Q

Should test data be backed up prior to first to use?

A

yes

24
Q

Test data management

A

A defined strategy for the development, used, maintenance, and ultimately destruction of test data

25
Q

Test data

A
  • Data points required to test most apps
  • helps confirm expected results
  • verify software behaves correctly for invalid input data
26
Q

challenges with using commercial off the shelf (COTS)

27
Q

commercial off-the-shelf

COTS

A
