+Fuzz Testing
+============
+
+To enable fuzz targets compilation, add `--enable-fuzztargets` to configure.
+
+.. note:: This changes various parts of Suricata making the `suricata` binary
+          unsafe for production use.
+
+The targets can be used with libFuzzer, AFL and other fuzz platforms.
+
+
+Running the Fuzzers
+-------------------
+
+TODO. For now see src/tests/fuzz/README
+
+Reproducing issues

+Oss-Fuzz
+--------
+
+Suricata is continuesly fuzz tested in Oss-Fuzz. See https://github.com/google/oss-fuzz/tree/master/projects/suricata

+Unittests
+=========
+
+Unittests are a great way to create tests that can check the internal state
+of parsers, structures and other objects.
+
+Tests should:
+
+- use FAIL/PASS macros
+- be deterministic
+- not leak memory on PASS
+- not use conditions
