Company history

"Testing leads to failure and failure leads to understanding."

- Burt Rutan, aerospace engineer

 

Software testing is much more than just finding bugs – it is a process of gaining insight. It provides clarity on how systems truly operate, and makes quality measurable and tangible. Structured testing reveals where there is potential for optimization and which adjustments will ensure long-term stability.

At TestSolutions, we rely on fact-based, transparent quality assurance that identifies risks early and provides a solid foundation for well-informed decisions. For us, testing is not an end in itself – it is the key to great software.

Dr. Bernhard Kopp, CFO

"Quality is never an accident. It is always the result of intelligent effort."

- John Ruskin, polymath

 

Quality doesn't happen by chance – it is the result of well-thought-out processes, clear principles, and purposeful effort. Ensuring quality requires structure, objectivity, and a strategic view of the bigger picture.

With TestSolutions, companies gain a methodical, transparent approach that makes quality measurable from the very beginning. Our tests deliver reliable, economically relevant results – ensuring that software not only works, but remains dependable, efficient, and secure over the long term.

"You cannot inspect quality into a product; it is already there."

- William Edwards Deming, Quality Manager

Quality doesn’t come from checking after the fact — it results from a clearly defined and consistently applied quality approach. TestSolutions ensures that software is developed to be stable, efficient, and economically viable from the very beginning — not just at the end of the development process.

For TestSolutions, quality assurance means more than just finding bugs or executing test cases. Our approach makes quality measurable, controllable, and continuously improvable.

Testing not only shows whether software works, but also how stable, user-friendly, and maintainable it is in real-world use. This leads to robust applications that provide reliability for businesses, efficiency for processes, and a strong user experience.
