I believe the comment was misunderstood.

I agree, `beforeEach()` and `afterEach()` are dangerous and should be avoided in favour of a more verbose and isolated method to setup unique state for each test.

personally I opt for the following:

function props(props = {}) {
 const defaultProps = {
 firstName: ‘Bill’,
 lastName: ‘Murray’,
 displayName: () => {},
 };
 
 return merge({}, defaultProps, props);
 }
 
 const element = shallow(<Person {…props({ firstName: ‘Mr Bill’})} />);

Just personally, novice devs never get near our production code. But really this is a silly argument as we have no shared definition of “novice coder”. Mute point.
