Testing
How to run tests locally.
When a PR is submitted, a series of tests will be run with Github actions. Our tests can be categorised into two:
- Backend / Python tests
- Frontend tests with Cypress, Selenium and Jest
It is fine to just submit your PR and let the tests run on Github. However, if the tests fail, you may need to run the tests locally to investigate what's going on, then either fix the tests, or fix your code.
To run Python tests, simply run at the top folder of the repository:
pytest
We are aiming to migrate all unittest to pytest. Meanwhile you will see a combination of these. If you write new tests, please use pytest.
For Rapid Router and Portal,
pytest also runs Selenium tests. Check the section below for what you need to install to run it.The Python tests in Portal also include some snapshot tests.
Running
pytest will also automatically run the snapshot tests. When needed, the snapshot tests can be updated by running pytest --snapshot-update.To run Cypress tests locally, you need two shell windows.
Shell #1
The following will run the portal/game on local server.
In aimmo:
./run.py
In Portal:
./run
Shell #2
This will run the Cypress tests in the terminal.
In aimmo:
cd game_frontend
yarn run cypress run
In Portal:
yarn run cypress run
If you want to view the tests as they run using Cypress' test runner window, you can run:
yarn run cypress open
Selenium is a frontend test framework that is used in Rapid Router and in Portal. We aim to gradually migrate Selenium tests to Cypress.
To run Selenium tests you need to install chromedriver. Please check here on how to install for your OS.
Similar with Cypress, it will launch a browser windows and you should be able to see a series of frontend actions.
These can be run locally with the following:
cd game_frontend
yarn test
If needed, the snapshot tests can be updated with the following:
yarn test -u
