Testing R Code - Richard (datacamp Cotton - Bog - Taylor & Francis Inc - Plusbog.dk

Testing R Code - Richard (datacamp Cotton - Bog - Taylor & Francis Inc - Plusbog.dk

Learn how to write R code with fewer bugs. The problem with programming is that you are always one typo away from writing something silly. Likewise with data analysis, a small mistake in your model can lead to a big mistake in your results. Combining the two disciplines means that it is all too easy for a missed minus sign to generate a false prediction that you don’t spot until it’s too late. Testing is the only way to be sure that your code, and your results, are correct. Testing R Code teaches you how to perform development-time testing using the testthat package, allowing you to ensure that your code works as intended. The book also teaches run-time testing using the assertive package; enabling your users to correctly run your code. After beginning with an introduction to testing in R, the book explores more advanced cases such as integrating tests into R packages; testing code that accesses databases; testing C++ code with Rcpp; and testing graphics. Each topic is explained with real-world examples, and has accompanying exercises for readers to practise their skills — only a small amount of experience with R is needed to get started!

Defending Standardized Testing - - Bog - Taylor & Francis Inc - Plusbog.dk

Defending Standardized Testing - - Bog - Taylor & Francis Inc - Plusbog.dk

The education reform movement of the past two decades has focused on raising academic standards. Some standards advocates attach a testing mechanism to gauge the extent to which high standards are actually accomplished, whereas some critics accuse the push for standards and testing of impeding reform and perpetuating inequality. At the same time, the testing profession has produced advances in the format, accuracy, dependability, and utility of tests. Never before has obtaining such an abundance of accurate and useful information about student learning been possible. Meanwhile, the American public remains steadfast in support of testing to measure student performance and monitor the performance of educational systems.Many educational testing experts who acknowledge the benefits of testing also believe that those benefits have been insufficiently articulated. Although much has been written on standardized testing policy, most of the material has been written by opponents. The contributing authors of this volume are both accomplished researchers and practitioners who are respected and admired worldwide. They bring to the project an abundance of experience working with standardized tests.The goal of Defending Standardized Testing is to:*describe current standardized testing policies and strategies;*explain many of the common criticisms of standardized testing;*document the public support for, and the realized benefits of, standardized testing;*acknowledge the limitations of, and suggest improvements to, testing practices;*provide guidance for structuring and administering large-scale testing programs in light of public preferences and the "No Child Left Behind Act" requirements; and*present a defense of standardized testing and a vision for its future. Defending Standardized Testing minimizes the use of technical jargon so as to appeal to all who have a stake in American educational reform.

How to Reduce the Cost of Software Testing - - Bog - Taylor & Francis Inc - Plusbog.dk

Plenty of software testing books tell you how to test well; this one tells you how to do it while decreasing your testing budget. A series of essays written by some of the leading minds in software testing, How to Reduce the Cost of Software Testing provides tips, tactics, and techniques to help readers accelerate the testing process, improve the performance of the test teams, and lower costs. The distinguished team of contributors—that includes corporate test leaders, best paper authors, and keynote speakers from leading software testing conferences—supply concrete suggestions on how to find cost savings without sacrificing outcome. Detailing strategies that testers can immediately put to use to reduce costs, the book explains how to make testing nimble, how to remove bottlenecks in the testing process, and how to locate and track defects efficiently and effectively. Written in language accessible to non-technical executives, as well as those doing the testing, the book considers the latest advances in test automation, ideology, and technology. Rather than present the perspective of one or two experts in software testing, it supplies the wide-ranging perspectives of a team of experts to help ensure your team can deliver a completed test cycle in less time, with more confidence, and reduced costs.

Testing Complex and Embedded Systems - Kim H. Pries - Bog - Taylor & Francis Inc - Plusbog.dk

Testing Complex and Embedded Systems - Kim H. Pries - Bog - Taylor & Francis Inc - Plusbog.dk

Many enterprises regard system-level testing as the final piece of the development effort, rather than as a tool that should be integrated throughout the development process. As a consequence, test teams often execute critical test plans just before product launch, resulting in much of the corrective work being performed in a rush and at the last minute. Presenting combinatorial approaches for improving test coverage, Testing Complex and Embedded Systems details techniques to help you streamline testing and identify problems before they occur—including turbocharged testing using Six Sigma and exploratory testing methods. Rather than present the continuum of testing for particular products or design attributes, the text focuses on boundary conditions. Examining systems and software testing, it explains how to use simulation and emulation to complement testing. - - Details how to manage multiple test hardware and software deliveries - Examines the contradictory perspectives of testing—including ordered/ random, structured /unstructured, bench/field, and repeatable/non repeatable - Covers essential planning activities prior to testing, how to scope the work, and how to reach a successful conclusion - Explains how to determine when testing is complete - Where you find organizations that are successful at product development, you are likely to find groups that practice disciplined, strategic, and thorough testing. Tapping into the authors’ decades of experience managing test groups in the automotive industry, this book provides the understanding to help ensure your organization joins the likes of these groups.

High-Stakes Testing - R. Murray Thomas - Bog - Taylor & Francis Inc - Plusbog.dk

High-Stakes Testing - R. Murray Thomas - Bog - Taylor & Francis Inc - Plusbog.dk

The federal government''s No Child Left Behind Act has thrust high-stakes testing - its goals, methods, and consequences - into the educational limelight. The four-fold purpose of this book is to: describe the nature of high-stakes testing; identify types of collateral damage that have attended the testing programs; analyze methods different groups of people have chosen for coping with the damage and suggest lessons to be learned from the high-stakes-testing experience. The six groups of people whose coping strategies are inspected include: politicians and their staffs; educational administrators and their staffs; parents and the public; test makers and test administrators; teachers and students. Importantly, the author avoids aligning himself with the test-bashing rhetoric of those who oppose high-stakes testing, especially the No Child Left Behind Act. Key features of this outstanding new book include: - illustrative cases. The book offers more than 350 cases of collateral damage from high-stakes testing--and people''s coping strategies--as reported in newspapers over the 2002-2004 period. - background perspectives. Part I examines the influence of high-stakes testing on: 1) what schools teach; 2) how student progress is evaluated; 3) how achievement standards are set; and 4) how test results are used. - participant responses. Part II, which is the heart of the book, devotes a separate chapter to the coping strategies of each of the major participants in the high-stakes testing movement: politicians and their staffs, educational administrators and their staffs, parents and the public, test-makers and test-givers, teachers, and students. - summary chapter. The last chapter (Lessons to Learn) offers suggestions for minimizing collateral damage by adopting alternative approaches not used in the creation of our current high-stakes testing programs, particularly the federal government''s No Child Left Behind Act. This book is appropriate for any of the following audiences: students taking evaluation or administration courses in schools of education, inservice administrators and teachers, policy makers, and those members of the general public who are concerned about the fate of schooling in America.
