Testing sugar modifications

@environment decorator now clones separate test cases for every environment. So,
 It's allows us to run tests in parallel, increased logging clearness.

Test report example (compare execution time with multiprocess):
```

Setup errors now passed to child tests. So, is setup in error, tests are also marked errored:
```

please add some environment names that are normed, to ensure that current_environment is in denormed state
