German Testing Night Berlin 2025 – Three ideas for quality

The doors are closed, but the impulses of the German Testing Night in our Berlin office are still resonating. On November 19, 2025, more than 30 participants showed that the testing community in the capital was not only hungry, but above all that it values expert discussions. It was an evening full of good conversations with three outstanding presentations that shed light on the breadth of software testing.

Viktor Paland, Florian Fieber, Richard Seidl

The event was opened by Richard Seidl and Viktor Paland (both heise conferences GmbH and sigs.de respectively) and Florian Fieber (TestSolutions). This was followed by three presentations that highlighted the breadth and specific problems of software testing.

Muhittin Istanbulluoglu gives a presentation on AI-supported test automation

Lecture 1: AI-supported test automation in deep dive

Muhittin Istanbulluoglu, our Senior Test Automation Engineer, took us into the depths of AI-powered test automation. His findings: Traditional automation suffers from brittle locators and leads to flaky tests.

The solution: test what you can see - without locators. The AskUI solution works across all platforms. It uses artificial intelligence that understands the visual context. Test scripts are formulated using natural language prompts (NLP). The introduction to the NLP-driven AI agent called Caesr showed that the future of testing is based on intelligent visual perception.

Raveena Ranjith reports on accessibility testing

Lecture 2: Accessibility testing in practice

Raveena Ranjith, who shed light on accessibility testing practices, focused on user needs. Digital accessibility is not an option, but a necessity, underpinned by regulations such as the Barrierefreiheitsstärkungsgesetz (BFSG) and the EU Accessibility Act.

Raveena explained the four WCAG principles (Web Content Accessibility Guidelines): Content must be perceivable, operable, understandable and robust. She gave a practical demonstration of how barriers can be identified, for example by checking keyboard navigation, using screen readers or checking color contrast.

Dr. Dominic Steinhöfel talks about test data

Lecture 3: A look at the test strategy

The series of presentations was rounded off by Dr. Dominic Steinhöfel, CEO and co-founder of InputLab. The title of his presentation was: "Test data: The What, Why, and How." Dr. Steinhöfl highlighted the challenges of choosing the right test data. This must be realistically balanced between the requirements, GDPRspecifications and budget and time constraints. A mistake in the test data strategy not only leads to inadequate test coverage, but also harbors serious compliance risks. He presented a decision-making tool to systematically answer this complex question.

A successful evening that addressed the most important pillars of software quality - from future-oriented AI automation to compliance with important accessibility standards and strategic topics relating to test data.

Further events of this kind will follow and we very much look forward to your participation. We thank all participants for the exchange and look forward to shaping the future of software quality.

And as always, please feel free to get in touch.
