## automated testing
|
|||
|
|
|
|||
|
|
Automated tests could make it safer to contribute code, easier to review new code, and much easier to refactor, or upgrade Python dependencies.
|
|||
|
|
|
|||
|
|
To run tests:
|
|||
|
|
1. create a Postgres database called `capsulflask_test`
|
|||
|
|
- e.g.: `docker exec -it d1702306f409 psql -U postgres createdb -O postgres capsulflask_test;`
|
|||
|
|
- (`d1702306f409` is the docker container ID of the postgres container)
|
|||
|
|
2. run `python -m unittest`
|
|||
|
|
|
|||
|
|
### Architecture
|
|||
|
|
|
|||
|
|
I tried to make the absolute minimal changes to be able to override settings in tests – possible alternative approaches include accepting an argument to create_app() to define which env file to load, or adding conditional logic to create_app() to pre-load specific settings before running load_dotenv() – but allowing env vars to override dotenv vars seemed cleanest. (Thanks @forest for improving on this approach)
|
|||
|
|
|
|||
|
|
### Creating test databases
|
|||
|
|
|
|||
|
|
One outstanding question is how to initialise/reinitialise the test database.
|
|||
|
|
|
|||
|
|
Currently, the tests rely on the existence of a capsulflask_test database on localhost, accessible by the postgres user with password dev.
|
|||
|
|
|
|||
|
|
I create this manually using:
|
|||
|
|
`docker exec -it d1702306f409 psql -U postgres createdb -O postgres capsulflask_test;`
|
|||
|
|
|
|||
|
|
where `d1702306f409` is the docker container ID of the postgres container.
|
|||
|
|
|
|||
|
|
In between test runs, you can either drop and recreate that database, or manually clear data using:
|
|||
|
|
|
|||
|
|
`docker exec -it d1702306f409 psql -U postgres capsulflask_test -c "DELETE FROM vms; DELETE FROM login_tokens; DELETE FROM ssh_public_keys; DELETE FROM api_tokens; DELETE FROM accounts;`
|
|||
|
|
|
|||
|
|
### Test coverage
|
|||
|
|
|
|||
|
|
This tests the "landing" (public) pages, login, capsul index and creation. I didn't add automated coverage reporting yet, unclear if that seems useful.
