Which of the following could be useful during system testing?
stubs
data flow analysis
capture-replay tools
*unit-style automated oracles
mock objects

Stubs, data flow analysis, capture-replay tools and mock object are useful during the system testing.

Explanation:

Stubs hold the predefined data and used it to answer calls during testing. Stub act as an object and test scrub simulated the charactertics of software components.

Data flow analysis used in the programming of software components by using the control flow graph. It basically focused on the data variable and their definite values. It is used in the form of whitepox testing.

Capture replay tool is used as aggression development test and during testing it records all the events. By using playback it also compared the results in the testing.

Mock object are used to verified all the expected results and behavior during testing. Mock objects are mainly used in unit testing.
