What's wrong with importing a library?

Question

Unit testing

I'm trying to import https://testing-library.com/
Importing screen into the test file

jest-setup.ts

jest.config.js

if you write "include": ["./jest-setup.ts","], then the library is imported

But when you use alias it writes this

"include": ["./jest-setup.ts", "src/"]. But when so then the library is not found again
