How to use the ts-jest/presets.defaults function in ts-jest

test('presets', () => {
  const presetKeys = ['transform']
  expect(Object.keys(presets.defaults)).toEqual(presetKeys)
  expect(presets.defaults).toEqual(require('ts-jest/presets/default/jest-preset'))
  expect(presets.defaults).toEqual(require('ts-jest/jest-preset'))
  expect(Object.keys(presets.jsWithTs)).toEqual(presetKeys)
  expect(presets.jsWithTs).toEqual(require('ts-jest/presets/js-with-ts/jest-preset'))
  expect(Object.keys(presets.jsWithBabel)).toEqual(presetKeys)
  expect(presets.jsWithBabel).toEqual(require('ts-jest/presets/js-with-babel/jest-preset'))
})

const cfg = {}

  Object.assign(cfg, require('ts-jest/presets').defaults)
} else {
  cfg.preset = 'ts-jest'
}

module.exports = Object.assign({}, cfg, {

const presets = require('ts-jest/presets')
