First thing we need is the
.shippable.yml file. Mine looks like this:
language: ruby rvm: - 2.1.2 script: - bundle exec rake test env: global: - CI_REPORTS=shippable/testresults COVERAGE_REPORTS=shippable/codecoverage
env is required for that nice tabs I said before to work.
Don’t forget to add the required stuff to
source "https://rubygems.org" gem "rake" # make sure you have rake here! # ... group :development, :test do gem "minitest" gem "simplecov" gem "simplecov-csv" gem "minitest-reporters" end
I also created a
Rakefile (so I can call it in the
require 'rake/testtask' Rake::TestTask.new do |t| t.pattern = "spec/*_spec.rb" end
The last thing we need is the
require "simplecov" require "simplecov-csv" SimpleCov.formatters = [ SimpleCov::Formatter::HTMLFormatter, SimpleCov::Formatter::CSVFormatter, ] SimpleCov.coverage_dir(ENV["COVERAGE_REPORTS"]) SimpleCov.start # you might want to pass 'rails' and/or a block here require "minitest/autorun" require "minitest/reporters" MiniTest::Reporters.use!([ MiniTest::Reporters::DefaultReporter.new, MiniTest::Reporters::JUnitReporter.new( ENV["CI_REPORTS"] || "coverage/ci" ) ]) require_relative "../lib/mylibrary" # change to your library here
Most of this stuff is for Shippable to correctly parse test and coverage results. The order of the stuff here does matter. Don’t change it if you don’t know what you’re doing.
With that being said, now, our specs will just have to
spec_helper, and everything should work like magic when you run
bundle exec rake test.
I had some trouble with compatibility issues related to Ruby’s
To clarify: there is the
minitest gem and the
minitest inside Ruby itself.
If you use RVM (Shippable does), you will find it under
Unfortunately for me, I use
rbenv, and, for some reason I don’t yet
rake test worked beautifully. With Shippable and RVM, I got this:
/home/shippable/.rvm/gems/ruby-2.1.2/gems/minitest-5.5.1/lib/minitest/assertions.rb:17: warning: already initialized constant MiniTest::Assertions::UNDEFINED /home/shippable/.rvm/rubies/ruby-2.1.2/lib/ruby/2.1.0/minitest/unit.rb:80: warning: previous definition of UNDEFINED was here Emptying /home/shippable/workspace/src/bitbucket.com/repo/repo/shippable/testresults
To fix that, I just had to change the
rake test to
bundle exec rake test
(as already demonstrated in the
.shippable.yml file in the beginning of this
post). Simple fix for a hard-to-understand problem.
