If you're looking for the latest version, please check out the successor project: eQ Questionnaire Runner.
Install Docker for your system: https://www.docker.com/
To get eq-survey-runner running the following command will build and run the containers
docker-compose up -d
To launch a survey, navigate to http://localhost:8000/
When the containers are running you are able to access the application as normal, and code changes will be reflected in the running application. However, any new dependencies that are added would require a re-build.
To rebuild the eq-survey-runner container, the following command can be used.
docker-compose build
If you need to rebuild the container from scratch to re-load any dependencies then you can run the following
docker-compose build --no-cache
To run just the unit tests inside Docker:
docker build -t onsdigital/eq-survey-runner .
docker build -t onsdigital/eq-survey-runner-unit-tests -f Dockerfile.test .
docker run onsdigital/eq-survey-runner-unit-tests
To run the unit tests locally:
pipenv run scripts/run_tests_unit.sh
In order to run locally you'll need PostgreSQL, Node.js, sqlite3, snappy and pyenv installed
brew install postgres snappy npm sqlite3 pyenv
Note that npm currently requires Python 2.x for some of the setup steps, it doesn't work with Python 3.
It is preferable to use the version of Python locally that matches that
used on deployment. This project has a .python_version file for this
purpose.
Upgrade pip and install dependencies:
pyenv install
pip install --upgrade pip setuptools pipenv
pipenv install --dev
Run the server inside the virtual env created by Pipenv with:
pipenv run ./scripts/run_app.sh
Note, you will also need to run an upstream tool (eg, https://github.com/ONSDigital/go-launch-a-survey) to launch a survey.
docker run -e SURVEY_RUNNER_SCHEMA_URL=http://docker.for.mac.host.internal:5000 -it -p 8000:8000 onsdigital/go-launch-a-survey:latest
This will generate a JWT for you to log into the application.
To submit data you will also need to run an additional upstream tool (eg, https://github.com/ONSDigital/eq-docker-dynamodb) to launch a dynamoDB container.
docker run -it -p 6060:8000 onsdigital/eq-docker-dynamodb:latest
Please note that currently the SQL backend only supports questionnaire state
The front-end toolkit uses nodejs, yarn and gulp.
Currently, in order to build the front-end toolkit, you will need to have node version 8.X. To do this, do the following commands:
brew install nvm
nvm install 8
nvm use 8
Install yarn with:
npm install yarn --global
Fetch npm dependencies (Note that this overrides the python version defined in .python-version):
PYENV_VERSION=system yarn
Compile the project with
yarn compile
There are a few additional npm tasks:
| Command | Task |
|---|---|
yarn compile |
Build the assets (js, css, img) into /static. |
yarn dev |
Build assets and watch for changes. Runs Browsersync. |
yarn test |
Runs the unit tests through Karma and the functional tests through a local Selenium instance. |
yarn test_unit |
Watches the unit tests via Karma. |
yarn test_functional |
Runs the functional tests through ChimpJS (requires app running on localhost:5000 and generated pages). |
yarn generate_pages |
Generates the functional test pages. |
yarn lint |
Lints the JS, reporting errors/warnings. |
yarn format |
Format the json schemas. |
Upgrade usage of the pattern library (Currently) To make an upgrade to the pattern library you'll need to change the short-hand commit hash in the following files:
- app/assets/favicons/browserconfig.xml
<square150x150logo src="https://cdn.ons.gov.uk/sdc/[COMMIT HASH HERE]/favicons/mstile-150x150.png"/> - app/assets/styles/partials/vars/_vars.scss.xml
$cdn-url-root: "https://cdn.ons.gov.uk/sdc/[COMMIT HASH HERE]"; - app/templates/layouts/base.html
{% set cdn_hash = "[COMMIT HASH HERE]" %}
The functional tests use a set of selectors that are generated from each of the test schemas. These make it quick to add new functional tests.
To run the functional tests use the script:
./scripts/run_tests_functional.sh
This will delete the tests/functional/generated_pages directory and regenerate all the files in it from the schemas.
You can also individually run the generate_pages and test_functional yarn scripts:
yarn generate_pages; yarn test_functional
To generate the pages manually you can run the generate_pages scripts with the schema directory. Run it from the tests/functional directory as follows:
./generate_pages.py ../../data/en/ ./generated_pages -r "../../base_pages"
To generate a spec file with the imports included, you can use the generate_pages.py script on a single schema with the -s argument.
./generate_pages.py ../../data/en/test_multiple_piping.json ./temp_directory -r "../../base_pages" -s spec/test_multiple_piping.spec.js
If you have already built the generated pages, then the functional tests can be executed with:
yarn test_functional
This can be limited to tests under a directory with:
yarn test_functional --path tests/functional/spec/components/
To run a single test, add @watch into the name of any describe or it function and run:
yarn test_functional --watch
An example of adding @watch looks like this:
describe('@watch Skip Conditions', function() {...} or
it('@watch Given this is a test', function() {...}
To run the tests against a remote deployment you will need to specify the environment variable of EQ_FUNCTIONAL_TEST_ENV eg:
EQ_FUNCTIONAL_TEST_ENV=https://staging-new-surveys.dev.eq.ons.digital/ yarn test_functional
You will need to install the EB CLI tools using PIP.
pip install --user awsebcli # install the eb cli tools
The Elastic Beanstalk CLI requires the presence of a requirements.txt file. To generate one with Pipenv use the following:
pipenv lock -r > requirements.txt
Initialise the project using the command
eb init --region eu-west-1
This will launch a wizard asking for the AWS credentials and some questions about the environment to create.
eu-west-1 is the name for Ireland. I chose the default application name.
Once completed, you can then deploy the application using the following command:
eb create
This will create the environment and spin up the application . Once the application has deployed you can use the following command to open it in a browser
eb open
We use flask-babel to do internationalisation. To extract messages from source, in the project root run the following command.
pipenv run pybabel extract -F babel.cfg -o app/translations/messages.pot .
This will extract messages and place them in the translations/messages.pot file ready for translation.
You should only need to create the language files once.
To create Welsh language files, run the following command
pipenv run pybabel init -i app/translations/messages.pot -d app/translations -l cy
To create the gaelic language files, use the following:
pipenv run pybabel init -i app/translations/messages.pot -d app/translations -l gd
Our current language translation service requires a .csv rather than a .po file. To convert a .po file to a .csv you'll need to install the Python translate-toolkit:
brew install translate-toolkit
To generate the .csv file:
po2csv app/translations/cy/LC_MESSAGES/messages.po app.translations/static-cy.csv
To convert back to a .po file:
csv2po app.translations/static-cy.csv app/translations/cy/LC_MESSAGES/messages.po
Important: There are some encoding issues when opening the .csv file in Excel. Opening in Google sheets and saving as a .xslx file resolves this.
To compile the language files for use in the application, use the following:
pipenv run pybabel compile -d app/translations
As strings are added to the application, you will need to update but not overwrite the translations for the various languages. To update the language strings, use:
pipenv run pybabel update -i app/translations/messages.pot -d app/translations

Integration with the survey runner requires the use of a signed JWT using public and private key pair (see https://jwt.io, https://tools.ietf.org/html/rfc7519, https://tools.ietf.org/html/rfc7515).
Once signed the JWT must be encrypted using JWE (see https://tools.ietf.org/html/rfc7516).
The JWT payload must contain the following claims:
- exp - expiration time
- iat - issued at time
The header of the JWT must include the following:
- alg - the signing algorithm (must be RS256)
- type - the token type (must be JWT)
- kid - key identification (must be EDCRRM)
The JOSE header of the final JWE must include:
- alg - the key encryption algorithm (must be RSA-OAEP)
- enc - the key encryption encoding (must be A256GCM)
To access the application you must provide a valid JWT. To do this browse to the /session url and append a token parameter. This parameter must be set to a valid JWE encrypted JWT token. Only encrypted tokens are allowed.
There is a python script for generating tokens for use in development, to run:
python token_generator.py
Setting the EQ_PROFILING environment variable to True will enable profiling of the application. Profiling information
will be collected per-request in the profiling directory where it can be examined using the Pstats Interactive Browser.
$ python -m pstats <filename>
will load the file into the interactive browser where it can be sorted and queried as required.
To visualise the profile, snakeviz can be used. This provides a nice interface with an 'icicle' graph:
# First combine all the profiles in the 'profiling' directory.
# Ensure you delete all the files in this directory before starting your profiling session
# This will create a file called `combined_profile.prof`
pipenv run python scripts/merge_profiles.py
snakeviz combined_profile.prof
To add a new dependency, use pipenv install [package-name], which not only installs the package but Pipenv will also go to the trouble of updating the Pipfile as well.
NB: both the Pipfile and Pipfile.lock files are required in source control to accurately pin dependencies.
If you're looking for the Survey Runner code from the Alpha then it has been renamed to: alpha-eq-survey-runner
