Start Fuzzing#

To start writting fuzz tests, you need to initialize Trident in your Anchor-based workspace.

trident init

If you have already initialized Trident, you can add a new fuzz test using:

trident fuzz add

Trident creates a new fuzz test template in the trident-tests directory, with the following structure:

project-root
├── trident-tests
│   ├── fuzz_0 # particular fuzz test
│   │   ├── instructions # instructions folder
│   │   ├── transactions # transactions folder
│   │   ├── test_fuzz.rs # the binary target of your fuzz test
│   │   ├── types.rs # the types of your fuzz test
│   │   └── fuzz_instructions.rs # the definition of your fuzz test
│   ├── fuzz_1
│   ├── fuzz_X # possible multiple fuzz tests
│   ├── fuzzing # compilations and crashes folder
│   └── Cargo.toml
├── Trident.toml
└── ...

Instructions folder contains the instructions that can be used in the fuzz test.

Transactions folder contains the transactions that will be used during the fuzzing, each transaction can contain one or multiple instructions, based on the developers choice. By default there is only one instruction in each transaction.
