Test Workload Estimation
Bernard Homès · 2022
It is always difficult to correctly estimate the test workload necessary to identify the defects present in a system; this is all the truer in a system-of-systems and in systems already developed whose size and complexity were not measured. The workload will depend on different aspects. Evaluating test effort or workload may seem akin to searching for information in a crystal ball, coffee grounds or tea leaves. The principle of Work Breakdown Structure and its extension to Test Breakdown Structure divides each task of the project into one or more tasks of smaller size, until obtaining individual tasks of small cut. In Agile methods, the estimation is the responsibility of the Dev teams and is carried out at each iteration. Estimation techniques used, in addition to experience-based techniques, involve Planning Poker. Component coverage covers every component, from requirements to test cases.
