Team Services, Test Cloud, and HockeyApp

By: Gerald Versluis

Learn everything you need to set up a full-featured, automated pipeline for Xamarin development and deployment. Automate everything from the build step through to deployment and delivery to your customer. If you thought this level of automation could be achieved only by large companies with generous funding, think again! You as a single developer, or working in a small team or company, can automate your processes to punch heavier than your weight. What’s more, you can achieve this level of automation completely for free! This hands-on guide takes you step-by-step from setting up your first automated build all the way to integrated unit testing, and finally through to delivering a high-quality app to your testers and end users. The automation presented in this book saves a lot of frustration and recurring work, providing you more time to focus on building the robust and compelling apps that delight your customers and keep you steps ahead of the competition. Not only does this book teach how to get a grip on consistent quality, but it covers the use of HockeyApp to track events and usage, and to report errors and anomalies back to home base for developers to investigate. Many times it’s possible to detect and fix errors before a user even notices they are there. This book: Teaches the necessity of an automated development pipeline Helps you set up an automated pipeline for Xamarin development Integrates testing (on physical devices!) to ensure high-quality apps What You'll Learn Why you want an automated development pipeline Obtain and configure the automated tooling Continuously integrate your apps Run automated unit tests Push updates to your customers Monitor and detect errors without user intervention Who This Book Is For App developers looking for ways to ensure consistent quality of work and wanting to know how their apps are doing in actual use by customers

Child Welfare for the Twenty-first Century

A Handbook of Practices, Policies, & Programs

By: Gerald P. Mallon,Peg McCartt Hess

The Adoption and Safe Families Act (ASFA), which became law in 1997, elicited a major shift in federal policy and thinking toward child welfare, emphasizing children’s safety, permanency, and well-being over preserving their biological ties at all costs. The first edition of this volume was the earliest major social work textbook to map the field of child welfare after ASFA’s passage, detailing the practices, policies, programs, and research affected by the legislation’s new attitude toward care. This second edition highlights the continuously changing child welfare climate in the U.S., including content on the Fostering Connections Act of 2008. Gerald P. Mallon and Peg McCartt Hess have updated the text throughout, drawing from real world case examples, using data obtained from the national Child and Family Services Reviews and emerging empirically based practices. They have also added chapters addressing child welfare workforce issues, supervision, and research and evaluation. Divided into four sections—child and adolescent well-being, child and adolescent safety, permanency for children and adolescents, and systemic issues within services, policies, and programs—this newly edited volume provides a current understanding of family support and child protective services, risk assessment, substance and sexual abuse issues, domestic violence issues, guardianship, reunification, kinship and foster family care, adoption, and transitional living programs. Recognized scholars, practitioners, and policy makers also discuss meaningful engagement with families, particularly Latino families; health care for children and youth, including mental health care; effective practices with LGBT youth and their families; placement stability; foster parent recruitment and retention; and the challenges of working with immigrant children, youth, and families.
