# 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
|
|
```
