# 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 |
|
(async function () { |
|
let reference = {}; |
|
let isLeaking; |
|
|
|
const detector = new LeakDetector(reference); |
|
|
|
// Reference is held in memory. |
|
isLeaking = await detector.isLeaking(); |
|
console.log(isLeaking); // true |
|
|
|
// We destroy the only reference to the object. |
|
reference = null; |
|
|
|
// Reference is gone. |
|
isLeaking = await detector.isLeaking(); |
|
console.log(isLeaking); // false |
|
})(); |
|
```
