javascript - How to test child component method with Enzyme?

Question

I have a component like that:

<Parent>
  <Child/>
</Parent>

and <Child/> component have a method foo. I want test the foo method but I don't know how to access it. I tried:

mount(<Parent><Child/></Parent>).props().children.foo

or

mount(<Parent><Child/></Parent>).children().foo

but both them are undefined. I can't use .instance() because it's not root. I can't mount <Child/> only because the <Parent> add something (react-router's context.router) on context and I need them when init <Child/>. Any idea with this?

Answer 1

This worked for me:

mount(<Parent><Child/></Parent>).find(Child).instance().foo
