Test data
Audit test data
Audit test data is used to test the existence and effectiveness of controls built
into an application program used by an audit client. As such, dummy
transactions are processed through the client’s computerised system. The
results of processing are then compared to the auditor’s expected results to
determine whether controls are operating efficiently and systems’
objectiveness are being achieved. For example, two dummy bank payment
transactions (one inside and one outside authorised parameters) may be
processed with the expectation that only the transaction processed within the
parameters is ‘accepted’ by the system. Clearly, if dummy transactions
processed do not produce the expected results in output, the auditor will need
to consider the need for increased substantive procedures in the area being
reviewed.
