Hi, i’m facing a small issue which doesn’t affect the web application at all. but thought of leave it on the issues for just in case. Please let me know if more info is needed. Thanks.

By mock the Braintree calls, I meant, mock the methods.

Example using sinon:

var sinon = require('sinon');
var fakeClient = {};
var fakeHostedFields = {
  tokenize: sinon.stub().yields(null, {nonce: 'a-nonce'})
};

sinon.stub(braintree.client, 'create').yields(null, fakeClient);
sinon.stub(braintree.hostedFields, 'create').yields(null, fakeHostedFields);

We’ve switched over from global -> window in v3.63.0, which should take care of your issue @saraedum
