[netjsonconfig-tests] Avoid error logging to print noisy output during tests

[nemesifier]

Depends on openwisp/openwisp-utils#98.

Use the decorators mentioned in the issue linked above to silence the output of noisy tests.

Hello,
when I run the tests, I get the following output

....................................................................................................................................................................................................................................................................................................Unrecognized config block was skipped:

{
    "unrecognized": true
}


.....................................................
----------------------------------------------------------------------
Ran 345 tests in 10.715s

OK

Please how can I know the exact test that runs and generates the output, Unrecognized config block was skipped for example like an additional parameter that I can append to the ./runtests.py

@lehone-hp I wanted to ask how exactly did you come to know that what file in the tests folder we have to use the decorators in ?

@lehone-hp I wanted to ask how exactly did you come to know that what file in the tests folder we have to use the decorators in ?

I ran the tests with the -v flag; ./runtests.py -v, it lists all the tests methods as they run.

@lehone-hp but when I run ./runtests.py -v command for solving issue https://github.com/openwisp/openwisp-controller/issues/187 to know which test methods are giving noisy outputs I get this error :

Can you help me out in this ?
./runtests.py shows this :

Thank You
