How to run behave

The default behave driver is at the moment set to firefox. This can be reset by the environment variable DRIVER. It is coded within features/environment.py.

Firefox

For using Firefox you must install the Firefox Geckodriver from Github and place it in the virtualenv bin directory

version=$(curl -sX GET https://api.github.com/repos/mozilla/geckodriver/releases/latest | grep 'tag_name' | cut -d\" -f4)
wget "https://github.com/mozilla/geckodriver/releases/download/${version}/geckodriver-${version}-macos.tar.gz" -O - | tar xz
mv geckodriver ./bin/

Chrome

To enable the chrome automation you must install the Chromedriver from Google and place it in the virtualenv bin directory.

curl -O "https://chromedriver.storage.googleapis.com/83.0.4103.39/chromedriver_mac64.zip"
unzip chromdriver_mac64.zip
mv chromedriver ./bin/

To switch behave to chrome you just need to set DRIVER variable

DRIVER=chrome ./bin/behave

Headless

Headless testing on your local machine just requires docker installed. You can start the container by following commandline

docker run -d -p 4444:4444 -e START_XVFB=false --shm-size 2g --name chrome-selenium selenium/standalone-chrome

The default configuration of chrome headless will point to the default selenium hub api. But this can also be reset by an environment variable SELENIUM

To run the selenium tests use following command

DRIVER=headless ./bin/behave

TODO

At the moment headless testing is broken for about_page feature. This tests always returns a Connection refused error.
