For extensive software testing, normally multiple testing methods are used to test multiple objects. The testing activities spread out over time, lasting over months or even more than a year. Software testing is generally divided into different sub-stages to permit testing to be performed in a smaller, more compliant scale.

Software Testing Sub-Stages This picture elucidates the software testing sub-stages through the use of V-model, a variation of the generally used waterfall process with an accent onverification and validation.

It demonstrates an annotated V-model with supplementary data about the specific testing substages. All the sub-stages not included in the original V-model are demonstrated in red ovals, with their interrelation to the other sub-stages. There are some key moments about these sub-stages: •

In the case if software bugs are reported by clients at the time of operational use, diagnosis testing may be used to recreate and diagnose the defects.

Controlled product release and operational use by limited clients lead to beta testing. Beta testing may be supplementary testing sub-stage closely linked to operational use. It usually straightly precedes the operational use. Acceptance testing is attached to the end of system testing, because it is normally conducted right after system testing to define if the software product should be released. System testing, integration testing and component testing have already been represented in the V-model. Unit testing is depicted as is, both as a sub-stage of software testing and as a part of the coding-and-unit-testing stage. Regression testing normally spreads over the general test activities for new product releases based on previous ones or other equal products. Nevertheless, as soon as a serious part of the existing product is used, the accent of regression testing is normally on the integration testing substage and subsequently, where old and new product elements are integrated.
