The issue reports that Enzyme's shallow rendering does not cover React.lazy components, reducing code coverage. Refer to the linked comment in issue #1917 for context. Investigate the shallow rendering adapter for React 16 (packages/enzyme adapter react 16) and identify where React.lazy should be handled. Write a test to ensure the lazy loaded component is recognized and covered.
