    Usage

    To use it, import the module, and pass it a function. A promise is returned, and it is resolved after the passed function returns a truthy value. If the function passed never returns a truthy value, or it times out, the promise is rejected.

    import $ from 'jquery';
    import waitUntil from 'wait-until-promise';
     
    describe('some thing', () => {
      it('should do something', (done) => {
        const button = $('#button');
        const paragraph = $('p');
     
        button.click();
     
        waitUntil(() => paragraph.text() === 'button clicked')
          .then(() => done());
      })
     
      // The promise is resolved with the return-value. Useful to if you want to
      // wait until something exists, then make assertions on it
      it('should do something else', (done) => {
        const button = $('#button');
        const paragraph = $('p');
     
        button.click();
     
        waitUntil(() => paragraph.text())
          .then((text) => expect(test).toBe('The text in the paragraph'));
      })
    })
