`jest-mock-process` is a utility library that simplifies mocking NodeJS process properties in Jest tests, providing functions to mock process exit, stdout, stderr, uptime, and console log. It's designed for developers writing unit tests in Node.js applications who need to isolate and test code that interacts with process-level functionality without affecting the actual process. The library supports both basic mocking and advanced usage with automatic mock restoration, making it particularly useful for testing CLI tools, server processes, and any Node.js code that relies on process properties.
