Open Source Cloud Computing Testing Tools

Testing tools and frameworks are infinitely useful when planning cloud architecture for many reasons

Testing tools and frameworks are infinitely useful when planning cloud architecture for many reasons.

“The confidence of a well-tested codebase brings the ability to deploy quickly, and often. Testing infrastructure assures that incremental changes to the codebase do not affect the overall application performance,” said Omid Rahmat, president, Burnside Digital.

One of the Rahmat’s favorite testing tools is rspec, used for ruby applications. Rahmat said it takes a "behavior-driven" approach to testing. “We follow the best practices of writing tests that explain what our code should do before writing it. This gives us a clear path to follow to implement solutions with great confidence and far fewer defects. Having that test and seeing it pass lets us know that we have written features to specification.”

Other popular testing tools include:

SoapUI. According to SoapUI Developer Erik Yverling at SmartBear, SoapUI is a functional testing tool used for testing web services and APIs and provides extensive support for various kinds of protocols such as SOAP, REST, HTTP, JMS and JDBC. “The reason why you want to use SoapUI, is that it's easy to get started with. It requires no programming knowledge, but is still very powerful and has extensive scripting support for all kinds of advance use cases."

LoadUI. LoadUI is the one of the world's most downloaded load testing software. It's free, open-source and easily extendable using Groovy. LoadUI can also integrate with SoapUI, letting you leverage existing functional tests when load testing. “LoadUI helps you answer the questions: Does it perform? Does it scale? What are the bottlenecks? Is the experience consistent for users on different continents?” said Henrik Olsson, Product Owner for LoadUI, with SmartBear.

TestMaker. As the Cyber Security and Information Systems Information Analysis Center website explained, “PushToTest TestMaker is a distributed test environment. TestMaker runs your tests on your test equipment, in a Cloud Computing environment, or both. TestMaker introduces specific commands to support automatic Cloud Testing. For example, identify a cloud testing service like Amazon EC2 in a TestScenario. TestMaker creates the TestNodes in EC2 instances, runs the test, retrieves the results, and takes down the EC2 instances. All in a ‘lights out’ manner for full Cloud Test automation.”
