Testing

Installation

$ npm install @slicky/tester

Usage

Package @slicky/tester contains simple utility class for bootstrapping new applications in virtual dom.

It uses the jsdom package so you don't need to configure headless chrome nor phantom js.

import 'zone.js';
import 'reflect-metadata';

import {Tester, ApplicationRef} from '@slicky/tester';
import {Component} from '@slicky/core';
import {expect} from 'chai';

@Component({
	name: 'test-component',
	template: '{{ message }}',
})
class TestComponent
{

	public message = 'Hello world';

}

const app = Tester.run('<test-component></test-component>', {
	directives: [TestComponent],
});

expect(app).to.be.an.instanceOf(ApplicationRef);
expect(app.document.body.textContent).to.be.equal('Hello world');

You can use any assertion library you want.
