CodePudding user response：

You have to update your import to:

import { MockedProvider } from '@apollo/client/testing';

From the Apollo Client 3.0 migration doc:

react-apollo v3 is an umbrella package that re-exports the following packages:

@apollo/react-common

@apollo/react-hooks

@apollo/react-components

@apollo/react-hoc

@apollo/react-ssr

@apollo/react-testing

The react-apollo package has been deprecated, and the functionality offered by each of the above packages can now be accessed from @apollo/client directly:

@apollo/react-hooks -> now available directly from @apollo/client

@apollo/react-components -> now available from @apollo/client/react/components

@apollo/react-hoc -> now available from @apollo/client/react/hoc

@apollo/react-ssr -> now available from @apollo/client/react/ssr

@apollo/react-testing -> now available from @apollo/client/testing
