From a2a923fa9994c7d6069f48c7be9733c77bd0ce7d Mon Sep 17 00:00:00 2001 From: MattFaus Date: Sun, 9 Mar 2014 19:49:39 -0700 Subject: [PATCH 01/13] Get Transaction test cases running I removed the skip over the tx_valid.json file and made some tweaks to get most of the test cases passing. There are still two test cases that fail, as pointed out by the TODO comment I added above them. Oddly, running the test suite reports 3 failing test cases, but if I delete the two marked with the TODO there are 0 reported failures. So, there may be some kind of interaction with these test cases and the others. More investigation is needed. I updated the two test cases that were testing transaction `23b397edccd3740a74adb603c9756370fafcde9bcc4483eb271ecad09a94dd63` with the input script I found on blockchain.info https://blockchain.info/tx/23b397edccd3740a74adb603c9756370fafcde9bcc4483eb271ecad09a94dd63. A quick search found one other person who was using this same script (https://github.com/lian/bitcoin-ruby/blob/master/spec/bitcoin/fixtures/23b397edccd3740a74adb603c9756370fafcde9bcc4483eb271ecad09a94dd63.json) and the test passes now, so I'm not sure why the old script was being used. All of the other changes are simply re-formatting decimal numbers as hex (i.e. `1` => `0x01`). Furthermore, I added some code in the test fixture itself to verify each of the inputs.
