Playback Testing Using Log Files
Most testers are familiar with record/playback testing. A variation of this approach
is log playback testing. Instead of explicitly recording the user actions using
a recorder, this technique simply relies on the information in the log file produced
by the system under test to play back the scenario. This is extremely useful for
reproducing issues reported by customers which are typically hard to reproduce otherwise
due to lack of detailed repro steps. This approach also lends itself well to creating
data driven tests and can be used to augment the existing test automation.
Testing and investigating failures in a non-deterministic software system can be
very costly and painful. In most cases the only source of information to know what
code path got exercised are the log files produced by the application. This paper
talks about how the information in log files can be used to playback the sequence
of actions to test specific code paths and also reproduce bugs. We will look at
exploring an extension of this approach and how log files can be used as a source
for data driven testing by simply varying the sequencing of actions that are played
back. This paper illustrates the technique using real a world example. Finally the
paper discusses the benefits and how it can be applied to different test domains.

Software Testing Certificate Program
This program enables individuals who have basic computer experience to make a career change into the software industry. The program is also ideal for those who are already testers and wish to gain professional training. This set of three classes is offered again this spring.
