Literature Review Title: Software Testing Process Models Benefits&Drawbacks: a Systematic Literature Review 
Chapter Title:  TM1: 
1. Abstract of Cited Paper (BIB001):  In agile software development, industries are becoming more dependent on automated test suites. Thus, the test code quality is an important factor for the overall system quality and maintainability. We propose a Test Automation Improvement Model (TAIM) defining ten key areas and one general area. Each area should be based on measurements, to fill the gap of existing assessments models. The main contribution of this paper is to provide the outline of TAIM and present our intermediate results and some initial metrics to support our model. Our initial target has been the key area targeting implementation and structure of test code. We have used common static measurements to compare the test code and the source code of a unit test automation suite being part of a large complex telecom subsystem. Our intermediate results show that it is possible to outline such an improvement model and our metrics approach seems promising. However, to get a generic useful model to aid test automation evolution and provide for comparable measurements, many problems still remain to be solved. TAIM can as such be viewed as a framework to guide the research on metrics for test automation artifacts. 
2. Abstract of Cited Paper (BIB002):  The software testing phase, despite its importance, is usually compromised by the lack of planning and resources in industry. This can risk the quality of the derived products. The identification of mandatory testing-related practices may lead to the definition of feasible processes for varied sizes of software companies. In this context, this work aims at identifying a set of key practices to support the definition of a generic, streamlined software testing process, based on practices that are described in the TMMi (Test Maturity Model integration), and verify the alignment of the devised process with the TMMi levels. We have performed a survey amongst Brazilian software testing professionals who work in both academia and industry, in order to identify priority practices to build the intended, streamlined process; additionally, we applied a diagnosis tool in order to measure the level of TMMi which is fulfilled with the devised process. A set of 33 (out of 81) practices were ranked as mandatory by most of participants, which represents 40 % of the TMMi’s full set of practices; on the downside, a testing process that relies on this subset of TMMi practices does not fully fulfil level 2 (Managed) of the maturity model. The identified subset of practices can guide the definition of a lean testing process when compared to a process that includes all TMMi practices; it is expected that such a process encourages a wider adoption of testing activities in software development; even though the streamlined process does not encompass many practices that are spread across TMMi levels, a substantial subset of level 2 practices (Managed) should be accomplished with its adoption.
