I’m not really that good at testing. So what, so are a lot of people. Having some tests is better than none! And, the way testing tutorials are written can seem really complex and scary. Today I started thinking about the simplest possible way to get started with web app testing.
When I’m getting back into a project after not working on it for a while, I just want to know whether the application works. I want to know whether it will run on my development environment, even if I’m on a new machine. I have three computers that I use at various locations so this is important to me.
So for me the simplest possible test would be:
Here’s how I do it with cucumber:
If you haven’t installed the cucumber gems yet, put this in your config/test.rbfile.
If you haven’t cucumber set up yet, run
script/generate cucumber
Then, create the file below:
File: features/homepage.feature
Feature: View homepage for app In order to make sure the app loads As a user I want to see the home page Scenario: Homepage should say Search When I go to the homepage Then I should see "Search"
Tip: none of what you write in the Feature section really matters. It’s just for you or your client’s benefit.
Then, run
cucumber features
You should get the following output:
:> cucumber features
Feature: View homepage for app
In order to make sure the app loads
As a user
I want to see the home page
Scenario: Homepage should say Search # features/homepage.feature:6
When I go to the homepage # features/step_definitions/webrat_steps.rb:10
Then I should see "My Telltale Text" # features/step_definitions/webrat_steps.rb:118
1 scenario (1 passed)
2 steps (2 passed)
Some cool things about this: “the homepage” is something that cucumber / webrat understands out of the box. See features/step_definitions/webrat_steps.rb for how to define other custom route names. And also, “I should see “something in quotes” is out of the box cucumber goodness.
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness. That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed.
Not all corporations are created equal, as our conservative supreme court seems to think. It’s time to use our people power to set that straight. And, while we’re at it, let’s set up a direct democracy party too! The Australians have already made a first step!
