    """SparkPost API integration tests

    These tests run against the **live** SparkPost API, using the
    environment variable `SPARKPOST_TEST_API_KEY` as the API key
    If that variable is not set, these tests won't run.

    SparkPost doesn't offer a test mode -- it tries to send everything
    you ask. To avoid stacking up a pile of undeliverable @example.com
    emails, the tests use SparkPost's "sink domain" @*.sink.sparkpostmail.com.
    https://support.sparkpost.com/customer/en/portal/articles/2361300-how-to-test-integrations

    SparkPost also doesn't support arbitrary senders (so no from@example.com).
    We've set up @test-sp.anymail.info as a validated sending domain for these tests.
