Isolator Laravel Package

Isolator is a PHP library for isolating static methods and global functions during unit tests, making otherwise untestable code—especially legacy code—fully mockable. It works by loading classes through a custom class loader that rewrites source code at runtime, redirecting calls to functions like time() or rand() toward controllable test doubles.

• Mock built-in functions such as time(), rand(), and file_get_contents()
• Isolate static methods without modifying production code
• Seamless PHPUnit integration via annotations
• Configurable isolation with a simple, expressive API
• No PECL extensions or special runtime requirements
