[Question] Enable test mode for Mailgun in settings.py

[rick020]

According to the docs it is possible use the test mode in Mailgun by calling.

message = AnymailMessage(...)
message.esp_extra = {
    'o:testmode': 'yes',  # use Mailgun's test mode
}

Is it also possible to enable the test mode settings.py?

Yes, you can use Anymail's global send defaults settings to provide default attributes for every message sent through Anymail:

# settings.py
ANYMAIL = {
    ...
    "MAILGUN_SEND_DEFAULTS": {
        "esp_extra": {"o:testmode": "yes"},
    },
}

(Incidentally, Anymail's Mailgun live integration tests use this exact setting to help ensure they don't accidentally send real messages.)
