Dealing with   on unit testing

Sometimes we need to use   in our HTML as opposed to a space. However because   has a different byte code, the comparison between   and a space will always return false. That’s why if we want to do assertion with an HTML text containing   characters, we need to replace spaces with \u00a0 (  will be transformed to unix code when rendered).

const mount = function render() {
  return <p>&nbsp;</p>;
};

const wrapper = mount();

expect(wrapper.text()).toBe(" "); // false
expect(wrapper.text()).toBe("\u00a0"); // true
