100+ Open Source/Free Functional Testing Tools

It is very important to make sure that your application functions as expected. There may be times that you add one little piece of code and all of a sudden other parts of the application no longer works. You may not have time/capacity to manually go back and regression test all the pieces of your application to make sure they are up to par. Companies use a variety of different testing tools for regression testing. There are lots of tools out there from very expensive to open source.

Below is a list of some open source/free tools that may come in handy.

Please keep in mind that every application is different so the tool you pick from one application may not be the same tool that you pick for another. My advice would be to pick a tool that can meet most of your current and near future needs.

• Abbot Java GUI Test Framework: The Abbot framework provides automated event generation and validation of Java GUI components, improving upon the very rudimentary functions provided by the java.awt.Robot class (A Better ‘Bot). The framework may be invoked directly from Java code or accessed without programming through the use of scripts. It is suitable for use both by developers for unit tests and QA for functional testing.
• actiWate: Java-based Web application testing environment from Actimind Inc. Advanced framework for writing test scripts in Java (similar to open-source frameworks like HttpUnit, HtmlUnit etc. but with extended API), and Test Writing Assistant - Web browser plug-in module to assist the test writing process. Freeware.

Behind the scenes, they are linked to the system under test and therefore do not go out-of-date. If a change is made to the system’s behaviour then the tests associated with the relevant specification will fail and let you know.Requirement: Java 1.5 or above
• Crosscheck: Framework for verifying your in-browser javascript. It helps you ensure that your code will run in many different browsers such as Internet Explorer and Firefox, but without needing installations of those browsers. The only thing you need is a Java Virtual Machine.Requirement: Java Virtual Machine

In contrast to standard diff, it will show the number of the record where the difference occurs, the column number, and (if provided) the fieldname which is different. The separator can be set to any value you want, not just a comma. It also provides support for multiple column keys, the ability to ignore case and trim leading/tailing spaces, and the ability to ignore selected columns such as timestamps. Requirement: Everywhere you can install perl
• CubicTest: A graphical Eclipse plug-in for writing Selenium and Watir tests. It makes web tests faster and easier to write, and provides abstractions to make tests more robust and reusable.

Using mockito, you can verify what you want. Using expect-run-verify libraries you are often forced to look after irrelevant interactions. Mockito has very slim API, almost no time is needed to start mocking. There is only one kind of mock, there is only one way of creating mocks. Just remember that stubbing goes before execution, verifications of interactions go afterwards. Requirement: Java
