Agile projects emphasize speed, iterative development, and close collaboration. But what does that mean for testing? First things first: Even in an agile environment, quality remains a key goal—it’s just ensured differently than in traditional projects.
In this article, you'll learn what really matters when it comes to testing in agile projects, what principles apply, and how testing can be effectively integrated into short development cycles.
Quality is no accident—not even in agile projects
In traditional projects, planning often takes a long time, and testing is done at the end. Agile methods such as Scrum or SAFe break with this approach: testing begins early and continues throughout the project. Errors are identified and corrected immediately, rather than at the end.
This requires a shift in thinking: Testing is not viewed as a separate phase, but rather as an integral part of the development process.
The Key Principles of Agile Testing
For testing to be successful in agile projects, clear principles and a clear understanding of roles are essential. The following are particularly important:
- Early Testing: Testing is considered from the very beginning—often even while the requirements are being written.
- Test-Driven Development: Methods such as TDD (Test-Driven Development) promote quality from the very beginning.
- Automation: Repetitive tests are automated to ensure speed and repeatability.
- Close Collaboration: Testers, developers, and product owners work closely together—sharing responsibility.
- Transparency and Feedback: Tests provide regular feedback on product quality—thereby enhancing the ability to steer the process.
Requirements and Tests: Two Sides of the Same Coin
Good tests require clear requirements—this applies just as much to agile projects as it does to traditional environments. Methods such as IREB-based requirements engineering ensure that requirements are precise, testable, and traceable.
In practice, this means:
- Requirements and acceptance criteria are formulated jointly
- Each sprint delivers potentially testable results
- Tests help to validate requirements, not just verify them
This creates a closed-loop process consisting of requirements, implementation, and quality control.
ISTQB: The Methodological Foundation for Agile Testing
The ISTQB Certified Tester offers a globally recognized certification model for professional software testing—including in an agile context. In the ISTQB training courses at SERVIEW , you’ll learn, among other things:
- What roles and processes testing fulfills in an agile team
- How to Make Requirements Testable and Translate Them into Test Cases
- How to Develop Agile Testing Strategies and Use Automation Effectively
- Which tools and techniques are state-of-the-art today
Conclusion: Testing is part of the agile culture
Agile development does not mean “less testing”—it means better, more targeted, and more integrated testing. When testing is incorporated from the very beginning, quality, efficiency, and customer satisfaction all improve. Anyone who wants to successfully manage agile projects should not view testing as a means of control—but rather as a strategic tool for quality assurance.
