# ocaml-bisect-ppx

[`Bisect_ppx`](https://aantron.github.io/bisect_ppx/) is a code coverage tool
for OCaml.  It helps you test thoroughly by showing which parts of your code
are *not* tested.  It is a small preprocessor that inserts instrumentation at
places in your code, such as if-then-else and match expressions.  After you
run tests, `Bisect_ppx` gives a nice HTML report showing which places were
visited and which were missed.

Usage is simple - add package `bisect_ppx` when building tests, run your
tests, then run the `Bisect_ppx` report tool on the generated visitation
files.
