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')); }) })
