Introduction#
Fuzzing is a software testing technique that involves providing invalid, unexpected, or random data as inputs to a computer program. The aim is to uncover bugs and vulnerabilities that might not be detected with conventional testing strategies.
Trident#
The Trident
testing framework equips developers with tools to efficiently develop fuzz tests for Anchor-based programs. It streamlines the fuzz testing process through automation and comprehensive support:
- Automatically parses Anchor-based programs to generate necessary implementations for deserializing instruction accounts.
- Generates templates for developers to customize according to the specific needs of their fuzz test scenarios.
- Offers derive macros to effortlessly implement required traits, reducing manual coding efforts.
- Includes a bank client and helper functions for simplified account management during testing.
- Provides a Command-Line Interface (CLI) for executing and debugging fuzz tests with ease.
Trident
is built for customization, enabling developers to tailor their fuzz tests by adjusting:
- Execution Order of Instructions: Test different sequences and their effects on the program to uncover sequence-related vulnerabilities.
- Instruction Parameters: Identify how variations in inputs influence program behavior, testing for robustness against a wide range of data.
- Instruction Accounts: Explore the impact of different account states on the software's functionality, ensuring comprehensive account testing.
- Comprehensive Testing: Conduct thorough and effective fuzz testing by combining any of the above aspects.
This framework supports a detailed and methodical approach to fuzz testing, facilitating the identification and remediation of potential vulnerabilities in software applications.
