    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.

    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).

  • Acceptance Testing Based on Relationships Among Use Cases Susumu Kariyuki, Atsuto Kubo Mikio Suzuki Hironori Washizaki, Aoyama Media Laboratory TIS Inc
    5th World Congress for Software Quality – Shanghai, China – November 2011 Acceptance Testing based on Relationships among Use Cases Susumu Kariyuki, Atsuto Kubo Mikio Suzuki Hironori Washizaki, Aoyama Media Laboratory TIS Inc. Yoshiaki Fukazawa Tokyo, Japan Tokyo, Japan Waseda University [email protected]. [email protected] Tokyo, Japan jp [email protected] [email protected] Abstract In software development using use cases, such as use-case-driven object-oriented development, test scenarios for the acceptance test can be built from use cases. However, the manual listing of execution flows of complex use cases sometimes results in incomplete coverage of the possible execution flows, particularly if the relationships between use cases are complicated. Moreover, the lack of a widely accepted coverage definition for the acceptance test results in the ambiguous judgment of acceptance test completion. We propose a definition of acceptance test coverage using use cases and an automated generation procedure for test scenarios and skeleton codes under a specified condition for coverage while automatically identifying the execution flows of use cases. Our technique can reduce the incomplete coverage of execution flows of use cases and create objective standards for judging acceptance test completion. Moreover, we expect an improvement of the efficiency of acceptance tests because of the automated generation procedure for test scenarios and skeleton codes. 1. Introduction An acceptance test is carried out by users who take the initiative in confirming whether the developed system precisely performs the requirements of the users.2) As a method of representing functional requirements, use cases have been used.3) Use cases are descriptions of external functions of a system from the viewpoint of the users and external systems (both are called actors).

  • Automatic Generation of Test Cases from Use-Case Diagram
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Gunadarma University Repository Proceedings of the International Conference on C-24 Electrical Engineering and Informatics Institut Teknologi Bandung, Indonesia June 17-19, 2007 Automatic Generation of Test Cases from Use-Case Diagram Noraida Ismail 1*, Rosziati Ibrahim2, Noraini Ibrahim1 1Faculty of Information Technology and Multimedia, 2Research Management and Innovation Center (RMIC) University of Technology Tun Hussein Onn Malaysia (UTHM). Parit Raja, Batu Pahat, Johor, Malaysia. Intelligent searching techniques have been developed in order to provide a solution to the issue of finding information relevant to the user needs, and the problem of information overload - when far too much information is returned from a search. We employ this technique to introduce an automatic tool which used to generate the test cases automatically according to the system’s requirement. The tool uses two steps for generating test cases. First, the system’s requirements are transformed into a Unified Modeling Language (UML) Use-case Diagram. Second, the test cases will be automatic generated according to the use cases respectively. In the workspace, the ToolBox is used in order to ease the drawing of the use-case diagram. As well as allowing a user to layout the requirements of the system via a use-case diagram in the provided workspace, a user also may type-in the properties for each of the use cases used. Once the use- case diagram has been finalized, it can be save for further used and modification. The engine of the tool will take the use cases from the use-case diagram and search the query string (keyword) used in the tool’s library.

Since Unified Modeling Language (UML) is the most widely used language, many researchers are It has been proven that the software testing phase is using UML diagrams such as state diagrams, use-case one of the most critical and important phases in the diagrams and sequence diagrams to generate test cases software development life cycle. In general, the and this has led to model-based test case generation software testing phase takes around 40-70% of the techniques. In this paper, an approach with additional effort, time, and cost.

Learn More Introduction Agile software development has now become the norm, and over time, software testing has also evolved to firmly embed itself in the agile process. Some intrinsic activities pertaining to software testing have remained largely unchanged with suitable adaptations to align towards agile (such as test case design and execution, defect logging and triaging). However, one important aspect that has been heavily impacted (due to short release cycles and paucity of time) is documentation. This paper highlights some important considerations for documentation in the context of agile testing. Waterfall vs agile – A comparison The waterfall approach to software development was relatively easier as each activity pertaining to software testing was individually bucketed (i.e. test requirement gathering, test design phase, test execution phase, defect logging, etc.). Teams also had the luxury of being able to take weeks (if not months) to complete each activity. Consequently, each phase came with robust documentation as part of the deliverable - to be used in the subsequent phase. Every project was typically supported by a detailed test strategy document, comprehensive test plan, detailed test cases, test execution report, defect triage report, etc.

  • Automatic Test Cases Generation from Software Specifications
    e-Informatica Software Engineering Journal, Volume 4, Issue 1, 2010 Automatic Test Cases Generation from Software Specifications Aysh Alhroob∗, Keshav Dahal∗, Alamgir Hossain∗ ∗School of Computing , Informatics and Media, University of Bradford amhalhro@ bradford.ac.uk, k.p.dahal@ bradford.ac.uk, m.a.hossain1@ bradford.ac.uk Abstract A new technique is proposed in this paper to extend the Integrated Classification Tree Method- ology (ICTM) developed by Chen et al. [13] This software assists testers to construct test cases from functional specifications. A Unified Modelling Language (UML) class diagram and Object Constraint Language (OCL) are used in this paper to represent the software specifications. Each classification and associated class in the software specification is represented by classes and at- tributes in the class diagram. Software specification relationships are represented by associated and hierarchical relationships in the class diagram. To ensure that relationships are consistent, an automatic methodology is proposed to capture and control the class relationships in a systematic way. This can help to reduce duplication and illegitimate test cases, which improves the testing efficiency and minimises the time and cost of the testing. The methodology introduced in this paper extracts only the legitimate test cases, by removing the duplicate test cases and those incomputable with the software specifications. Large amounts of time would have been needed to execute all of the test cases; therefore, a methodology was proposed which aimed to select a best testing path. This path guarantees the highest coverage of system units and avoids using all generated test cases. This path reduces the time and cost of the testing.

  • What Is a Good Test Case? Cem Kaner, J.D., Ph.D
    What Is a Good Test Case? Cem Kaner, J.D., Ph.D. Florida Institute of Technology Department of Computer Sciences [email protected] STAR East, May 2003 This research was partially supported by NSF Grant EIA-0113539 ITR/SY+PE: "Improving the Education of Software Testers." Any opinions, findings and conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation (NSF). Abstract Designing good test cases is a complex art. The complexity comes from three sources: Test cases help us discover information. Different types of tests are more effective for different classes of information. Test cases can be “good” in a variety of ways. No test case will be good in all of them. People tend to create test cases according to certain testing styles, such as domain testing or risk-based testing. Good domain tests are different from good risk-based tests. What’s a Test Case? Let’s start with the basics. What’s a test case? IEEE Standard 610 (1990) defines test case as follows: “(1) A set of test inputs, execution conditions, and expected results developed for a particular objective, such as to exercise a particular program path or to verify compliance with a specific requirement. “(2) (IEEE Std 829-1983) Documentation specifying inputs, predicted results, and a set of execution conditions for a test item.” According to Ron Patton (2001, p. 65), “Test cases are the specific inputs that you’ll try and the procedures that you’ll follow when you test the software.” Boris Beizer (1995, p.

  • A Meta-Model for Risk-Based Testing Technique Based on the MDA Approach Atifi Meriem, Marzak Abdelaziz
    International Journal of Scientific & Engineering Research Volume 9, Issue 1, January-2018 429 ISSN 2229-5518 A Meta-Model for Risk-Based Testing Technique Based On the MDA Approach Atifi Meriem, Marzak Abdelaziz Abstract— In software testing area, risk-based testing is a testing technique that uses risk to prioritize and emphasize the appropriate tests during all phases of the test process. By using this technique we can organize testing efforts in a way that reduces the residual level of system risk when it is deployed. From the fact to its high practical relevance, several approaches that support Risk-Based testing technique have been proposed in academic and industrial research. Although, most of these approaches share common principal, common challenges and common characteristic that are inherited from the fundamental concepts of Risk-Based testing technique. In this context, we apply MDA approach to propose in this paper a generic Meta model that represents risk-based-testing elements, concepts, and relationships in order to define the structure and entities that must take any risk-based-testing approach.
