What Causes My Test Alarm? Automatic Cause Analysis for Test Alarms in System and Integration Testing

Driven by new software development processes and testing in clouds, system and integration testing nowadays tends to produce enormous number of alarms. Such test alarms lay an almost unbearable burden on software testing engineers who have to manually analyze the causes of these alarms. The causes are critical because they decide which stakeholders are responsible to fix the bugs detected during the testing. In this paper, we present a novel approach that aims to relieve the burden by automating the procedure. Our approach, called Cause Analysis Model, exploits information retrieval techniques to efficiently infer test alarm causes based on test logs. We have developed a prototype and evaluated our tool on two industrial datasets with more than 14,000 test alarms. Experiments on the two datasets show that our tool achieves an accuracy of 58.3% and 65.8%, respectively, which outperforms the baseline algorithms by up to 13.3%. Our algorithm is also extremely efficient, spending about 0.1s per cause analysis. Due to the attractive experimental results, our industrial partner, a leading information and communication technology company in the world, has deployed the tool and it achieves an average accuracy of 72% after two months of running, nearly three times more accurate than a previous strategy based on regular expressions.Comment: 12 page

A Value Chain Based Analysis of Electronic Commerce’s Transformation of China’s Pharmaceutical Industry

In this paper we explore the impact of electronic commerce on the industry structure and market power allocation of China’s pharmaceutical industry. Firstly, we describe the overall characteristics of the pharmaceutical Industry in general. Secondly, we develop a value chain based framework of analysis for China’s pharmaceutical industry. We divide the pharmaceutical industry value chain into three tiers: the initial market, the middle market and the end market. Based on these works, we analyze the profound impacts of Electronic Commerce on the transformation of China’s pharmaceutical Industry, with particular emphasis on the evolution of market structure and the re-allocation of market power due to the introduction of E-Commerce procedures
