.props() => Object

Returns the props object for the root node of the wrapper. It must be a single-node wrapper.

This method is a reliable way of accessing the props of a node; wrapper.instance().props will work as well, but in React 16+, stateless functional components do not have an instance. See .instance() => ReactComponent


import PropTypes from 'prop-types';

function MyComponent(props) {
  const { includedProp } = props;
  return (
    <div className="foo bar" includedProp={includedProp}>Hello</div>
MyComponent.propTypes = {
  includedProp: PropTypes.string.isRequired,

const wrapper = mount(<MyComponent includedProp="Success!" excludedProp="I'm not included" />);

// Warning: .props() only returns props that are passed to the root node,
// which does not include excludedProp in this example.
// See the note above about wrapper.instance().props.

// {children: "Hello", className: "foo bar", includedProp="Success!"}

console.log(wrapper.instance().props); // React 15.x - working as expected
// {children: "Hello", className: "foo bar", includedProp:"Success!", excludedProp: "I'm not included"}

// React 16.* - Uncaught TypeError: Cannot read property 'props' of null
