Cannot figure out how to mock ES6 modules for a Node AWS Lambda
ESM modules need custom loaders for mocking. Testsouble (https://www.npmjs.com/package/testdouble) was one of the first frameworks to support it AFAIK and a great type-safe option.

TypeScript testing
Alternative is using testdouble with `td.object()` https://www.npmjs.com/package/testdouble

Testing Without Mocks
I’m not sure I manage to follow the author correctly, but to me it seems that by “mock” they strictly refer to external mocking libraries, in the sense of JS’s `testdouble` [1] or Java’s `Mockito` [2]. The fake object as returned by `LoginClient.createNull().getUserInfo(...)` appears to be a “Nullable” for them.
