System testing method based on scattered points

The invention discloses a system testing method based on scattered points. When system testing is carried out, the entire business process of the system to be tested is firstly divided into a plurality of units, and each unit comprises at least one function node; and then, each function node of each unit is split into testing scattered points, and all testing scattered points of each unit are permutated and combined to test. With the testing method based on the scattered points, more complete testing points can be covered more deeply, product quality can be better ensured, and the robustness and the stability of the system are increased.
