(IJACSA) International Journal of Advanced Computer Science and Applications, Vol. 10, No. 7, 2019 Traceability Establishment and Visualization of Software Artefacts in DevOps Practice: A Survey D. A. Meedeniya1, I. D. Rubasinghe2, I. Perera3 Dept. of Computer Science and Engineering, University of Moratuwa, Sri Lanka Abstract—DevOps based software process has become the artefacts in the SDLC [2][3]. There are different forms of popular with the vision of an effective collaboration between the relationships between the homogeneous and heterogeneous development and operations teams that continuously integrates software artefacts. Some artefacts may be highly coupled, and the frequent changes. Traceability manages the artefact some may depend on other artefacts in different degrees, consistency during a software process. This paper explores the unidirectionally or bidirectionally. Thus, software artefacts trace-link creation and visualization between software artefacts, consistency management helps to fine-tune the software existing tool support, quality aspects and the applicability in a process. The incomplete, outdated software artefacts and their DevOps environment. As the novelty of this study, we identify the inconsistencies mislead both the development and maintenance challenges that limit the traceability considerations in DevOps process. Thus, artefact management is essential such that the and suggest research directions. Our methodology consists of changes are accurately propagated to the impacted artefacts concept identification, state-of-practice exploration and analytical review. Despite the existing related work, there is a without creating inconsistencies. Traceability is the potential to lack of tool support for the traceability management between relate artefacts considering their relationships [4][5]; thus, a heterogeneous artefacts in software development with DevOps solution for artefact management. -
Leading Practice: Test Strategy and Approach in Agile Projects
CA SERVICES | LEADING PRACTICE Leading Practice: Test Strategy and Approach in Agile Projects Abstract This document provides best practices on how to strategize testing CA Project and Portfolio Management (CA PPM) in an agile project. The document does not include specific test cases; the list of test cases and steps for each test case are provided in a separate document. This document should be used by the agile project team that is planning the testing activities, and by end users who perform user acceptance testing (UAT). Concepts Concept Description Test Approach Defines testing strategy, roles and responsibilities of various team members, and test types. Testing Environments Outlines which testing is carried out in which environment. Testing Automation and Tools Addresses test management and automation tools required for test execution. Risk Analysis Defines the approach for risk identification and plans to mitigate risks as well as a contingency plan. Test Planning and Execution Defines the approach to plan the test cases, test scripts, and execution. Review and Approval Lists individuals who should review, approve and sign off on test results. Test Approach The test approach defines testing strategy, roles and responsibilities of various team members, and the test types. The first step is to define the testing strategy. It should describe how and when the testing will be conducted, who will do the testing, the type of testing being conducted, features being tested, environment(s) where the testing takes place, what testing tools are used, and how are defects tracked and managed. The testing strategy should be prepared by the agile core team. -
Requirements Traceability Practices Guide
CDC UNIFIED PROCESS PRACTICE GUIDE REQUIREMENTS TRACEABILITY Document Purpose The purpose of this document is to provide guidance on the project management practice of Requirements Traceability and to describe the practice overview, requirements, best practices, activities, and key terms related to these requirements. In addition, templates relevant to this practice are provided at the end of this guide. Practice Overview Requirements traceability is an activity that is one part of an overarching requirements management practice and extends from requirements definition through to implementation. Requirements tracing is used to ensure that each step of the product’s development process is correct, conforms to the needs of prior and next steps, and conforms to the defined requirements. Requirements tracing is a technique that helps to ensure that the project delivers what stakeholders expect. If applied correctly requirements tracing is a practice that can greatly increase the quality and reliability of a project’s final product while minimizing costly rework resulting from requirements errors. Requirements tracing defines the ability to describe and follow the life of a requirement, in both a forward and backward direction, ideally through each step of the entire product’s life cycle. This is done by documenting and tracking traceability relationships between requirements. A traceability relationship is a dependency relationship between project and/or product elements. Similar to the way a dynamic project schedule may react to a change in one task, a change to a requirement element may also have a rippling effect on other elements. A well documented traceability relationship clearly defines requirement dependencies and allows for analysis of how changes in requirements affect other requirements and the project as a whole. -

Managing Project Requirements
MANAGING PROJECT REQUIREMENTS Course Materials The causes of the majority of failed IT projects can be traced to poor definition and understanding of requirements. Changing requirements causes more delays than any other cause. If you want to improve project performance you must improve the way you define and manage requirements. Requirements must be a clear description in a common language. They are the bridge between the customer who will describe, pay for, and use the solution and the technical community who will specify and provide the solution. Requirements must be unique, normalized, linked, complete, consistent, bounded, modifiable, configurable and granular. Participants will cultivate the skills needed to elicit full business information from the right stakeholders and, learn structured techniques to identify and present business requirements clearly and effectively.

Efficient Black-Box JTAG Discovery
Ca’ Foscari University of Venice Department of Environmental Sciences, Informatics and Statistics Master’s Degree programme Computer Science, Software Dependability and Cyber Security Second Cycle (D.M. 270/2004) Master Thesis Efficient Black-box JTAG Discovery Supervisor: Graduand: Prof. Riccardo Focardi Riccardo Francescato Matriculation Number 857609 Assistant supervisor: Dott. Francesco Palmarini Academic Year 2016 - 2017 Riccardo Francescato Matriculation Number 857609 Efficient Black-box JTAG Discovery, Master Thesis c February 2018. Abstract Embedded devices represent the most widespread form of computing device in the world. Almost every consumer product manufactured in the last decades contains an embedded system, e.g., refrigerators, smart bulbs, activity trackers, smart watches and washing machines. These computing devices are also used in safety and security- critical systems, e.g., autonomous driving cars, cryptographic tokens, avionics, alarm systems. Often, manufacturers do not take much into consideration the attack surface offered by low-level interfaces such as JTAG. In the last decade, JTAG port has been used by the research community as an entry point for a number of attacks and reverse engineering techniques. Therefore, finding and identifying the JTAG port of a device or a de-soldered integrated circuit (IC) can be the first step required for performing a successful attack. In this work, we analyse the design of JTAG port and develop methods and algorithms aimed at searching the JTAG port. More specifically we will provide an introduction to the problem and the related attacks already documented in the literature. Moreover, we will provide to the reader the basics necessary to understand this work (background on JTAG and basic electronic terminology). -
