FAQPage Schema

How do I write and run fuzz tests for Vyper contracts?▼

To run fuzz tests for Vyper contracts, generate test_*.py files using Titanoboa and Moccasin patterns. This approach automates comprehensive test workflows, supplying randomized inputs to validate contract logic and edge cases efficiently.

What's the best way to manage test fixtures for Vyper smart contracts?▼

The best way to manage Vyper test fixtures is by defining contract deployments within a tests/conftest.py file. This centralizes deployment logic and streamlines test creation using Titanoboa and Moccasin tooling across your test suite.

Can I generate gas profiling and coverage reports for Vyper tests?▼

Yes, you can generate gas profiling and coverage reports for Vyper tests. By applying Titanoboa and Moccasin workflows to your test_*.py files, the skill automates comprehensive coverage assessment and gas profiling outputs.

Does this Vyper testing workflow support pranking and private member access?▼

Yes, this Vyper testing workflow supports pranking and private member access. It leverages Titanoboa and Moccasin to automate testing of blueprint/factory patterns, access control, and token logic while allowing internal state manipulation.

Do I need specific directory structures and tools to test Vyper contracts?▼

Yes, testing Vyper contracts requires the boa and Moccasin tooling. You must organize your test files under a tests/ directory and place your deployment fixtures within tests/conftest.py to execute the automated workflows.
