[Treehouse Presents - Quick Tips: How to Run Tests in Ruby on Rails with Jason Seifer]

00:00:05,900 --> 00:00:12,570
Hi, I'm Jason. In this Treehouse quick tip, we're going to talk about how to run tests in Ruby on Rails.

3
00:00:12,570 --> 00:00:19,470
Tests are small, automated Ruby programs that automatically test different parts of our applications.

4
00:00:19,470 --> 00:00:25,420
After writing some tests, you can run them using the rake command-line application.

5
00:00:25,420 --> 00:00:29,690
Now let's take a look at how to run all of the tests in our application.

6
00:00:29,690 --> 00:00:36,800
If we wanted to run the tests in our application, we would type the word "rake" followed by the word "test."

7
00:00:36,800 --> 00:00:44,440
This would go through and run the different unit, functional, and integration test in our application.

8
00:00:44,440 --> 00:00:52,970
We can also omit the word "test" and just type "rake." By typing "rake" by itself, that will run the default rake task,

9
00:00:52,970 --> 00:00:56,960
which usually just happens to be test.

10
00:00:56,960 --> 00:01:07,890
If we wanted to run just the unit test, we could say "rake test:units." The same thing happens with functional and integration tests.

11
00:01:07,890 --> 00:01:14,920
There's one other interesting rake test command, which is "rake test:uncommitted."

12
00:01:14,920 --> 00:01:20,050
This will go through and run the test for any uncommitted files in your project.

13
00:01:20,050 --> 00:01:26,910
This is useful when you're working with other developers and don't want to commit that hasn't been tested.

14
00:01:26,910 --> 00:01:32,160
Finally, if you just want to run a single test, you can do that with Ruby command.

15
00:01:32,160 --> 00:01:38,630
Make sure to include the test directory and then type out the path to the test you want to run.

16
00:01:38,630 --> 00:01:42,660
I'm going to run the user test here. And there you go.

17
00:01:42,660 --> 00:01:49,010
As you can see, Rails makes it pretty easy to run our applications tests using the rake command.

18
00:01:49,010 --> 00:01:52,010
Thanks for watching this Treehouse quick tip.
