Software testing for the CTA observation execution system

The Cherenkov Telescope Array (CTA) will be the next-generation ground-based instrument for detecting veryhigh energy gamma rays. It will consist of roughly 100 telescopes of different sizes and designs. In addition, a variety of auxiliary instrumentation will be part of the array. The Observation Execution System (OES) is the software system in charge of operating and monitoring all telescopes and devices, applying short-term observation schedules depending on the hardware status and environmental conditions and handling the data. Motivated by the wealth of tasks to accomplish and requirements to fulfil, a software development procedure is conceived for the development of OES. Part of this development process is the application of software testing procedures. These procedures range from unit tests up to system tests and stress tests. In this contribution, the software development process and the application of static and dynamic code analysis tools are described.
