Same as https://github.com/facebook/react/issues/10103, but for the server renderer. You can look at implementation in https://github.com/facebook/react/pull/11168 and do something very similar in `ReactPartialRenderer.js`.
render() {
          return <span>My name is {this.props.name}</span>;
        }
      }
      const response = ReactDOMServer.renderToString(<Parent />);
      expect(response).toMatch(
        new RegExp(
          '<div ' +
            'data-reactroot' +
            '=""' +
            '>' +
            '<span' +
            '>' +
            'My name is <!-- -->child' +
            '</span>' +
            '</div>',
        ),
      );
    });
    it('should only execute certain lifecycle methods', () => {
      function runTest() {
        const lifecycle = [];
        class TestComponent extends React.Component {
