Use individual helper functions

In addition to the toJson helper that is recommended you can use individual helpers for each type of Enzyme wrapper.

You can pass an options object to them, just like you do with the toJson helper.

shallowToJson

import {shallowToJson} from 'enzyme-to-json';

// or

import shallowToJson from 'enzyme-to-json/shallow';

it('converts shallow wrappers', () => {
  const wrapper = shallow(<div>Hello</div>);
  expect(shallowToJson(wrapper)).toMatchSnapshot();
});

mountToJson

import {mountToJson} from 'enzyme-to-json';

// or

import mountToJson from 'enzyme-to-json/mount';

it('converts mount wrappers', () => {
  const wrapper = mount(<div>Hello</div>);
  expect(mountToJson(wrapper)).toMatchSnapshot();
});

renderToJson

import {renderToJson} from 'enzyme-to-json';

// or

import renderToJson from 'enzyme-to-json/render';

it('converts render wrappers', () => {
  const wrapper = render(<div>Hello</div>);
  expect(renderToJson(wrapper)).toMatchSnapshot();
});
