Squish's Extensibility and Integratability

Today I’d like to write about some of Squish’s features which are not so well known but which makes Squish a really powerful GUI testing solution.

Extensibility: When we started to create Squish, our main focus was to support all standard components of the supported GUI technologies (Qt, Swing, SWT, etc.) very well. But soon we found that in nearly every GUI application custom components are used. These are often complex and interactive controls visualizing data in some way. While basic support for all custom components can be provided out-of-the-box (and is provided that way by Squish), there is no way a GUI testing tool can know all internals (such as internal objects) of such custom controls and support that in a robust way.

This made us think about extension capabilities. The first Squish edition where we offered an extension API was Squish for Web- the automted GUI testing tool for web applications. The reason for that is probably that esp. in the world of AJAX GUIs nearly all controls used are custom controls.

This extension allows users to implement a few functions in JavaScript to let Squish know how to query internal information of custom AJAX controls. That way every custom AJAX control can be supported equally well as standard HTML and AJAX controls already known to Squish.

Later we introduced a similar mechanism for our Squish for Java tool, which features automated testing of Java GUIs such as Swing, AWT, SWT and Eclipse RCP. Here we provide a few Java interfaces which you need to implement for your custom Java controls to allow Squish to drill down into the details of your custom controls.

Since these extensions solve many problems of GUI testing, we are now introducing similar extension APIs for our Squish for Qt edition. Also our new Squish edition for testing native Windows applications, which will be part of the upcoming Squish 4.0, will be completely built on this extension mechanism even internally.

Integratability: Many vendors of testing tools want to completely lock their users into their world. So they come with the complete tool set needed to automate the QA. We early realized that GUI testing is just one part of the whole QA process and also saw that most of our users already have automation systems in place for their unit testing. So they usually prefer to integrate Squish into their existing automation system instead of setting up a completely separate automation just for GUI tests.

So we decided to focus on making Squish easy to integrate instead of developing our own test management solution. To allow that we provided easy-to-use command line tools to start and control Squish test runs and generate an easy-to-process XML report from any test run. This allows for easy integration.

In addition we now also offer ready-made integrations for CruiseControl, Maven, Ant, Eclipse TPTP, HP Quality Center and more so Squish can be used as part of the whole test automation regardless of the tools in use.

We will also release our own test management system, which we use internally, eventually. But this will be just another way to do it and not replace our integration. Rather the opposite But we will always ensure that Squish stays easy to integrate since we really think that our users should have the choice what they want to use.
