Getting Started With iCuke

June 1st, 2010 1 Comments

Tonight I decided to give iCuke a try but I couldn’t find any good getting started guides.  iCuke is a BDD gem for cucumber that enables integration testing for the iPhone.  I’m familiar with using cucumber with Rails so getting going wasn’t terribly difficult but thought the pre-reqs should be a little more clear.

Here are five simple steps for getting started:

Step 1: Setup directories

$ cd path/to/your/iphone/app
$ mkdir features
$ cd features
$ mkdir support step_definitions

Step 2: Create cucumber.yml with the following content:
 default: -r support -r step_definitions .

Step 3: Create support/iphone.rb with the following content:
require 'icuke/cucumber'

Step 4: Enable the iPhone Simulator Accessibility Inspector in System Preferences
Step 5:  Create app.feature with the following content:

Background: 
  Given "MyApp" from "../MyApp.xcodeproj" is loaded in the simulator

Scenario: User views the Home screen
  When I tap "Home"
  Then I should see "Welcome"

RSpec Formating

August 25th, 2009 0 Comments

Using the -f switch with rspec you can choose several ways to format the output of your test results.  One that I recently found very interesting was

$ spec -fs spec

which will output something similar to this

CustomersController without a logged in user
- should not have access to view a list of customers.
- should have access to view a list of customers.

CustomersController with a user with permissions
- should view a list of customers.
- should view a customer.

The ’s’ format option outputs your specs as a specdoc, describing the behavior of the system under test.

Other formats include:

silent|l                                     : No output
progress|p                              : Text-based progress bar
profile|o                                  : Text-based progress bar with profiling of 10 slowest examples
specdoc|s                                : Code example doc strings
nested|n                                  : Code example doc strings with nested groups indented
html|h                                      : A nice HTML report
failing_examples|e               : Write all failing examples – input for –example
failing_example_groups|g  : Write all failing example groups – input for –example

Installing Ruby Oracle Libraries on Cygwin, OSX, and Linux.

July 22nd, 2009 2 Comments

A month or so ago I needed to connect a Rails site to an Oracle database from cygwin, osx, and linux (both 32 and 64 bit).

I’ve release the fruits of my labors as a collection of rakes files for each OS on github:

http://github.com/kevincolyar/ruby_oracle_libs/tree/master

Hopefully this will help someone else out.  Feel free to fork and let me know of any updates and improvements that are needed.
