Your infrastructure as an application. - Automation, the killer app. A true app. - Version environments, speed up cycles. - Turn the focus back to the business. What is infrastructure as code?
not mean tested - Business value of your ‘app’ - Tests are outcome focused* - Investment in quality - CI/CD, continuous testing or monitoring - CD is the new economy; customer service Why should you test infrastructure?
- Continuous all the things - Everyone loves DSLs - Focus on ruby tools, but extensible - API driven; how long is the build broken? Types of testing; tonight’s talk
OO, Func, Dynamic) - Conceived 1994, released 1995, English in 1998/99, more popular than Python in Japan by 2000 - Bundler, Gemfile - rbenv, rvm, chruby - DSL friendly Ruby, toolchain overview
admin privileges' do before :each do @admin = Admin.get(1) end it 'should exist' do expect(@admin).not_to be_nil end it 'should have a name' do expect(@admin.name).not_to be_false end end #... end Unit testing with rspec
'installs foo' do expect(chef_run).to install_package('foo') end end Unit testing with chefspec - Completely compatible with most chef tools - Stub other node data and environment data - Mock objects, return results
