Stencil Test Helpers

This code is a port from the great ember-test-helpers to be used in Stencil projects.

Getting Started

npm install stencil-test-helpers

So helpers know how to do their thing, the TestWindow class provided by this package needs to be used. It behaves as the normal TestWindow, but with a couple of extra magic bits that let the helpers use their magic.

You need to add a removeTestWindow call in the aferEach hook.

The basic scaffold is:

import { TestWindow, removeTestWindow } from 'stencil-test-helpers';

describe('something', () => {
  afterEach(() => {
    removeTestWindow();
  });
});

Helpers

All the helpers accept a target both as a string (CSS selector) or an Element. All helpers will wait until the next tick before and after doing its work.

The available helpers are:

• blur(target)
• click(target)
• doubleClick(target)
• fillIn(target, value: string)
• focus(target)
• getElement(target): Element | null
• tap(target, options)
• triggerEvent(target, event, options)
• triggerKeyEvent(target, keyEventType, keyOrKeyCode, modifiers)
