Tests

This dalec uses Radicale as tiny python caldav server wich can runs inside tox out of the box. If you want to test with other caldavs servers, you can add a local_settings.py file in tests/ folder and add a dict conf of extra calendars DALEC_EXTRA_CALDAV_URLS:

DALEC_EXTRA_CALDAV_URLS = {
    "nextclould-v27-public": {
        "url": "https://nextcloud.example.com/remote.php/dav/public-calendars/saiGzyBYcWct24W8/",
    },
    "nextclould-v27-auth": {
        "url": "https://nextcloud.example.com/remote.php/dav/calendars/username/calendarname/",
        "username": "username",
        "password": "secret",
    },
    "my-other-caldav-events": {
        "url": "https://caldav.example.com/xxx/",
    },
}

This will perform simple test to check the proxy seems to work with this type of caldav server:

• try to fetch events
• assert there is at least 1 event fetched.

If your calendar has no event, test will fail.
