How to write a Jest configuration file

Question

I am trying to pass along a configuration file to Jest in order to run tests only from a given directory.

According to documentation, you can use config.testPathDi

The docs were updated to explain the configuration. Here is the link for anyone looking for more information:

The gist:

If using the --config to direct jest to your configuration json file, you only put the JSON information in the file without the "jest" keyword.

// config.json at 
{
   "verbose": true
}

If you want to use the package.json to configure jest, add the "jest" key and then your configuration.

// package.json 
{ 
   "name": "packageName",
   "version": "1.0.0",
   "jest": {
     "verbose": true
   }
}
