Quality Testing Services: Static and Dynamic Methods
Static methods. The most simple and easy to implement solution is to construct each program path through its gradual extension by adding arcs, until the top of the program control flow graph is reached. This idea can be improved by means of so-called adaptive methods, which each and every time add only one test path (input test) using the previous paths (tests) as a guide for the selection of subsequent paths in accordance with a certain strategy. In most cases, adaptive strategies apply to the criterion C1 (decision / path coverage criterion). The main disadvantage of static methods is that they do not consider possible non-implementability of generated test paths. Resorting to quality assurance services you will be able to achieve all your testing goals and, as a result, deliver the highest quality software to your customers.
Dynamic methods. Such methods involve the construction of a complete test system that meets a specified criterion by simultaneously solving the task of generating multiple covering paths and test data. At that it is possible to automatically take into account the implementation or non-implementation of previously considered paths or their parts. The basic idea of dynamic methods is the connection of the subsequent parts to their initial path segments to be implemented so that: 1) not to lack the implementation of newly created paths; 2) cover the required elements of the program structure. Application testing services are destined to deal with all kinds of software problems and prepare the products for their successful release.
Path implementation methods. This technique involves separating a subset of the paths to be implemented from a plurality of paths. After that, multiple covering paths are generated from the resultant subset of paths being executed.
The advantage of static methods is that they require a relatively small amount of necessary resources, either in use or during development. However, their implementation may cause significant issues, leading to unpredictable defect rate (unimplemented paths). Furthermore, in these systems, the transition from multiple covering paths to a complete test system must be manually performed by the user, and this work is quite time-consuming. Dynamic methods require considerably more resources in both the development and the operation; however, there is an increase in costs mainly due to the development and operation of the device determining the implementability of the path (a symbolic interpreter, solver of inequalities). The advantage of these methods lies in the fact that their products meet a certain level of quality – the excitability of paths. Path implementation methods produce the best result. QA as a service is a way to improve the quality without spending much money.
