Case Study: Dr. Keil Informationstechnik achieves higher software reliability with QA Systems Cantata
A QA Systems Case Study
Dr. Keil Informationstechnik GmbH & Co - Customer Case Study
The customer, Dr. Keil Informationstechnik GmbH & Co, a consulting and software firm, was tasked by a major global telecommunications supplier to overhaul a critical network administration module. Their primary challenge was to meet an extreme reliability requirement that permitted a maximum of only 0.5 hours of downtime per year, necessitating a rigorous and comprehensive testing strategy for a complex C++ system. They appointed Michael Zeiner to lead the testing effort and needed a versatile tool to handle everything from unit to integration testing.
QA Systems provided the Cantata test tool as the main solution. Cantata's versatility allowed the team to move beyond unit testing to perform cluster, GUI, database, and client/server load testing efficiently. By using the tool, the team achieved high coverage metrics of 97% decision and 70% Boolean coverage, convincing project leaders to extend testing to ensure integrity. The solution minimized the need for multiple tools, saved significant effort, and was instrumental in building the required reliability into the system.
