Running Tests in Ruby on Rails

[Treehouse Presents - Quick Tips: How to Run Tests in Ruby on Rails with Jason Seifer] 0:00 Hi, I'm Jason. In this Treehouse quick tip, we're going to talk about how to run tests in Ruby on Rails. 0:05 Tests are small, automated Ruby programs that automatically test different parts of our applications. 0:12 After writing some tests, you can run them using the rake command-line application. 0:19 Now let's take a look at how to run all of the tests in our application. 0:25 If we wanted to run the tests in our application, we would type the word "rake" followed by the word "test." 0:29 This would go through and run the different unit, functional, and integration test in our application. 0:36 We can also omit the word "test" and just type "rake." By typing "rake" by itself, that will run the default rake task, 0:44 which usually just happens to be test. 0:52 If we wanted to run just the unit test, we could say "rake test:units." The same thing happens with functional and integration tests. 0:56 There's one other interesting rake test command, which is "rake test:uncommitted." 1:07 This will go through and run the test for any uncommitted files in your project. 1:14 This is useful when you're working with other developers and don't want to commit that hasn't been tested. 1:20 Finally, if you just want to run a single test, you can do that with Ruby command. 1:26 Make sure to include the test directory and then type out the path to the test you want to run. 1:32 I'm going to run the user test here. And there you go. 1:38 As you can see, Rails makes it pretty easy to run our applications tests using the rake command. 1:42 Thanks for watching this Treehouse quick tip. 1:49
