weltest v0.1.0

Weltest

Library to test welgo library code.

API

Shallow rendering:

const { createElement } = require('welgo');
const htm = require('htm');
const { shallow } = require('weltest');

const html = htm.bind(createElement);

test('<MyComponent /> renders three <Foo /> components', () => {
  const wrapper = shallow(html`<${MyComponent} />`);
  expect(wrapper.find(Foo)).to.have.lengthOf(3);
});

it('<MyComponent /> renders an `.icon-star`', () => {
  const wrapper = shallow(html`<${MyComponent} />`);
  expect(wrapper.find('.icon-star')).to.have.lengthOf(1);
});

Instead of using shallow, you can use mount method:

const { mount } = require('weltest');

The idea of shallow/full-rendering is taken from enzyme.

Right now wrapper offers only one method – find. If you pass a selector (for querySelector), it will return a list of DOM nodes. If you pass an actual component, it will return an array of wrappers, on which you can find again.
