nixos/testing: Use stripped down tesseract only.
Only include the English language for the VM tests, because we most
likely won't need other languages. At least for now.

nixos/test-driver: Make tesseract OCR optional.
By default this is now enabled, and it has to be explicitely enabled
using "enableOCR = true". If it is set to false, any usage of
getScreenText or waitForText will fail with an error suggesting to pass
enableOCR.

This should get rid of the rather large dependency on tesseract which
we don't need for most tests.

Note, that I'm using system("type -P") here to check whether tesseract
is in PATH. I know it's a bashism but we already have other bashisms
within the test scripts and we also run it with bash, so IMHO it's not a
problem here.

nixos/test-driver: Add new getScreenText function.
Basically, this creates a screenshot and throws tesseract at it to
recognize the characters from the screenshot. In order to produce a
result that is well enough, we're using lanczos scaling and scale the
image up to 400% of its original size.

This provides the base functionality for a new Machine method which will
be called waitForText. I originally had that idea long ago when writing
the VM tests for VirtualBox and Chromium, but thought it would be
disproportionate to the case.

The downside however is that VM tests now depend on tesseract, but given
the average runtime of our tests it really shouldn't have a too big
impact and it's only a runtime dependency after all.

Another issue is that the OCR process takes quite some time to finish,
but IMHO it's better (as in more deterministic) than to rely on sleep().

Eelco Dolstra 13dcb35233 VM tests: Don't produce output on failure
Producing output makes it hard to restart builds that failed for
intermittent reasons (like timeouts). So let's not do that.

Eelco Dolstra 51c349d0cc test-driver: Use netpbm instead of imagemagick
Imagemagick pulls in 100s of megabytes of dependencies.

Bjørn Forsman 8e8f95beda nixos/test-reports: use local copy of jquery
The current way test reports get jquery,

  src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"

only works when getting reports over http:// or https://, not file://.
Change it so that it works for all protocols by using a local copy of
jquery.

This fixes the issue where locally created and browsed test reports
cannot be navigated properly; clicking the '+' symbol to expand
sub-sections doesn't work.

Eelco Dolstra b599deedb4 makeTest: Pass nodes attribute
This allows doing things like:

  nix-build nixos/tests/misc.nix -A nodes.machine.config.system.build.initialRamdisk

Eelco Dolstra 36c05d5e5b Simplify running tests even further
Now you can just say:

  $ nix-build '<nixos/tests/login.nix>'

You can still get the driver script for interactive testing:

  $ nix-build '<nixos/tests/login.nix>' -A driver
  $ ./result/bin/nixos-test-driver

Eelco Dolstra abe218950c Make it easier to run the tests
You can now run a test in the nixos/tests directory directly using
nix-build, e.g.

  $ nix-build '<nixos/tests/login.nix>' -A test

This gets rid of having to add the test to nixos/tests/default.nix.
(Of course, you still need to add it to nixos/release.nix if you want
Hydra to run the test.)

Eelco Dolstra 497997cc38 Move generation of coverage reports from nixos/lib/testing to releaseTools
Also, turn some stdenv adapters into setup hooks.

Eelco Dolstra 6dafee8d67 Fix runInMachine
It requires a writable /nix/store to store the build result.  Also,
wait until we've reached multi-user.target before doing the build, and
do a sync at the end to ensure all data to $out is properly written.
