38 CHAPTER 2 Testing saves your bacon
Listing 2.24 Terminal
Feature: My Account
In order to manage my account
As a money minder
I want to ensure my money doesn't get lost
Scenario: Taking out money
Given I have an account
And it has a balance of 100
When I take out 10
Then my balance should be 90
This output appears in color in the terminal with the steps of the scenario in yellow, 7
followed by a summary of this Cucumber run, and then a list of what code you used to
define the missing steps (not shown in this example output), again in yellow. What
this output doesn’t tell you is where to put the step definitions. Luckily, this book does.
All these step definitions should go into a new file located at features/step_definitions/
account_steps.rb. The file is called account_steps.rb and not account.rb to clearly separate
it from any other Ruby files, so when looking for the steps file, you don’t get it
confused with any other file. In this file, you can copy and paste in the steps Cucumber
gave you, as in the following listing.
Listing 2.25 features/step_definitions/account_steps.rb
Given /^I have an account$/ do
pending # express the regexp above with the code you wish you had
end
Given /^it has a balance of (\d+)$/ do |arg1|
pending # express the regexp above with the code you wish you had
end
When /^I take out (\d+)$/ do |arg1|
pending # express the regexp above with the code you wish you had
end
Then /^my balance should be (\d+)$/ do |arg1|
pending # express the regexp above with the code you wish you had
end
If you run cucumber features again, you’ll see that all your steps are defined but not
run (signaled by their blue coloring) except the very first one, which is yellow because
it’s pending. Now you’re going to restructure the first step to make it not pending. It
will now instantiate an Account object that you’ll use for the rest of this scenario.
7 If you’re running Windows, you may need to install ANSICON in order to get the colored output. This process
is described at https://github.com/adoxa/ansicon, and you can download ANSICON from http://adoxa
