jest-leak-detector

Module for verifying whether an object has been garbage collected or not.

Internally creates a weak reference to the object, and forces garbage collection to happen. If the reference is gone, it meant no one else was pointing to the object.

Example

```javascript let reference = {};

const detector = new LeakDetector(reference);

// Reference is held in memory. console.log(detector.isLeaking()); // true

// We destroy the only reference to the object. reference = null;

// Reference is gone. console.log(detector.isLeaking()); // false ```
