lenmymock

lenmymock is a JavaScript library designed for mocking dependencies in unit testing. It allows developers to replace real modules or objects with mock versions during test execution, isolating the code under test. This facilitates the creation of predictable and controlled test environments, enabling focused verification of specific functionalities.

The primary purpose of lenmymock is to provide a flexible and intuitive API for stubbing and restoring modules. It can intercept module loading mechanisms, such as Node.js's require function, and substitute them with custom implementations. This allows testers to simulate various scenarios, including error conditions, specific return values, or modified behavior of external dependencies.

lenmymock supports both synchronous and asynchronous mocking. It offers features to define how dependencies should be mocked, including specifying which modules to mock and what their mocked behavior should be. After the tests are executed, lenmymock also provides mechanisms for restoring the original dependencies, ensuring that tests do not interfere with each other or with subsequent operations. This comprehensive approach contributes to robust and reliable unit testing practices in JavaScript development.
