According to StatCounter, the demand for PC software is about 43.48%, which indicates the need for desktop developers in the IT industry. One of the main problems in software development is bugs found at the release stage. The only ones who can optimize the product quality are SQA specialists, or simply testers. It’s obvious that the QA industry has changed a lot over the past decades.
Initially, the development methodology did not allow for quickly tracking bugs and fixing them during sprints. Additional resources and time were spent, and testing was performed mainly by programmers themselves and not outsourced. Of course, it negatively affected the quality of final products. With automated desktop apps testing, most routine processes have faded into the background, but new problems and challenges for QA personnel have appeared.
The ZappleTech expert team analyzed the QA services market and prepared for you a short report on effective working methods. In this material, you will learn how to automate test desktop apps and which tools are best used for this purpose.

The history of QA: from the Stone Age to modern methods
Let’s remember the testing process in the 1980s, 90s, and even in the early 2000s. It all started with the classics, namely the Waterfall model, which was replaced by more modern Scrum and RAD. They all brought a lot into the SQA process. Let’s consider their features and testing methods:
Waterfall: testing is provided after the completion of each module. If bugs are found, development stops until the problem is solved. After this, the product is integrated into the finished system and released. As a result, compatibility issues may occur. They can be resolved after the release only.
Scrum: The testing process starts from the first days of development. It is synchronized with the sprints of programmers and designers and helps to quickly fix bugs without waiting for the project release. The main disadvantage is the dispersion of the QA team’s forces for testing, making cases, and communication. The staff often makes mistakes because of overwork.
RAD: since application modules are developed simultaneously, the QA team is divided into groups that check the entrusted area for errors, communicating with programmers. Everything should be retested before being integrated into a common product. After the release, a multifunctional test checks the performance of the entire application.
Although the methods are different, the main purpose of testing does not change. Optimization of user experience and performance of the final product is a priority task for QA specialists. The quality of the released application depends only on their care and thoroughness.
Responsibilities of QA Teams
Technologies evolve, and methodologies too. With the transition from Waterfall to Scrum, and then to Agile and DevOps, developers managed to effectively establish the responsibilities of all team members and delegate some operations to third-party contractors. A lot of time has passed, but the basic principle of QA testing remains the same.
Now the responsibilities of testers include:
- Writing cases considering the specification, product direction, and programming language.
- Creation of a test plan and synchronization with sprints and software development stages.
- Development of scenarios to test the functionality and interaction of all interface elements with units.
- Description of found errors, formation of bug reports, sending them to programmers.
- Control over the correction of pressing problems by developers and repeated checks of finished components.
- Preparing regression testing for each development stage.
- Manual and automated desktop apps testing with native tools and web technologies.
At the same time, the QA process is almost identical both for startups with a small budget and for large companies with strict product requirements. The trend is user experience, which means that the teams of testers focus on the software functionality, logical control, and operation of the interface under normal conditions and deviations from standard scenarios.
What is automated desktop apps testing
If you are interested in QA and desktop software, you know that the testing process includes manually checking each component for defects. Now the industry is looking at techniques from young but promising market players, i.e., web developers. Their scripts for automating routine checks are gradually integrated into programs, modernized, and developed.
The more complex the software, the more resources are involved in testing it. With modern tools, this process is packaged into compact scripts and run in cycles. It is called automated desktop apps testing. To automate QA, you need a background and understanding of tools, a programming language, and a little imagination and creativity.
How testing affects the final quality of an IT product
There is a statement that has become the axiom of testing IT products: “The more bugs are revealed during the development, the less money will be spent on fixing them after release.” We agree with this. We have been providing QA services for a long time, so we know for sure the cost of fixing the software after release.
Automated desktop apps testing process
It is difficult to single out common instructions for automated desktop apps testing because it involves many programs that contain different algorithms and commands. Nevertheless, the common things can be noticed, for example, preparing for testing, generating reports, etc.
Let’s walk through this procedure step by step:
- Making scenarios. Creating a test condition, entering the needed parameter, the value, and the expected result.
- Writing scripts. Describing the required actions and determining the sequence and cyclicality.
- Authenticity check. Checking the case against the script body, eliminating differences, optimizing the executable code, establishing connections with units, etc.
- Running the test. Making operational edits, sending the script to RAM, running the scripts over and over again.
- Analysis of reporting. Reviewing logs saved in text files and checking them for compliance with the expected results.
- Correction and redoing. Changing code in the case of bugs and retesting.
As a result, bugs must decrease to zero. The tested section of the program connects with the main body, and development continues.
