Souvlaki: Composable React Test Wrappers

Souvlaki is a TypeScript-first library designed to simplify testing React components that rely heavily on context or multiple providers. It offers composable utilities to create and combine test wrappers, abstracting away the boilerplate often associated with setting up complex testing environments for components using Redux, React Router, Apollo, or custom contexts. The package is currently at version 0.3.1. While the author notes it's 'more or less finished' and doesn't receive regular updates, it is actively used and considered maintained, implying a stable but slow release cadence. Its key differentiator is simplifying the management of multiple providers in tests, offering a cleaner alternative to manually creating custom `render` functions or nesting providers directly in every test, thereby promoting more maintainable and readable test suites when used with React Testing Library.
