    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

    (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
    })();
