class CoolComponent extends React.Component {
    render() {
        return (
            <ul className="cool-list">
                <li className="cool-list-item">1</li>
                <li className="cool-list-item">2</li>
            </ul>
        );
    }

    getNum() {
        return someLib.getNum();
    }
}

export default CoolComponent;

tests/CoolComponent-test.js:

import Mingus from 'mingus';
import someLib from 'someLib';

import CoolComponent from './CoolComponent';


Mingus.createTestCase({
    beforeEach() {
        this.rendered = this.renderComponent(CoolComponent);
        this.component = this.createComponent(CoolComponent);
    },

    testType() {
        this.assertIsType(this.rendered, 'ul')
    },

    testClass() {
        this.assertHasClass(this.rendered, 'cool-list');
    },

    testChildrenClasses() {
        this.assertEveryChildHasClass(this.rendered, 'cool-list-item');
        this.assertSomeChildHasClass(this.rendered, 'cool-list-item');
    },

    testChildrenTypes() {
        this.assertEveryChildIsType(this.rendered, 'li');
        this.assertSomeChildIsType(this.rendered, 'li');
    },

    testNthChildClass() {
        this.assertNthChildHasClass(this.rendered, 0, 'cool-list-item');
    },

    testNthChildType() {
        this.assertNthChildIsType(this.rendered, 0, 'li');
    },

    testGetNum() {
        this.stub(someLib, 'getNum', () => 777);
        this.assertEqual(component.getNum(), 777);
    }
});
