Demonstration application for the Deform Python HTML form library.
This application is tested on Python versions 3.6, 3.7, 3.8, and 3.9, and PyPy3.
Build the Docker image for deformdemo and tag it.
# docker build --tag pylons/deformdemo3:<version> . docker build --tag pylons/deformdemo3:main .
Run the built image with Docker.
docker run -d -p 8000:8523 pylons/deformdemo3:main
Then in your browser, visit http://localhost:8000
To stop the docker container, find its
NAME and issue the
docker ps -a docker stop <value_from_NAMES_column>
Create a virtual environment.
python3 -m venv /path/to/my/env
/path/to/my/envwill be referred to as
$VENVin the following steps.
git clone git://github.com/Pylons/deformdemo.git
cdto the newly checked out deformdemo package.
pip install -e .using the virtual environment's
$VENV/bin/pip install -e .
While your working directory is still
deformdemo, start the demo application.
Visit http://localhost:8523 in a browser to see the demo.
Install functional test requirements
deformdemo application serves as a target for functional testing during Deform's development.
A suite of Selenium tests may be run against a local instance of the demonstration application.
It is wise to run these tests using the following steps before submitting a pull request.
First prepare the functional test environment by installing requirements. We will assume that you put your projects in your user directory, although you can put them anywhere.
Install Python development and testing requirements
The following command will install requirements for development and testing of deformdemo.
It performs editable installs of Colander and Deform into your virtual environment's
src directory, and deformdemo's testing requirements into
$VENV/bin/pip install -Ur requirements-dev.txt
Install Firefox latest
.dmg (macOS), and drag the Firefox icon to:
Use cURL or wget. See the Firefox download README.txt for instructions. For example on Linux:
cd ~/projects/deformdemo/ wget -O firefox-latest.tar.bz2 \ "https://download.mozilla.org/?product=firefox-latest&os=linux64&lang=en-US"
Decompress the downloaded file.
tar -xjf firefox-latest.tar.bz2
Install the latest release of geckodriver.
# macOS wget https://github.com/mozilla/geckodriver/releases/download/v0.29.0/geckodriver-v0.29.0-macos.tar.gz tar -xzf geckodriver-v0.29.0-macos.tar.gz # Linux (Debian) wget https://github.com/mozilla/geckodriver/releases/download/v0.29.0/geckodriver-v0.29.0-linux64.tar.gz tar -xzf geckodriver-v0.29.0-linux64.tar.gz
The functional tests require the installation of the GNU
gettext utilities, specifically
Use your package manager to install these requirements.
brew install gettext brew link gettext --force
If you ever have problems building packages, you can always unlink it.
brew unlink gettext
apt-get install gettext apt-get install gettext-base
Selenium was already installed via
$VENV/bin/pip install -Ur requirements-dev.txt.
Running the Demo's Functional Tests
deformdemoapplication as described above in "Running the Demo". Leave the terminal window running this application open, and open a second terminal window to perform the below steps.
In the second terminal window, go to the "deformdemo" checkout directory you created above in "Running the Demo".
Set an environment variable to add your local checkout of Deform to your
PATH. It must to be set before running tox or pytest, otherwise Firefox or Chrome will not start and will return an error message such as
'geckodriver' executable needs to be in PATH.
Run the tests.
$VENVis defined as it was in "Running the Demo" above.
You will (hopefully) see Firefox pop up and it will begin to display in quick succession the loading of pages. The tests will run for five or ten minutes.
Test success means that the console window on which you ran
pytestshows a bunch of dots, a test summary, then
OK. If it shows a traceback,
FAILED, or anything other than a straight line of dots, it means there was an error.
Fix any errors by modifying your code or by modifying the tests to expect the changes you've made.
Testing an Alternate Renderer Implementation
- Copy the
demo.inifile from this demo package to your renderer's package.
- Change the
deform.rendererkey in the
demo.inicopy to point at your renderer (it's a Python dotted name).
- Run the Selenium tests as above.
