Following files were too low on code coverage,
so the coverage has been enhanced with addition of more unit-tests.
- troveclient/client.py
- troveclient/v1/shell.py
The methodology to test shell.py has been motivated from the
one used by python-novaclient to test novaclient/v2/shell.py
Also, found an unmocked entry in test_secgroups.py,
which was causing intermittent failure while
writing the tests for shell.py.
