.invoke(propName)(...args) => Any

Invokes a function prop. Note that in React 16.8+, .invoke will wrap your handler with ReactTestUtils.act and call .update() automatically.

Arguments

1. propName (String): The function prop that is invoked
2. ...args (Any [optional]): Arguments that is passed to the prop function

Returns

Any: Returns the value from the prop function

Example

class Foo extends React.Component {
  loadData() {
    return fetch();
  }

  render() {
    return (
      <div>
        <button
          type="button"
          onClick={() => this.loadData()}
        >
          Load more
        </button>
      </div>
    );
  }
}
const wrapper = mount(<Foo />);
wrapper.find('button').invoke('onClick')().then(() => {
  // expect()
});
