Returns whether or not the current wrapper root node render tree looks like the one passed in.
node(ReactElement): The node whose presence you are detecting in the current instance's render tree.
Boolean: whether or not the current wrapper has a node anywhere in it's render tree that looks
like the one passed in.
const wrapper = shallow(<MyComponent />);
expect(wrapper.equals(<div className="foo bar" />)).to.equal(true);.equals()expects a ReactElement, not a selector (like many other methods). Make sure that when you are calling it you are calling it with a ReactElement or a JSX expression.- Keep in mind that this method determines equality based on the equality of the node's children as well.
