Unit testing: react context api with enzyme return an empty object

Question

I am trying for the first time to use React context API to pass information from a main component to his grandchild component.

So first I have created a context

Answer 1

Enzyme context affects legacy React context, not modern context API. It should be mocked with:

mount()

And asserted with:

expect(wrapper.find('h2').text()).toBe('Context value: 987');
