Verification and Testing
Table of Content
In this course, we teach various advanced methods to test and verify software and hardware. Instead of classical unit tests, we present techniques for automatic detection of bugs with little user-effort and methods to prove the correctness of a program independent of concrete input values.
The lecture starts with dynamic methods to detect and locate potential bugs related to concurrency or invalid memory accesses. Those bugs are hard to find with unit tests because they seem to show up randomly and are hard to reproduce. In the following lectures, we move on to static methods. Within these chapters, we show you how to prove the correctness of a program formally. Finally, the lecture ends with a session where we present current research topics to you. If you are interested in a master project, thesis, or internship on one of these projects, don’t hesitate to contact us!
The content of this lecture includes:
- Eraser algorithm to detect race conditions
- Locktree algorithms to identify potential deadlocks
- How Valgrind finds invalid memory accesses
- Static Analysis
