Subject [jira] Created: (DERBY-4209) Stabilize and investigate failures in MogTest
Date Mon, 04 May 2009 05:21:30 GMT
Stabilize and investigate failures in MogTest
---------------------------------------------

                 Key: DERBY-4209
                 URL: https://issues.apache.org/jira/browse/DERBY-4209
             Project: Derby
          Issue Type: Bug
          Components: Test
    Affects Versions: 10.5.1.1, 10.6.0.0
            Reporter: Kristian Waagan


MogTest uses a random seed to generate a test configuration, and for some seeds the test fails.
It is unclear whether these failures are test failures or a Derby product issue.
So far two types of failures has been observed:
 a) Error too big between calculations (SQL and Java).
 b) Differing number of buckets in calculations.

See DERBY-4085 for examples of seeds causing failures.
The test was contributed as part of DERBY-646.
