Unit testing typescript SPFx web part using jest

[rahil1998]

Question:

How do you unit test the SPFx web part, written in typescript (react), that uses @pnp Call to communicate with SharePoint?
How to mock PNP call or how to make ignorable for the test case.

below I mentions the error related to PNP

E:\Projects\Unit Testing\SPFx-unit-testing\node_modules\@pnp\logging\index.js:1
    ({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,jest){export * from "./logger";
                                                                                      ^^^^^^

    SyntaxError: Unexpected token export

      3 | import { IPnpSpCrudProps } from './IPnpSpCrudProps';
      4 | import { escape } from '@microsoft/sp-lodash-subset';
    > 5 | require("@pnp/logging");
        | ^
      6 | require("@pnp/common");
      7 | require("@pnp/odata");
      8 | import { sp } from "@pnp/sp/presets/all";

I have configured the unit test and sample test execute successfully (without PNP)
