Struggling with TypeScript tests elusive to Jest

I'm encountering a strange error while attempting to write a jest test. 

TypeError: jest_1.it is not a function

   9 |
  10 | describe('Health check', () => {
> 11 |     it('GET works', async () => {

Instead of displaying all the different configuration files, I'll focus on the specific components being used: serverless framework with serverless-plugin-typescript plugin, typescript, jest, ts-jest.

My understanding is that ts-jest should handle TS compilation and hand it over to Jest. However, since serverless has its own opinionated TS configuration, it might be conflicting with ts-jest.

Any suggestions on what I should investigate further?

Edit: code block formatting adjustment

Answer №1

Finally cracked the code. I mistakenly imported it at the beginning of my testing file:

import {it} from 'jest'

After removing it, everything fell into place. Now, it's time to delve deeper into modules.
