// The purpose of this class is to provide testing facility for the
// SerializerForBackgroundCompilation class. On a high-level, it executes the
// following steps:
// 1. Wraps the provided source in an IIFE
// 2. Generates bytecode for the given source
// 3. Runs the bytecode which *must* return a function
// 4. Takes the returned function and optimizes it
// 5. The optimized function is accessible through `function()`
