# Fuzzing Tests # Fuzzing Tests
The fuzzing tests use the fuzzing templates from `nim-testutils`. This directory contains a set of subdirectories which hold one or more test cases that can be used for fuzzing.
The fuzzing test cases use the fuzzing templates from `nim-testutils`.
For more details see [the fuzzing readme of nim-testutils](https://github.com/status-im/nim-testutils/tree/master/testutils/fuzzing). For more details see [the fuzzing readme of nim-testutils](https://github.com/status-im/nim-testutils/tree/master/testutils/fuzzing).
Some of the subdirectories also hold corpus generation tooling in order to have some corpus files to start fuzzing from.

## How to run ## How to run
To start fuzzing a test case run following command: To start fuzzing a test case run following command:
```sh ```sh
# For libFuzzer # Rlp fuzzing with libFuzzer
ntu fuzz --fuzzer:libFuzzer rlp/rlp_inspect ntu fuzz --fuzzer:libFuzzer rlp/rlp_decode
# For afl # Rlp fuzzing with afl
ntu fuzz --fuzzer:afl rlp/rlp_inspect ntu fuzz --fuzzer:afl rlp/rlp_decode
``` ```
Or another example:
```sh
# ENR fuzzing with libFuzzer
ntu fuzz --fuzzer:libFuzzer enr/fuzz_enr
# ENR fuzzing with afl
ntu fuzz --fuzzer:afl enr/fuzz_enr
```
## Manual adjustments
The `ntu` application is still very limited in its functionality. Many of the underlying fuzzer functionality is not available for adjustment so you might want to configure the setup in a more manual way.
How to do this is briefly explained [here for afl](https://github.com/status-im/nim-testutils/blob/master/testutils/fuzzing/readme.md#manually-with-afl) and [here for libFuzzer](https://github.com/status-im/nim-testutils/blob/master/testutils/fuzzing/readme.md#manually-with-libfuzzer).
