Fixturify provides a simple, reliable way to create and manage fixture files for testing in JavaScript projects. It allows you to define directory structures and file contents programmatically, simplifying test setup and ensuring consistent environments. Fixturify cleanly handles file creation, modification, and deletion, making it easy to reset your test environment between tests. This is especially useful for testing tools that manipulate files or directories. Its API promotes maintainable and readable tests by abstracting away the complexities of file system interactions.
