# QA and testing Quality assurance (QA) testing is critical to the reliability and stability of Ubuntu, and is an excellent way to get started as a contributor. Testing doesn’t require any special setup – it can be as simple as running the latest version of Ubuntu, reporting any issues you find as bugs, and helping to manage any bugs you find until they are fixed. If you’re feeling adventurous, you can also help test out new pre-release versions of Ubuntu! * [Report a bug](https://documentation.ubuntu.com/project/contributors/qa-and-testing/report-a-bug.md) * [Application testing](https://documentation.ubuntu.com/project/contributors/qa-and-testing/application-testing.md) * [Manual ISO testing](https://documentation.ubuntu.com/project/contributors/qa-and-testing/iso-testing.md) * [Hardware testing](https://documentation.ubuntu.com/project/contributors/qa-and-testing/hardware-testing.md) * [Upgrade testing](https://documentation.ubuntu.com/project/contributors/qa-and-testing/upgrade-testing.md) * [Pre-release testing](https://documentation.ubuntu.com/project/contributors/qa-and-testing/pre-release-testing.md)
