Running tests

Requirements for running behave tests:

  1. PostgreSQL packages need to be installed.

  2. PostgreSQL binaries must be available in your PATH. You may need to add them to the path with something like PATH=/usr/lib/postgresql/11/bin:$PATH python -m behave.

  3. If you’d like to test with external DCSs (e.g., Etcd, Consul, and Zookeeper) you’ll need the packages installed and respective services running and accepting unencrypted/unprotected connections on localhost and default port. In the case of Etcd or Consul, the behave test suite could start them up if binaries are available in the PATH.

Install dependencies:

# You may want to use Virtualenv or specify pip3.
pip install -r requirements.txt
pip install -r requirements.dev.txt

After you have all dependencies installed, you can run the various test suites:

# You may want to use Virtualenv or specify python3.

# Run flake8 to check syntax and formatting:
python setup.py flake8

# Run the pytest suite in tests/:
python setup.py test

# Run the behave (https://behave.readthedocs.io/en/latest/) test suite in features/;
# modify DCS as desired (raft has no dependencies so is the easiest to start with):
DCS=raft python -m behave
