Parsing error using Jest with Sails.js

I am trying to set up some unit tests using Jest for a new project using sails.js

Unfortunately Jest appears to be scanning and parsing into the node_modules directory of the sails project, where it gets a parse error on a package.json file. This file is not actually a valid package.json file, it is a template from which sails project's package.json files are generated.

Is this a bug that needs to be fixed in Jest, or can I use a configuration option to get it to ignore this file/directory?

Reproduction instructions:

npm install -g sails jest-cli
sails new jesttest
cd jesttest
npm install
jest

Error message:

Using Jest CLI v0.2.1
Error parsing `c:\work\jesttest\node_modules\sails\node_modules\sails-generate\node_modules\sails-generate-adapter\templates\boilerplate\package.json`!

Deeper explanation if anyone's interested: the "package.json" inside of that adapter generator is not a package.json, but an ejs template for one. sails has a lot of those, so if you use more than one add-on, you'll have to keep adding things to that list. sidenote, you won't have this problem if you have your client code in a separate project (repo).

It turned out to be fairly easy - for anyone else who has the same problem just add the following to your package.json file:

"scripts": {
  "start": "node app.js",
  "debug": "node debug app.js",
  "test": "jest"
},
"jest": {
  "modulePathIgnorePatterns": ["sails-generate-adapter"]
}
