Hmm, I'm not familiar with CI at all, but now this PR seems to break tests:

$ python setup.py test
usage: setup.py [global_opts] cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]
   or: setup.py --help [cmd1 cmd2 ...]
   or: setup.py --help-commands
   or: setup.py cmd --help

error: invalid command 'pytest'

I have pytest installed. It also signals an error when run in the project dir:

$ pytest
usage: pytest [options] [file_or_dir] [file_or_dir] [...]
pytest: error: unrecognized arguments: --cov=monero
  inifile: /home/emes/devel/monero-python/setup.cfg
  rootdir: /home/emes/devel/monero-python

why this?

[rooterkyberian]

so pytest will run all test_* methods assuming they are, well, tests.
This is of course a problem for test classes mixins. But then again, you are right in worrying about it as I clearly forgot to reenable it on subclasses.
Fixed in next commit.

I should have both included some instructions in the readme (this is fixed now) from the beginning and description in the pull request explaining what have been done.

So this ticket introduces configuration for Travis CI, which uses pytest runner and Coveralls for showing both if tests are passing and the test coverage.
To enable it you will need to log in with github to both Travis CI http://travis-ci.org/ and Coveralls https://coveralls.io/ and active them for this project. After that and merging this PR tests will automatically start running for every new change commited and every new PR created - which makes reviewing contributions significantly easier. This services are de facto standard (and of course free) for open source projects hosted on github.

Now as to why replaced standard python unittest test runner with pytest. pytest is a very popular test runner for which you will have an easy time to find advantages over unittest module, and in this case, it was just that much easier to integrate test coverage analysis using it.

Sounds great, but still running pytest fails with unrecognized arguments: --cov=monero.

Got the same result in Python 2.7.15 and 3.6.5

and you are sure you have run pip install -r requirements.txt -r test_requirements.txt ?

I had some syntax still messed up in readme, now it should properly render: https://github.com/rooterkyberian/monero-python/blob/ci/README.rst
