ProVerB: Program Verification Book


ProVerB is a project aimed at explaining program verification tools to practicing software developers, and at helping them to find they way around the available tools, clearly and briefly summarising the main purpose of the tool, its current status, relations to other tools, etc. Read more about the project on the credits page.

We classify all tools in this book as belonging to one of the six levels:

The PV-hierarchy does not represent how “worthy” or “important” a tool is, merely how much it expects and demands of its end user, and what it can offer back. In many cases having a lower-PV-level tool is more preferable because it is easier in use and is less ambitious about the effort investment. Often tools of a lower PV-level are built “on top” of tools of higher level which they run as a backend.
