// jest.config.js
module.exports = {
   //...
   globals: {
      'ts-jest': {
         astTransformers: {
           before: ['your_before_transformer_path'],
           after: ['your_after_transformer_path'],
           afterDeclarations: ['your_afterDeclarations_transformer_path'],
         }
      }
   }
}

or

// package.json
{
  "jest": {
     "globals": {
        "ts-jest": {
           "astTransformers": {
              "before": ["your_before_transformer_path"],
              "after": ["your_after_transformer_path"],
              "afterDeclarations": ["your_afterDeclarations_transformer_path"]
           }
        }
     }
  }
}

• One currently refers type in jest.config.js

/** @typedef {import('ts-jest')} */
module.exports = {
  //...
}

should change to

/** @typedef {import('ts-jest/dist/types')} */
module.exports = {
  //...
}

• Remove possibilities to import mocked, createJestPreset, pathsToModuleNameMapper from package entry. One should change to

import { mocked, createJestPreset, pathsToModuleNameMapper` } from 'ts-jest/utils'
