Commis (@mise/test)

Commis is a testing suite for Mise that makes it easy to test Mise components. Commis properly sets up your environment to handle components and simplify renders.

We strongly suggest using Commis with Jest.

Installation

npm i --save-dev @mise/test

In your actual project

import { commis } from '@mise/test';

Example

import { dom, component } from '@mise/core';
import { commis } from '@mise/test';

import { template, state, actions, middleware } from './component/index';

const { render } = commis();

describe('component test', () => {
  beforeEach(async () => {
    component({
      template,
      state,
      actions,
      middleware, 
    });

    await render();
  });

  it('should render a div', () => {
    expect(document.querySelectorAll('div').length).toBe(1);
  });

  it('should render after an action', async () => {
    document.querySelector('button').click();

    /* optionally, render takes in a millisecond parameter to wait for a render to occur */
    await render(100);
    expect(document.querySelector('span').textContent).toEqual('success');
  });
})
