Tests for r.basins.fill are broken

[pmav99]

These tests are broken both for python 2 and python 3:

• raster/r.basins.fill/testsuite/testrbf.py
• ​http://fatra.cnr.ncsu.edu/grassgistests/reports_for_date-2019-03-26-07-00/report_for_nc_spm_full_v2alpha_nc/raster/r.basins.fill/testrbf/index.html

Moreover, the testsuite ​overwrites the "elevation" and "geology" maps thus ruining the test dataset (at least on python 3):

before running the tests:

./exec_grass.sh r.univar elevation
Starting GRASS GIS...
Cleaning up temporary files...
Executing <r.univar elevation> ...
 100%
total null and non-null cells: 29535
total null cells: 0

Of the non-null cells:
----------------------
n: 29535
minimum: 89.6269
maximum: 134.301
range: 44.6739
mean: 116.855
mean of absolute values: 116.855
standard deviation: 9.32828
variance: 87.0169
variation coefficient: 7.98278 %
sum: 3451315.7405014
Execution of <r.univar elevation> finished.
Cleaning up default sqlite database ...
Cleaning up temporary files...

after:

./exec_grass.sh r.univar elevation
Starting GRASS GIS...
Cleaning up temporary files...
Executing <r.univar elevation> ...
 100%
total null and non-null cells: 29535

Of the non-null cells:
----------------------
n: 0
minimum: -nan
maximum: -nan
range: -nan
mean: -nan
mean of absolute values: -nan
standard deviation: -nan

Until someone finds the time to fix them, please add the following decorator on the Test class:

import unittest

@unittest.skip("See #3822")
class TestRasterbasin(TestCase):
    # ...

Update map names to those used in nc_spm_full_v2alpha

After renaming the maps (see attached patch) the test passes here.

Does it make sense to adjust tests to a test mapset that is 1) not available, 2) in alpha state?

It is available: ​http://fatra.cnr.ncsu.edu/data/

2) in alpha state?

In the end I only restored the names of the standard sample data set and found that the tests works.

After applying the patch, the tests do pass, but the "elevation" map still gets corrupted.

In 74423:

deactivate erroneous test; see #3822

[sbl]

The test actually only tests if the module works, but contains additinal tests that have nothing to to with the module in question (and rather tests data or other modules). Took the liberty to deactivate the test until fixed with proper test cases.
