Hi everyone!
I’m very pleased to announce this exciting new release of Ortac packages!
Ortac is a set of tools for dynamic verification of Gospel formal specifications of OCaml code.
You can find the project on this repo and install the released packages via opam
.
Released packages are:
ortac-core
ortac-runtime
ortac-runtime-qcheck-stm
ortac-qcheck-stm
ortac-dune
But running:
$ opam install ortac-qcheck-stm ortac-dune
should be enough to install what is necessary.
Apart from some fixes, this release brings three main improvements to the Ortac/QCheck-STM mode.
The first one is about user experience. This is a two-parts improvement as we:
- move to a module-based configuration to reduce the number of arguments to give
ortac qcheck-stm
while increasing the flexibility of configuration (see documentation for more information) - release the Ortac/Dune plugin which generates the dune rules necessary to generate and run the tests (see README for usage).
With these two improvements, we believe that you have a very good excuse for not writing tests: it is very easy to generate them!
The second improvement is related to the supported subset of Gospel, mainly about how you can express the logical model for your OCaml types: you don’t have to limit yourself anymore to the Gospel standard library.
Finally, some work has been put on extending the coverage of the generated tests: functions without any SUT argument and functions mentioning tuples are now included in the tested values.
Happy testing!
