BDD

What is needed:

Virtual environment configuration - recommended option

1. Python 3 (e.g. 3.7)

   $ sudo add-apt-repository ppa:deadsnakes/ppa
   $ sudo apt-get update
   $ sudo apt-get install python3.7

2. pip:

   $ sudo apt install python3-pip

3. Virtual environment for Python

   1. Installation

      $ pip3 install virtualenvwrapper

   2. Add to file "~/.bashrc"

      $ echo 'VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3' >> ~/.bashrc
      $ echo 'source `which virtualenvwrapper.sh`' >> ~/.bashrc
      $ source ~/.bashrc 

   3. Create your own virtualenv:

      $ mkvirtualenv qa-has-power -p `which python3.7`

   4. Switch to your virtualenv

      $ workon qa-has-power

4. Requirements:

   1. Behave and Selenium (installation from requirements):

      $ pip install -r requirements.txt

5. Chrome and chromedriver

   $ wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb && dpkg -i google-chrome-stable_current_amd64.deb; apt-get -fy install
   $ wget -O /tmp/chromedriver.zip http://chromedriver.storage.googleapis.com/73.0.3683.68/chromedriver_linux64.zip && sudo unzip /tmp/chromedriver.zip chromedriver -d /usr/local/bin/ && sudo chmod 755 /usr/local/bin/chromedriver;

Docker environment configuration - alternative option

1. Docker installation:

   $ ./install_docker.sh

2. Give access to show windows run in Docker

   $ xhost +local:root

3. Build docker image

   $ docker build -t docker_tag .

4. Run docker image

   $ docker run -it -v $PWD:/usr/src -v /tmp/.X11-unix:/tmp/.X11-unix -e DISPLAY=$DISPLAY -t docker_tag bash

Test:

1. Run test file to check if your environment is ready to use:
   1. For virtualenv - with virtualenv switched on

      $ python ./check.py

   2. For Docker - inside the docker container (after command $ docker run...) :

      $ python check.py 

Usage:

1. Run tests:

   $ behave

2. To debug during implementation - you can use ipdb,
   1. Put this lines before line with error:

      import ipdb 
      ipdb.set_trace()

   2. Run tests with parameter:

      $ behave --no-capture

   3. Tests should stop in correct place, there should be possible to n
