Run the tests from your terminal by using the rspec command, which will return “No examples found.” That really shouldn’t surprise you, because we haven’t written any tests yet. $ mkdir ruby_testing & cd ruby_testingĪs expected, the output will read: create. Create a new directory called “ruby_testing”, change into it, and initiate RSpec. How ‘bout a test to see the syntax? Let’s create a brand new “project” to get going. That wasn’t so hard, was it? Basic syntax Within two steps, you’re up and running with RSpec. rspec and spec/spec_helper.rb, such that your project might look like: project Take a minute also to hit rspec -help and look through the various options available.įinally, cd into a project directory that you wish to configure for use with RSpec and type rspec -init to initialize RSpec within the project. Once that’s done, you can verify your version of RSpec with rspec -version, which will output the current version of each of the packaged gems. Installing RSpecīoot up your terminal and punch in gem install rspec to install RSpec. ![]() Strap your helmet and buckle up we’re going to jump right in. RSpec’s wider adoption, especially in the Rails community, is certainly reason enough to warrant familiarity with it, but implementing tests should be the end-all and be-all, rather than choosing a particular framework.īut enough proselytizing. At the end of the day, it doesn’t matter which framework you choose as long as you cultivate your testing skills. Or perhaps you’re hungry and in the mood for something more substantial, in which case a side of Bacon might be what you need. If you tend to be pessimistic (Sorry, we meant realistic), then the Wrong testing framework might be your cup of tea. In fact, at one point, Ruby came bundled with Test::Unit and later Minitest as part of its standard library, the latter of which lives on in Rails. The rspec gem comes packaged with all you need to get started, including five gems: rspec, rspec-core, rspec-expectations, rspec-mocks, and rspec-support.Īt this point, you may be wondering, Why RSpec? Surely, there are other frameworks out there, and you’d be right. In this case, the task is testing Ruby code. Introduction to RSpec What is RSpec, and why RSpec?Īt the most basic level, RSpec is a Domain Specific Language written in Ruby, or, for the rest of us, a language specialized for a particular task. Look through these now and use them to guide your learning. It’s one of the most popular testing frameworks, having been downloaded more than 480 million times, at the time of this writing, and having been ported for use in Rails testing. In this lesson, we’ll introduce you to your new best friend, the RSpec testing framework. In the previous lesson, we established the utility of test-driven development (TDD) in maintaining your code and sanity.
