How to test a Plone add-on¶
To better understand how to test a Plone add-on, the best thing is to create a new Plone package from scratch and use it to see different testing techniques.
We are going to use the plonecli tool heavily because it lets you create new Plone packages and related features such as content types, views, and vocabularies, all using simple commands.
First, we need to install plonecli:
$ pip install plonecli --user
This command will install plonecli in the user site-packages according to the official documentation. Feel free to install it using your preferred alternative method (virtualenv, pipenv, pyenv).
If you have already installed plonecli, please update at least bobtemplates.plone to the most recent version (>= 5.0.1) because there are some important fixes needed for this training.
Now we can create a new package:
$ plonecli create addon plonetraining.testing
$ cd plonetraining.testing $ plonecli build
This command will create a virtualenv, install dependencies and run buildout.
Let’s run some tests! plonecli provides some default tests when creating a new package:
$ plonecli test
Let’s run all tests, including robot tests (we will cover these later):
$ plonecli test --all
If you get an error about missing
geckodriver, you will have to install
On macOS, you can use
brew install geckodriver.
On Ubuntu, you can use
apt install firefox-geckodriver.
plonecli test --all.
