type script reference path is not getting resolved in jest

[pallabrath]

In one of the ts file (query_ctrl.ts) the module import are like below

///

import { QueryCtrl } from 'app/plugins/sdk';
export class MyQueryCtrl extends QueryCtrl
{ .....

In module.ts
export {
MyQueryCtrl as QueryCtrl
};
While in jest test module.test.ts
import { QueryCtrl } from '../../datasource/module'

● Test suite failed to run

Cannot find module 'app/plugins/sdk' from 'query_ctrl.ts'

Require stack:
  src/datasource/query_ctrl.ts
  src/datasource/module.ts
  src/specs/datasource/module.test.ts


   6 | import { Utils } from './Utils';

jest.config.js

module.exports = {
preset: 'ts-jest',
testEnvironment: 'node',
coverageDirectory: "work/coverage",
};

Yeah, Jest doesn't support that, and we won't - starting to deal with how bundlers and type checkers do resolution is out of scope for us. You need to use moduleNameMapper. This might be something ts-jest could do automatically, though? Not sure - might be worth an issue over there.

Thanks, I had tried moduleNameMapper, not much luck. Any way will try with ts-js. Lets see
