Squish Highlights 

Multi-platform and device support

No changes to the application needed

Dedicated support for all Qt widgets and controls

Support for embedded web content

Access to all properties and APIs

Support for hybrid Qt and native Windows GUIs

What’s really key for us, having to do end-to-end integration testing and not normally having access to all the source code, is a tool like Squish that can talk to an application on Linux and one on Windows…it provides exactly what we need.



Exploring Skyguide’s test automation journey with Squish

We had the opportunity to speak to Skuguide's Test Automation Engineers, Duncan Fletcher and Geoffroy Carlotti, to learn more about the company's extensive use of Squish to test a diverse range of applications. 

Notably, Skyguide's engineers adhere to a Behavior-Driven Development (BDD) paradigm in their automation endeavors. This methodology revolves around creating stories in a common language to articulate an application's expected behavior. 

This unique approach allows both technical and non-technical users to contribute to the creation of feature descriptions and tests. The engineers we spoke to play a crucial role in establishing the foundational aspects of this BDD framework for other teams within Skyguide, enabling both technical and business professionals to actively participate in the realm of test automation.


A deep dive into advanced automation techniques at Skyguide

Engineers at Skyguide are no strangers to leveraging advanced automation techniques, particularly with Squish. In a specific application, as described by Duncan and Geoffroy, a sophisticated multi-pronged approach is employed.

This approach combines localized Optical Character Recognition (OCR) with localized image search and Windows object recognition. The application under scrutiny, crafted in C++ and operating on Windows, constitutes the flight radar system crucially positioned in front of air traffic controllers.

An essential aspect of this radar system is the intricate algorithm determining how a flight appears on the screen. According to Geoffroy, there are numerous rules governing the proper display of a flight on the radar screen, including the adherence to specific color rules to ensure the air traffic controller's focus is not diverted. 

Squish has proven instrumental in streamlining the testing process for this application through automation. Geoffroy emphasized the enormity of the task, stating, "It's impossible to test all these cases manually, so this is huge."

The engineers highlighted the general diversity of applications tested within the company, making Squish stand out for its remarkable ability to test such a varied set of applications within a unified framework.

The fact that we’ve reduced the needed framework down to one tool is one reason we chose Squish.



Harmony in testing Skyguide's inclusive BDD approach and automation aspirations

Technical and non-technical project stakeholders alike reap the benefits of the Behavior-Driven Development (BDD) approach implemented by Skyguide's engineers. 

At its core, Duncan and Geoffroy are shaping the BDD framework to be accessible to both testers and requirements authors. This approach ensures that every team member can easily access, comprehend, and respond to test results. 

The engineers aspire to broaden this involvement by actively engaging more end-users and business professionals in BDD scenarios. The ultimate goal is to approach GUI testing in a holistic and comprehensive manner that encompasses all facets of the business.

While Duncan acknowledged that the team still conducts a substantial portion of manual tests, Skyguide is progressively shifting its focus towards automation. 

Another huge benefit is that [with BDD] there is living documentation.
