REAL LIFE TEST

    With the real life test, it is not the intention to test the system behaviour in separate situations, but to simulate the realistic usage of the system in a statistically responsible way. This test mainly focuses on characteristics, such as effectivity, connectivity, continuity and performance of the system under test. To be able to test whether a system can handle realistic usage of it, that usage should be somehow specified. This also serves as a test basis and, in this context, is often referred to as the profile. The two most common types are: operational profile and load profile. The following questions may constitute an explicit part of the review within the framework of the real life test:
•    Has the expected frequency of use been described on a function level?
•    Has it been described for each type of user which functions may be carried out?
•    Has it been described for each function when it will be used (daily, weekly, annually, daytime, evening)?
•    Is there insight in the relationship between the various batch procedures across the (sub) systems?
•    Has the configuration for the production environment been described (hardware, network, system software, DBMS, etc.)?
•    Have specific requirements been set for the performance of online functionality?
•    Is a distinction being made between the response time when starting up a function and the screen change within a function?
•    Have specific performance requirements been set for data retrieval and manipulation?
•    Have specific performance requirements been set for batch functionality?
•    Have specific requirements been set for memory usage?
•    Are there any requirements for the number of database calls per transaction?
•    Are there any requirements for the maximum page and buffer sizes?
•    Are there any requirements for the size of the application and/or the database?
