Testing open source software can be a great way to sharpen your manual testing skills, especially if you want experience with mature desktop applications. The key is to approach it like a real-world QA effort: understand the product, learn how the project is run, and focus your time where it will create the most value.
Start by checking whether the project is worth your time
Not every open source project is equally useful for practicing testing. Before you invest effort, look for these signs:
- An active issue tracker so you can see how bugs are reported and handled.
- Regular issue resolution so you can practice verifying fixes, not just finding problems.
- Clear release notes or change logs so you know what changed in the latest version.
- A manageable build and install process so you can reproduce issues without losing time on setup.
If a project rarely gets bug reports or fixes move very slowly, it may be better for learning culture and communication than for practicing hands-on QA workflows.
Work like an end user, but think like a tester
For open source projects, there is often no formal test plan. That means you may need to create your own structure. A practical approach is to combine end-user behavior with systematic testing:
- Read the latest release notes and identify changed areas.
- Test the main user flows first, especially the features most people rely on.
- Explore edge cases and error handling, not just the happy path.
- Try both functional testing and, where relevant, basic performance checks.
This is especially useful for desktop applications, where installation, update behavior, file handling, and system integration can be just as important as core functionality.
Focus on the most valuable testing activities
If you are contributing to a community project, your time is often best spent on work that helps the project and builds your own experience at the same time. Good examples include:
- Reproducing known bugs to confirm they still exist or are truly fixed.
- Verifying fixes after a new build or revision is published.
- Writing a small but clear test plan for a feature area that lacks documentation.
- Reporting issues with strong detail, including steps to reproduce, expected behavior, actual behavior, and environment details.
A well-written test plan can be especially valuable in volunteer-driven projects because it creates continuity when contributors change over time.
How to choose the right project
If your goal is to practice testing skills, a good candidate project usually has the following:
- Enough users to generate meaningful feedback.
- Active development and bug fixing.
- Clear communication channels with maintainers.
- A desktop or web interface with realistic user workflows.
Large, widely used projects often have more structured testing, while smaller projects may give you more freedom to contribute directly. Both can be useful, but they teach slightly different lessons.
A simple workflow you can follow
- Read the project’s documentation and recent release notes.
- Check the issue tracker for open and recently fixed bugs.
- Pick one feature area and define a short test checklist.
- Run through the checklist as a user would.
- Log anything unusual with clear reproduction steps.
- Re-test after fixes or new builds are available.
This approach keeps your work focused and makes it easier to compare results across versions.
Practical example
Imagine a desktop note-taking app with recent changes to file import and sync. A useful test pass might include:
- Installing the app on a clean machine.
- Importing files of different sizes and formats.
- Checking whether sync works after disconnecting and reconnecting the network.
- Verifying that error messages are understandable when imports fail.
- Confirming that a bug fix really works in the next build.
That kind of testing is realistic, repeatable, and valuable to the project.

Where Repeato can help
If you later want to speed up repetitive checks on desktop-like workflows or app interfaces, Repeato can be a practical next step. It is a no-code test automation tool for iOS, Android, and web apps, with fast test recording and easy test maintenance. Because it uses computer vision and AI, it can help reduce the effort of repeating the same verification steps while you focus on exploratory testing and issue analysis.
In short: start with active projects, test like a real user, document what you learn, and build from there. That is the most useful way to grow your testing skills in open source environments.
