In server applications, threads are created to handle incoming requests. Since threads consume significant resources including CPU cycles and memory, it is important to control the number of threads that are created. In this paper, we introduce a lightweight, static approach to detecting unbounded thread- instantiation loops that may exist in a server application. The key observation of our approach...
The input space of a system must be modeled before combinatorial testing can be applied to this system. The effectiveness of combinatorial testing to a large extent depends on the quality of the input space model. In this paper we introduce an input space modeling methodology for combinatorial testing. The main idea is to consider the process of input space modeling as two steps, namely, input structure...
Combinatorial testing has attracted a lot of attention from both industry and academia. A number of reports suggest that combinatorial testing can be effective for practical applications. However, there are few systematic, controlled studies on the effectiveness of combinatorial testing. In particular, input parameter modeling is a key step in the combinatorial testing process. But most studies do...
In this paper we present a case study of applying combinatorial testing to test a combinatorial test generation tool called ACTS. The purpose of this study is two-fold. First, we want to gain experience and insights about how to apply combinatorial testing in practice. Second, we want to evaluate the effectiveness of combinatorial testing applied to a real-life system. ACTS has 24637 lines of uncommented...
Manually generating navigation graphs for dynamic Web applications is a challenging task because of the page explosion problem, i.e., the astronomical number of dynamic pages in a dynamic web application. To generate navigation graphs practically, this paper presents Tansuo, a tool for semiautomatically generating navigation graphs for dynamic web applications. Tansuo has two novelties: (1) solving...
