config object from ts-jest/presets is missing testMatch and moduleFileExtensions params

[vbvxx]

Issue:

After bumping to 24.0.2, when I import the defaults presets from 'ts-jest/presets'

const { defaults: tsjPreset } = require("ts-jest/presets");

I get the following config object:

{ transform: { '^.+\\.tsx?$': 'ts-jest' } }

Expected behavior:

I would expect the output I had when using 23.10.4:

{ 
  transform: { '^.+\\.tsx?$': 'ts-jest' },
  testMatch:
   [ '**/__tests__/**/*.[jt]s?(x)',
     '**/?(*.)+(spec|test).[tj]s?(x)',
     '**/__tests__/**/*.ts?(x)',
     '**/?(*.)+(spec|test).ts?(x)' ],
  moduleFileExtensions: [ 'js', 'json', 'jsx', 'ts', 'tsx', 'node' ] 
}

Debug log:

log file content

# content of ts-jest.log :
# it was empty

This is a dump project where I just console print the defaults from ts-jest/presets in jest.config.js, where we can see that there is only transform defined when running yarn jest

This is expected change in v24 due to #957, including the discussion to simplify this preset.
