The use of clues (i.e. symptoms of the error and/or the results of one or more test cases) and relationships among the clues to determine where the error lies.

58
Q

Debugging by Deduction

A

The use of the processes of elimination and refinement to debug a program.

59
Q

Debugging by Backtracking

A

The process of stepping backwards through the logic of a program until the programmer finds the point at which the logic went astray.

60
Q

Debugging by Testing

A

The use of test cases specifically for debugging, to cover only a single condition or a few conditions for scrutiny.

61
Q

XP Testing

A

Continuous unit testing comprises the bulk of the testing effort although acceptance testing also falls under this principle.

verify that separate systems can work together passing data back and forth correctly
