The rv tool needs automated testing to catch regressions and verify correct functionality across different usage scenarios. Add selftests that validate monitor listing (including containers and nested monitors), monitor execution with different configurations (reactors, verbose output, tracing), and trace output format for both per-task and per-cpu monitors. Error handling paths are also tested. Tests use a shared engine for common patterns.

RV: Runtime Verification
Runtime Verification (RV) is a lightweight (yet rigorous) method that
complements classical exhaustive verification techniques (such as model
checking and theorem proving) with a more practical approach for
complex systems.
The rv tool is the interface for a collection of monitors that aim
analysing the logical and timing behavior of Linux.
Installing RV
RV depends on the following libraries and tools:
- libtracefs
- libtraceevent
It also depends on python3-docutils to compile man pages.
For development, we suggest the following steps for compiling rtla:
$ git clone git://git.kernel.org/pub/scm/libs/libtrace/libtraceevent.git
$ cd libtraceevent/
$ make
$ sudo make install
$ cd ..
$ git clone git://git.kernel.org/pub/scm/libs/libtrace/libtracefs.git
$ cd libtracefs/
$ make
$ sudo make install
$ cd ..
$ cd $rv_src
$ make
$ sudo make install
For further information, please see rv manpage and the kernel documentation:
