Pick Hypothesis if…

Hypothesis suits Python developers who want to specify acceptable behavior and let generated inputs probe their code. It is useful when tests need reproducible failures or sequences for stateful behavior.

JSVerify suits JavaScript developers who want generated inputs to check function properties, including asynchronous ones. It may also fit TypeScript projects that can work within the limitation on the type DSL in specs.
