• Any custom typing files or files which are needed to be compiled and intended to use with jest need to be defined in files option of tsconfig.

For example:

// tsconfig.json
{
   // ...other configs
   "files": [
       "my-custom-typings.d.ts",
       "my-global-module.ts"
   ]
}

• compiler: incremental and compilerHost options are no longer available. Please remove it from your ts-jest config.
