• move stock npy arrays to iris-test-data stock arrays iris-test-data#45
• update skip_data pattern usage
• alter minimal testing environment to not use test_data

I don't see the need for this..
From how iris.config.TEST_DATA_DIR is initialised in iris.config, I think this can't be empty ?

[marqh]

it can occur, here:
https://github.com/SciTools/iris/blob/master/lib/iris/config.py#L138

override = os.environ.get("override_test_data_repository")
if override:
    if override == '1':
        TEST_DATA_DIR = None
    else:
        TEST_DATA_DIR = override

I thought there would be more examples of a GraphicsTest overriding setUp.
However, this seems to be the only one.

Needs to call the class setUp here :
super(TestBasic, self).setUp()

As a cross-check, I ran all tests with control exports:

• export override_test_data_repository=1 : breaks the config.TEST_DATA_DIR value
• export IRIS_TEST_NO_DATA=1 : force everything wrapped in "skip_data" to skip

The only failure is this one :

iris.tests.experimental.regrid.test_regrid_conservative_via_esmpy.TestConservativeRegrid.test_multidimensional

So, that needs wrapping with "skip_data".
