Hello,
For 1/ Not sure I follow your question, but this is what you need to do:
1. Clone the killbill master repo
2. Navigate to the killbill directory
3. Run mvn clean install -DskipTests - This will generate the war file in killbill/profiles/killbill/target directory.
For 2/ - Yes, that sounds right. There were some test modifications as part of the fix for 169. See
this commit. Feel free to take a look at the tests to understand what's changed and how you can go about with the testing.
Regards,
Reshma
