Real-Time Testing

Real-time hardware can be accessed via an interpreter running on the processor board. Since the interpreter is executed at the same rate as the real-time application, it can be used to perform real-time tests. This training course provides an introduction to programming real-time tests based on the Python programming language. Course participants will discuss standard applications and implement them in practical examples.

Course Contents

• The necessity of real-time tests
• Workflow of real-time testing (from script to executable real-time test, test management)
• Introduction to special Python programming elements for real-time testing
