Functional Python Programming, 3rd edition
Not enough developers understand the benefits of functional programming, or even what it is. Author Steven Lott demystifies the approach, teaching you how to improve the way you code in Python and make gains in memory use and performance. If you’re a leetcoder preparing for coding interviews, this book is for you.Starting from the fundamentals, this book shows you how to apply functional thinking and techniques in a range of scenarios, with Python 3.10+ examples focused on mathematical and statistical algorithms, data cleaning, and exploratory data analysis. You'll learn how to use generator expressions, list comprehensions, and decorators to your advantage. You don't have to abandon object-oriented design completely, though – you'll also see how Python's native object orientation is used in conjunction with functional programming techniques.By the end of this book, you'll be well-versed in the essential functional programming features of Python and understand why and when functional thinking helps. You'll also have all the tools you need to pursue any additional functional topics that are not part of the Python language.

Technology was changing fast and Gunnard rode the wave from 1200 to 56k baud modems. Logging in to BBSs, Prodigy, Compuserve, Delphi and IRC he could see the world changing and he wanted to be a part of it. He soon got involved in the ansi/demo scene, making several application generators for many groups in the 90’s. Visual Basic was the next language of choice allowing him to develop “tools” for online systems such as AOL. This introduced many aspects of development, security and UI while they were still in their infancy. Once the WWW arrived via Mindspring in Atlanta, Ga. Gunnard quickly joined in the race for the web. Learning HTML, PERL and Linux (Slackware at the time) he began to build his skill-set which lead to a full-time Sysadmin position at the age of 20 (2000) at Activegrams/Silverpop. Gunnard has moved around the IT industry from SAN/NAS storage at IBM to custom Wordpress sites for marketing companies, but one thing has stayed the same, a passion for learning and problem solving. Gunnard also DJ’s Drum and Bass as Section31, Playing drums and baking bread.SATEJ KUMAR SAHU works in the role of Senior Enterprise Architect at Honeywell.

Boozang from the Trenches
Test Automation is a key aspect of delivering high-quality software and reducing time to market. Several tools and approaches are available today, each with its own constraints and specificity. This book introduces Boozang, a codeless web automation tool, using a real-life enterprise project as source for examples.You'll have the opportunity to learn the basic features of Boozang and how to implement end-to-end automated scenarios, mixing GUI and API actions. Integration with JIRA-XRay and Jenkins is also covered to show how Boozang can be used effectively in an enterprise environment. The book is filled with examples that go beyond the Boozang tool, and cover the setup of a test automation project in a real context, with practical solutions as well as open points for which we are still looking for new ideas.YOU WILL LEARN HOW TO:· Install and set up a project with Boozang· Create a modular test suite and use Gherkin to define scenarios· Integrate Boozang with JIRA-XRay and work in a team with code branches· Build a Jenkins pipeline to execute the automated scenarios nightly and reduce the execution time via parallelismTHIS BOOK IS FOR:Testers and test managers, IT projects leads, Release and Delivery Managers, Developers, and Business AnalystsGianni is a simple guy from Livorno (a beautiful port city in Tuscany) who never thought he would end up with a Ph.D. at CERN (European Organization for Nuclear Research, cern.ch) and then working for a prestigious company in Switzerland. But he always knew that at some point in his life, he would have written a book.In his early career as a software developer, he built some C/C++ code but, pretty soon, debugging null pointer exceptions drove him crazy. He then decided he would be better off testing software rather than building it.Wherever he worked, he tried to push for automating tests. Because manual testing, let’s be honest, is not fun, and it can be dangerously repetitive. People at work must have fun, if possible. At Touring Club Suisse, he defined an IT Test Strategy stating “Test automation is developers’ stuff” until he discovered Boozang. And then, in his first two hours of using this tool, he thought, “Man, this is fun!”.Thus, he finally found a good topic for his book.Part 1: Testing web applications in an Enterprise context, why Boozang Chapter 1: Web Test Automation in an Enterprise environmentCHAPTER GOAL: This chapter introduces basic Test Automation concepts that will be used throughout the book. Besides ISTQB standard terminology, I’ll also cover the constraints typical of an Enterprise environment that might not be the same for small startups and IT giants.NO OF PAGES 15SUB -TOPICS1. Common Test Automation challenges2. Test levels, test types and testing roles3. Test automation in agile development4. Test Automation ROI, theory and practiceChapter 2: Selenium, best practices and pain pointsCHAPTER GOAL: This chapter presents the typical approach to testing web applications with coded solutions like Selenium and highlights the main pain points that could undermine a Test Automation initiative's success.NO OF PAGES: 5SUB - TOPICS1. Locators and Page Objects pattern2. Browsers and WebDriver compatibility3. Timing and waits4. Data management5. Reporting and script readability6. Development skillsChapter 3: Meet BoozangCHAPTER GOAL: This chapter introduces Boozang and how it addresses the pain points of a coded solution as described in the previous chapter. It also presents a possible selection approach for selecting an automation tool, particularly the one I followed before adopting Boozang.NO OF PAGES : 11SUB - TOPICS:1. Proof of Concept phase2. Pilot phase3. Why Boozang4. Codeless approach, how important is it?Chapter 4: The TCS projectCHAPTER GOAL: This chapter presents the context of the TCS project used all along the book to provide practical examples. I believe that there is no one size fits all solution for software testing and tools. Therefore, clarifying the context is very important to better understand the examples and consider possible adaptations one will have to make for a different context.NO OF PAGES: 8SUB - TOPICS:1. TCS Organization and Test Automation history2. NIS project introduction3. Test automation stream, NISTA setupChapter 5: How Boozang was bornCHAPTER GOAL: This chapter is a special one about the history behind Boozang. I believe it gives a great idea about this tool's strengths: the two key persons behind it. This input has been kindly provided by Mats Ljunggren.PART 2: Boozang main concepts and use cases Chapter 6: Starting up with BoozangCHAPTER GOAL: One of the advantages of a tool like Boozang versus a coded approach is that setting up your first projects is really easy and fast. Nothing to install, no code or POM files to prepare. This chapter will go over the registration process and the few steps needed to create a project. We will also see how to administer your account and projects and finally show how Boozang works behind the scenes.NO OF PAGES: 22SUB - TOPICS:1. Creating your first project2. The administrative User Interface3. Boozang under the hood4. Practice: NISTA setup part 1Chapter 7: Main concepts and entitiesCHAPTER GOAL: This chapter describes the core objects available in Boozang and starts introducing the Integrated Development Environment (IDE).NO OF PAGES: 38SUB - TOPICS:1.

Updates from the trenchesChapter 8: Elements location approachCHAPTER GOAL: This chapter describes Boozang’s unique approach for locating WEB GUI elements, one of the features that sets it apart from other tools. Boozang, with its set of locators based on natural language, allows you to focus on the scenario flow rather than the web page DOM.NO OF PAGES: 14SUB - TOPICS:1. Boozang location strategy2. Fine tuning the locators3. Validating the expected resultsChapter 9: Exit conditions, conditional flows, and timersCHAPTER GOAL: The first test you will try with Boozang will be a simple sequential list of actions. But, as soon as you start implementing real scenarios, you will have to use exit conditions, loops, and conditional flows. In combination with this, you may need to adjust the timing of some locators, as some applications may have slow background processes, heavy loading pages, and/or javascripts. In this chapter, we see how to apply these concepts to build solid and reusable building blocks.NO OF PAGES: 21SUB - TOPICS:1. Exit conditions2. Conditional flows3. Loop groups4. TimersChapter 10: Data ManagementCHAPTER GOAL: This is probably one of the most important chapters, as data management is one of the main keys to build reusable components. Boozang is extremely powerful and flexible when it comes to managing test data. But power and flexibility can hide a complexity cost if you don’t use it properly.NO OF PAGES: 13SUB - TOPICS:1. Data management concepts2. Parameters3. Project data ($project)4. Module data ($module)5. Test data ($test)6. Loops ($loop, $group, $action)7.
