Dr. C#: a Pedagogic IDE for C# Featuring a Read-Eval-Print-Loop by Dennis Lu
RICE UNIVERSITY Dr. C#: A Pedagogic IDE for C# Featuring a Read-Eval-Print-Loop by Dennis Lu ATHESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE Master of Science APPROVED,THESIS COMMITTEE: Robert Cartwright, Chair Professor of Computer Science Joe Warren Professor of Computer Science Dan Wallach Assistant Professor of Computer Science Dung X. Nguyen Lecturer, Computer Science Houston, Texas April, 2003 Dr. C#: A Pedagogic IDE for C# Featuring a Read-Eval-Print-Loop Dennis Lu Abstract As the primary programming language of the Microsoft .NET platform, C# will play a significant role in software development for the foreseeable future. As the language rapidly gains popularity in industry, tools made for C# development fo- cus on the professional programmer, while leaving the beginning computer science student behind. To address this problem, we introduce Dr. C#, a simple lightweight develop- ment environment with an integrated, interactive Read-Eval-Print-Loop (REPL). Dr. C# helps flatten the learning curve of both the environment and the language, enabling students to quickly learn key elements of the language and focus more easily on concepts. Dr. C# thus serves not only as a learning tool for beginner students but also as a teaching tool for instructors. The editor is based on an open source IDE called SharpDevelop. This thesis describes the implementation of Dr. C# focusing primarily on building the REPL and integrating with SharpDevelop. Acknowledgments I would like to thank my advisor Professor Robert “Corky” Cartwright for giving me the opportunity and autonomy to develop Dr. C#. I would also like to thank Professor Dung Nguyen for acting as co-advisor and for his years of guidance and support. -

Mannheim, 16.03.2010 ________________________ Unterschrift I Refactoring of Acceptance Tests in Visual Studio ABSTRACT Executable Acceptance Test Driven Development (EATDD) is an extension of Test Driven Development (TDD). TDD requires that unit tests are written before any code. EATDD pushes this TDD paradigm to the customer level by using Acceptance Tests to specify the requirements and features of a system. The Acceptance Tests are mapped to a Fixture that permits the automated execution of the tests. With ongoing development the requirements of the system can change. Thus, the Acceptance Tests must be adjusted in order to reflect the new requirements. Since the tests and the corresponding Fixtures must remain consistent, the manual modification of these tests is time consuming and error-prone. Hence comes the need for Acceptance Test refactoring. -

Chapter 8 Automation Using Powershell
Chapter 8 Automation Using PowerShell Virtual Machine Manager is one of the first Microsoft software products to fully adopt Windows PowerShell and offer its users a complete management interface tailored for script- ing. From the first release of VMM 2007, the Virtual Machine Manager Administrator Console was written on top of Windows PowerShell, utilizing the many cmdlets that VMM offers. This approach made VMM very extensible and partner friendly and allows customers to accomplish anything that VMM offers in the Administrator Console via scripts and automation. Windows PowerShell is also the only public application programming interface (API) that VMM offers, giving both developers and administrators a single point of reference for managing VMM. Writing scripts that interface with VMM, Hyper-V, or Virtual Server can be made very easy using Windows PowerShell’s support for WMI, .NET, and COM. In this chapter, you will learn to: ◆ Describe the main benefits that PowerShell offers for VMM ◆ Use the VMM PowerShell cmdlets ◆ Create scheduled PowerShell scripts VMM and Windows PowerShell System Center Virtual Machine Manager (VMM) 2007, the first release of VMM, was one of the first products to develop its entire graphical user interface (the VMM Administrator Con- sole) on top of Windows PowerShell (previously known as Monad). This approach proved very advantageous for customers that wanted all of the VMM functionality to be available through some form of an API. The VMM team made early bets on Windows PowerShell as its public management interface, and they have not been disappointed with the results. With its consis- tent grammar, the great integration with .NET, and the abundance of cmdlets, PowerShell is quickly becoming the management interface of choice for enterprise applications. -

Pyref: a Refactoring Detection Tool for Python Projects
Università Software della Institute Svizzera italiana PYREF:AREFACTORING DETECTION TOOL FOR PYTHON PROJECTS Hassan Atwi June 2021 Supervised by Prof. Dr. Michele Lanza Co-Supervised by Dr. Bin Lin SOFTWARE &DATA ENGINEERING MASTER THESIS iii Abstract Refactoring, the process of improving internal code structure of a software system without altering its external behav- iors, is widely applied during software development. Understanding how developers refactor source code can help us gain better understandings of the software development process and the relationship between various versions of software systems. Currently, many refactoring detection tools (e.g., REFACTORINGMINER and REF-FINDER) have been proposed and have received considerable attention. However, most of these tools focus on Java program, and are not able to detect refactorings applied throughout the history of a Python project, although the popularity of Python is rapidly magnifying. Developing a refactoring detection tool for Python projects would fill this gap and help extend the language boundary of the analysis in variant software engineering tasks. In this work, we present PYREF, a tool that automatically detect 11 different types of refactoring operations in Python projects. Our tool is inspired by REFACTORING MINER, the state-of-the-art refactoring detection tool for Java projects. With that said, while our core algorithms and heuristics largely inherit those of REFACTORING MINER, considerable changes are made due to the different language characteristics between Python and Java. PYREF is evaluated against oracles collected from various online resources. Meanwhile, we also examine the reliability of PYREF by manually inspecting the detected refactorings from real Python projects. Our results indi- cate that PYREF can achieve satisfactory precision. -
Introduction to Unit Testing
INTRODUCTION TO UNIT TESTING In C#, you can think of a unit as a method. You thus write a unit test by writing something that tests a method. For example, let’s say that we had the aforementioned Calculator class and that it contained an Add(int, int) method. Let’s say that you want to write some code to test that method. public class CalculatorTester { public void TestAdd() { var calculator = new Calculator(); if (calculator.Add(2, 2) == 4) Console.WriteLine("Success"); else Console.WriteLine("Failure"); } } Let’s take a look now at what some code written for an actual unit test framework (MS Test) looks like. [TestClass] public class CalculatorTests { [TestMethod] public void TestMethod1() { var calculator = new Calculator(); Assert.AreEqual(4, calculator.Add(2, 2)); } } Notice the attributes, TestClass and TestMethod. Those exist simply to tell the unit test framework to pay attention to them when executing the unit test suite. When you want to get results, you invoke the unit test runner, and it executes all methods decorated like this, compiling the results into a visually pleasing report that you can view. Let’s take a look at your top 3 unit test framework options for C#. MSTest/Visual Studio MSTest was actually the name of a command line tool for executing tests, MSTest ships with Visual Studio, so you have it right out of the box, in your IDE, without doing anything. With MSTest, getting that setup is as easy as File->New Project. Then, when you write a test, you can right click on it and execute, having your result displayed in the IDE One of the most frequent knocks on MSTest is that of performance. -

How Does Object-Oriented Code Refactoring Influence
How does Object-Oriented Code Refactoring Influence Software Quality? Research Landscape and Challenges Satnam Kaur *1, Paramvir Singh2 1Department of Computer Science and Engineering Dr B R Ambedkar National Institute of Technology, Jalandhar 144011, Punjab, India 2 School of Computer Science University of Auckland, Auckland 1142, New Zealand ABSTRACT Context: Software refactoring aims to improve software quality and developer productivity. Numerous empirical studies investigating the impact of refactoring activities on software quality have been conducted over the last two decades. Objective: This study aims to perform a comprehensive systematic mapping study of existing empirical studies on evaluation of the effect of object-oriented code refactoring activities on software quality attributes. Method: We followed a multi-stage scrutinizing process to select 142 primary studies published till December 2017. The selected primary studies were further classified based on several aspects to answer the research questions defined for this work. In addition, we applied vote-counting approach to combine the empirical results and their analysis reported in primary studies. Results: The findings indicate that studies conducted in academic settings found more positive impact of refactoring on software quality than studies performed in industries. In general, refactoring activities caused all quality attributes to improve or degrade except for cohesion, complexity, inheritance, fault-proneness and power consumption attributes. Furthermore, individual refactoring activities have variable effects on most quality attributes explored in primary studies, indicating that refactoring does not always improve all quality attributes. Conclusions: This study points out several open issues which require further investigation, e.g., lack of industrial validation, lesser coverage of refactoring activities, limited tool support, etc.
