Check if child component rendered – Jest, Enzyme

You can check whether a parent component has rendered its child component using containsMatchingElement().

Based on Enzyme docs:

Returns whether or not a patternNode react element matches any element in the render tree.

Your test should look like this:

describe('Parent Component', () => {
  it('renders Child component', () => {
    const wrapper = shallow(<Parent store={store} />);
    expect(wrapper.containsMatchingElement(<Child />)).toEqual(true);
  });
});
