Ruby SDK Version 2 and Memoization

Version 1 of the AWS SDK for Ruby (aws-sdk gem) provides a higher-level abstraction for working with AWS resources. These resources can be used to get information about AWS objects and operate on them as well. For example: AWS.ec2.instances.each do |i| puts i.instance_id + ‘ => ‘ + i.status.to_s end The problem with the example […]

Parameter Validation

One of my favorite features of version 2 of the AWS SDK for Ruby (aws-sdk-core gem) is the new parameter validation system. One of the challenges in using an API library is understanding how to specify request parameters. During development stages it is common to make mistakes and to generate errors. Using the version 1 […]

Flexible Gem Dependencies

Using SimpleCov with Multiple Test Suites

It can be helpful to generate coverage reports when testing software. While coverage reports do not guarantee well tested software, they can highlight were test coverage is lacking. This is especially true for legacy, or un-tested projects. Recently I ran into a situation where I wanted to generate a coverage report, but the project used […]
