In this blog, let us discuss the Qt application and the challenges faced while testing it and also about QT application test Automation.

Qt application is a well-known graphical user interface (GUI) And a cross-platform application framework. It is primarily used to develop software that can operate on various platforms and operating systems. Qt application makes it possible to create applications with native-looking GUIs based on the operating system.

Qt application has an excellent collection of modules, like QtCore, QtGui and QtWidges, QtNetwork, QtWebkit, QtSQL, QtXML, QtXmlPatterns, etc… These platforms provide developers with all of the tools they need to create a cross-platform program with “state-of- the-art” GUI (Graphical User Interfaces). The program requires a variety of inputs for simplicity of usage. As it’s written in standard C++, it is generally categorized as a widget tool. And as a Qt application is written in C++, it is object-oriented and easily extendable via genuine component programming. Qt is used by some of the top companies like VLC player, Google Earth, K D E (Key Desktop Environment), Adobe Photoshop Album, Autodesk Maya, European Space Agency, etc.

There is an increased need for complicated (GUI) Graphical User Interface design, which may involve more testing. The importance of Qt application test automation is rising as the need for high-quality software grows in the software development industry.

Benefits of Qt application:

Qt application improves productivity and reduces go-to-market time, allowing applications to be used in long term. Developing an application with Qt simplifies the technological approach and, as a result, it helps to lower expenses. Saves time by deploying a single code across all screens and platforms. C++ programming gives developers more autonomy and the ability to work with several existing libraries. The code is built into native binaries that – execute at maximum performance (no need to use a virtual machine)

Qt also offers a very powerful IDE called Qt Creator that works on all platforms and provides the same development environment regardless of platform. Qt cross-platform software development makes it simple to create intuitive experiences for all users, irrespective of the system.

All these benefits of Qt applications are attracting Software Businesses to develop Qt applications. And the use of Qt applications can grow in the near future. Any company wants to provide an efficient app that is bug free, to make it bug free testing plays a crucial role. Testing a Qt application may not be easy. Now let’s see some challenges that are faced while testing a Qt application.

Qt application testing challenges:

You can create your test framework to test a Qt application, creating test frameworks but this is time-consuming. Suppose you consider utilizing a primary macro tool to capture the exact mouse/click steps. In that case, you must conduct the test in the same environment, which may result in a large number of flaky tests and makes it impossible to execute test scripts in multiple situations. When testing for an embedded device, Qt testing becomes much more complicated.

Why should we automate testing for a Qt application?

To meet the ever-increasing need for higher software quality, thorough end-to-end testing of software products has become standard practice. Manually testing each piece of software is a time-consuming process. Many software teams consider automating their testing process to avoid this.

Because of the challenges posed by a Qt application, it becomes more complex to test it, not all platforms can handle a Qt application. Only some frameworks like squish can handle it, even it involves scripting. algoQA is a platform that supports multiple ALM and other tools like Squish, Selenium, Appium and many more. algoQA reduces squish scripting efforts significantly, without writing the scripts not by record and play but by low code and no code principle, hence the scripts produced by algoQA are not flaky. The only manual intervention required while using algoQA is profiling.

By automating tests for Qt applications lot of time can be saved, the efficiency of the application can also be improved, and human testers are now free to do tasks that only humans can do. This helps in completing tests faster.

algoQA is the tool that you need for Test Automation for Qt application. algoQA enables automation of regression tests and system tests for Qt Widgets, Qt Quick, and QML applications, as well as the automation of interactions with embedded web content (Qt Webkit or Qt WebEngine). By leveraging algoQA, you get 5 times more productivity and save 80% time in the test automation cycle.


To conclude, Complex (GUI) Graphical User Interface design is becoming more necessary, which might also increase the demand for Qt applications. The importance of Qt application test automation may rise as the need for high-quality software may grow. Qt application test automation enables regular, rapid, and repeatable test runs, which helps in quality assurance. It helps in detecting regressions faster, making problems easier and less expensive to fix. It also helps in decreasing the risk of regressions being found late in the process, solving this lately can be more complicated and expensive.

algoQA is an End-To-End Test Automation Platform, leveraging Machine Learning. 100% test coverage & accuracy through automation, 80% test automation, and test maintenance cost saved by using algoQA.
