Development process

Developers work in their own trees, then submit pull requests when they think their feature or bug fix is ready.

If it is a simple/trivial/non-controversial change, then one of the zcoin development team members simply pulls it.

If it is a more complicated or potentially controversial change, then the patch submitter will be asked to start a discussion (if they haven't already) on the Slack : ZCoin General Channel. You can get invite from here

The patch will be accepted if there is broad consensus that it is a good thing. Developers should expect to rework and resubmit patches if the code doesn't match the project's coding conventions (see doc/coding.txt) or are controversial.

The master branch is regularly built and tested, but is not guaranteed to be completely stable. Tags are created regularly to indicate new official, stable release versions of ZCoin.


Automated Testing

Developers are strongly encouraged to write unit tests for new code, and to submit new unit tests for old code.

Unit tests for the core code are in src/test/. To compile and run them:

cd src; make -f makefile.unix test

Unit tests for the GUI code are in src/qt/test/. To compile and run them:

qmake BITCOIN_QT_TEST=1 -o Makefile.test
make -f Makefile.test
