[Bug 1453509] Re: autopkgtest behaves differently depending on the order of the arguments

[Martin Pitt]

adt-run is designed to run an arbitrary number of tests on the command
line; see the manpage:

    TEST OPTIONS
           Unless stated otherwise, these affect all subsequent test arguments.

    (-B, --built-binaries, --control-override)

For the record, I think that makes command line parsing and
understanding unnecessarily complex and introduces this kind of
positional dependency. But it has been adt-run's CLI interface since
pretty much day one, so I'm a bit hesitant to change it. IIRC Rodney
Dawes was complaining about this as well a while ago, subscribing him
for his interest.

I retitle this to rearrange the CLI to only accept exactly one test,
then the test modifications like --built-binaries, --control-override,
or --click-source can occur anywhere.

Title:
  simplify command line by only allowing exactly one test argument

Status in autopkgtest package in Ubuntu:
  Triaged

Bug description:
  autopkgtest for a dkms module with autodep8.

  Content of local control file:
  '''
  Test-Command: /non-existent
  Restrictions: needs-root, allow-stderr
  Depends: dkms
  '''

  This command fails (as expected)
  adt-run -d --override-control=dkms/dkms.control asic0x --- qemu adt-vivid-amd64-cloud.img

  But this command passes:
  adt-run asic0x -d --override-control=dkms/dkms.control --- qemu adt-vivid-amd64-cloud.img

  In the second case, the test uses the control file generated by
  autodep8 instead of the control file provided on the command line.
