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 realtime 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.

- ControlDesk
- Real-time hardware
Course Content
- 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
- Structure of real-time tests (initialization phase, time synchronous execution)
- Accessing model variables from real-time tests
- Test modularization
- Relation between Python scripts on the PC and on the real-time platform
- Libraries for test automation by real-time testing (e.g., for variable access, and data exchange between independent tests)
