Test Data Management
Robustness, and efficiency can be measured with the test data alone.
People often discuss about the test cases, how many test cases are identified? how many are passed or failed? But instead, we should be focusing more on the test data.
We will be spending significant amount of time in test case design with different data inputs.
It is crucial in identifying how the software behaves in different parameters and different conditions. Be it valid or invalid data.
