ReactTestRenderer: Invariant Violation: getNodeFromInstance: Invalid argument.

[rhalff]

I'm following the example at https://facebook.github.io/jest/docs/tutorial-react.html#content in order to use snapshots with jest.

I run into a bug within react-test-renderer, it seems to fail whenever findDOMNode is used on a component instance.

Minimal code to replicate the bug:

import React, { Component } from 'react'
import { findDOMNode } from 'react-dom'
import renderer from 'react-test-renderer'

class MyComp extends Component {
  componentDidMount() {
    findDOMNode(this)
  }
  render() {
    return <i />
  }
}

renderer.create(<MyComp />);

The Error:

 Invariant Violation: getNodeFromInstance: Invalid argument.

Nevermind, just found it's not supported: #7371

Yea sorry, refs can work but findDOMNode() can't (we tried).

[scrodrig]

I also have a problem....
When send a function in a prop to a child component... The production code works, however the test doesn't work same error. :(

[gaearon]

If you mean you're using findDOMNode() in test renderer, it won't work.
Please see #7371 for reasons why.

I came upon this issue after upgrading from Enzyme 2 to Enzyme 3. If anyone experiences this when upgrading Enzyme, it can be fixed by disabling testing of the lifecycle methods:

configure({
  adapter: new Adapter(),
  disableLifecycleMethods: true,
})
