| # 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.isLeaked()); // true
 | |
| 
 | |
| // We destroy the only reference to the object.
 | |
| reference = null;
 | |
| 
 | |
| // Reference is gone.
 | |
| console.log(detector.isLeaked()); // false
 | |
| ```
