#Add test files to rails app chef driver

Therefore, I usually stick with a headless driver called Poltergeist. The problem, however, is that Selenium is somewhat slow and not headless, meaning that when the system tests are being executed, the browser literally opens and you see all the performed actions (clicking links, filling in the forms etc) in real-time which is not really convenient. Driver is a browser automation framework that allows us to perform various actions on web pages with a few lines of codeĪs you already know, Selenium Webdriver is used by default. One thing I prefer changing about the default testing suite is the web driver used for system tests.

In this series I will not use this form of writing, however.Īnother possible option is to utilize a third-party solution called Minitest-Rails that supports spec DSL as well. There are both generic and Rails-specific assertions that you can utilize - all of them are simple and self-explaining. Still, some developers may prefer specs over assertions (especially developers who are fond of RSpec). Minitest does allow you to run tests in a form of specs: describe Meme doĭescribe "when asked about cheeseburgers" doĭescribe "when asked about blending possibilities" do Note that the rails test command does not execute system tests as they are quite slow, so you’ll need to type rails test:system in order to run them (we’ll talk more about these tests later).Īnother thing to remember is that all tests are run under the test environment, so in order to provide some special configuration, tweak the config/environments/test.rb file.īy default Minitest relies on assertions that are written in the following way: assert user.save It is contains configuration for the system tests – that is, tests that perform simulation of the user’s actions with the help of Capybara and Selenium (or some other driver). *application_system_test_case.rb* is a new file that appears only in Rails 5.1+ applications. Of course, you are free to use FactoryGirl instead of fixtures but bear in mind that the latter solution is slower, though appears to be more flexible. It requires a file rails/test_help.rb and loads all the fixtures in alphabetical order from the corresponding directory. The test_helper.rb is the file that contains configuration for Minitest. Inside there are a bunch of folders with self-explaining names like controllers and models - these, as you’ve guessed, will store the tests for the corresponding components. In this case the default testing suite won’t be added and you are free to stick with any other solution like RSpec, for example.Īll right, so now let’s open the test directory and see what’s inside. Another new great feature is that the Database Cleaner gem is not required anymore - the testing database will be cleared for us automatically.īy the way, if you for some reason do not want to utilize Minitest, provide the -T flag when creating an application: $ rails new SomeApp -T These gems are used in BDD testing when we are simulating user’s behaviour so most developers were requiring those libraries anyways. Rails 5.1 has bring lots of nice improvements for us and enhancements of the testing suite is one of them.įor instance, you do not need to include Capybara and Selenium-webdriver into the Gemfile as they are present by default.

Okay, start off by creating a new Rails application: $ rails new MaxiTest

In this article you will learn how to set up and configure Minitest in order to start writing tests for your Rails application. Minitest is a default testing framework used in Rails that is both fast and powerful. There are multiple testing solutions available, including RSpec and Cucumber, but in this series of articles we will talk about Minitest. Also, when writing tests, you are effectively performing a code review: if some component is hard to test it might be due to its poor code structure. With a solid testing suite in place you can be much more confident when refactoring various parts of the application.Įven if something breaks, a failing test will notify you right away - this is much better than receiving a similar notification from an angry user who cannot log into the system anymore.

Testing is a very important (and sometimes quite complex!) part of a software development process.
