The article explores the concept of 'self-calling executables' where a program launches another instance of itself, primarily for testing purposes in Go. It demonstrates how this technique can help isolate tests and handle global state issues by running the main executable as a subprocess with specific environment variables. The approach is also useful for interacting with command-line tools like SSH that require external executables for user input.
Background
In software development, testing complex applications often requires creative solutions to handle global state and isolation. The Go programming language provides specific testing mechanisms that developers can leverage for better test architecture.
