fake-gateway-rejected-fraud-nonce results in random accepted/failing transaction

Hi braintree-team,

I just stumbled upon a weird issue. When I use fake-gateway-rejected-fraud-nonce for creating a transaction via the following snippet, I sometimes receive an authorized transaction and sometimes the transaction fails as it should, which breaks my tests.

Do you have any clue why this happens?

Thanks a lot! Bastian

return new Promise( (resolve, reject) => {
gateway.transaction.sale({
      amount: 25.14,
      paymentMethodNonce: 'fake-gateway-rejected-fraud-nonce',
      options: { submitForSettlement: false }
    }, (err, res) => {
      if (err) {
        log.error(`Could not create transaction via braintree.`, {paymentMethodNonce, amount, options});
        reject(err);
      } else {
        log.debug(`Payment transation via braintree successful.`, res);
        resolve(res);
      }
    })
  })
}

I am, but I won’t be using braintree again. My tests break every now and then but that’s not a concern really.

The reason for the Gateway rejection when using the fake-gateway-rejected-fraud-nonce is different than when using the amount 5001.00, as one is to replicate a rejection due to fraud rules, and the other an edge case with application status.

There is no need to use both to generate a Gateway rejected transaction, however the fake-gateway-rejected-fraud-nonce will not reject as expected, unless you have fraud tools enabled on your account.
