| The customer |
| US-based technology
leader in enterprise databases |
| |
| The challenge |
For a feature of the RDBMS
 |
Reduce test
execution time from 48 hours to less than
4 hours |
 |
Optimize number of test
cases from 117 to less than 50 |
 |
Across multiple platforms
of different configurations |
 |
Responsible for entire
test cycle: System test strategy, test case
optimization & implementation |
|
| |
| The solution |
 |
Re-writing
test cases using Orthogonal Arrays (OA) -
Identified 13 parameters and 36 test cases |
 |
Used Design of Experiments
(DOE) - search strategy to determine source
of defect |
|
| |
| The benefits |
 |
Execution
time is reduced by 90% |
 |
Result analysis time reduced
by 80% |
 |
95% code coverage |
 |
40% increase in overall
productivity |
