Testing

WARNING - running the tests will cost you money!

To run the tests various environment variables must be set. These are:

• MG_DOMAIN is the domain name - this is a value registered in the Mailgun admin interface.
• MG_PUBLIC_API_KEY is the public API key - you can get this value from the Mailgun admin interface.
• MG_API_KEY is the (private) API key - you can get this value from the Mailgun admin interface.
• MG_EMAIL_TO is the email address used in various sending tests.

and finally

• MG_SPEND_MONEY if this value is set the part of the test that use the API to actually send email will be run - be aware this will count on your quota and this will cost you money.
