Ensuring Calender Compliance - an essential part of the testing cycle

The criticality of dates

A large number of mission-critical applications contain date or time sensitive processing logic that can be misinterpreted or deemed difficult to test, for example for:

• the first or last day of the month
• the first or last business day of the weekend of quarter or financial year
• public holidays such as Christmas
• the clock rollover at midnight, and so on

Ensuring compliance

In a quality-conscious environment an essential part of the final testing of any changes to such applications should be to test them with date conditions to which they may be sensitive to obtain Calender Compliance. Ideally, a set of test scripts, which exercise the application for significant dates, could be run as a standard step in the final stages of the testing cycle, as shown in the following illustration of a possible development cycle.
