+# cargo fuzz
+
+This repository contains the fuzz targets for the summa codebase. Go to the root of the directory and follow thsi path:
+`summa/zk_prover/fuzz` and then run `cargo fuzz --help`. If this does not work then follow the setup.
+
+### SetUp
+Go to the following directory `summa/zk_prover/fuzz` and run:
+```
+cargo install cargo fuzz
+```
+To test a function, create a new fuzz target:
+```
+cargo fuzz add <fuzz_target_name>`
+```
+To check all fuzz targets, run:
+```
+cargo fuzz list
+```
+To run fuzz tests on a target, run:
+```
+cargo fuzz run <fuzz_target_name>`
+```
+
+### How to write tests
+
+Refer `fuzz_targets/operation_helpers.rs` 
+
+``` rust
+fuzz_target!(|data: &[u8]| {
+   // code goes here
+}
+```
+This function generates a random bytes array that can be used to pass as inputs in any function you wish to fuzz.
+In order to import a function, write: 
+``` rust
+use summa_solvency::merkle_sum_tree
+```
+at the top and write the function by providing the specific path
+
+For example:
+``` rust
+let username_as_big_uint = merkle_sum_tree::utils::big_intify_username(username);
+```
