Test Cleanup
Some errors and failures are occurring in test_Item.
Cause:
- The error is assertion error from util.kvstore due to unicode and str mismatch there.
Work:
- Traced the test to find the reason of such difference in asserion
- The errors were mostly in value-type for items. Found out how the values-types are created at given instances and their respective unicode and str values
- worked on tracing the execution of code in kvstore as how sqla gets the type of value-type there.
