UI Testing with Enzyme

  Pros
- Very easy to set up for unit testing regardless of what other testing tools are used
- Does not require a special environment and configuration
- Good documentation and simple API
- Very fast
- Provides facilities for testing the instance of the component directly:
describe('Tags multiselect', () => {
it('should pass correct data options to the Multiselect component', () => {
const tags = [
{ id: '1', label: 'B' },
{ id: '2', label: 'A' },
];

const wrapper = mount(
<Tags
{...baseProps}
tags={tags}
/>
);

const propsPassedToMultselection = wrapper.find(MultiSelection).props();

expect(propsPassedToMultselection.dataOptions).to.deep.equal([
{ value: 'a', label: 'a' },
{ value: 'b', label: 'b' },
]);
});
});

Cons
- Issues with testing hooks
- Provides facilities for testing the instance of the component directly. This can encourage harmful testing approaches.
- React testing library
