Bug#850494: how to force a test that has breaks-testbed set?

[evgeni@debian.org (Evgeni Golov)]

Package: autopkgtest
Version: 4.2.2
Severity: minor
Tags: upstream

Ohai,

the docs say:

breaks-testbed
    The test, when run, is liable to break the testbed system. This
    includes causing data loss, causing services that the machine is
    running to malfunction, or permanently disabling services; it does
    not include causing services on the machine to temporarily fail.

    When this restriction is present the test will usually be skipped
    unless the testbed's virtualisation arrangements are sufficiently
    powerful, or alternatively if the user explicitly requests.

However, I could not find any docs how to "explicitly request" this.

Background: I am running the tests inside a docker container (on
travis-ci.org, via travis.debian.net) and that gets thrown away after
the tests anyways.

Regards
Evgeni
