Reactive Programming (RP) is critical to many concurrent platforms. It endeavors to make the method of constructing highly-concurrent, event-driven, and asynchronous purposes less complicated and not more error-prone. RP is available in many flavors and we'll examine a few of them during this book.
Clojure Reactive Programming is a realistic consultant geared toward exploring RP. It begins by means of describing sensible Reactive Programming (FRP) and its formulations, in addition to the way it encouraged Compositional occasion structures (CES).

It additionally offers numerous examples of Reactive purposes applied in several frameworks, permitting you to improve an realizing of the topic in addition to advance your skill to paintings with time-varying values.

By the top of the publication, you can be outfitted to unravel real-world difficulties in addition to comprehend the trade-offs among the methods proven within the publication

Summary

Specification through instance is an rising perform for growing software program in accordance with real looking examples, bridging the conversation hole among enterprise stakeholders and the dev groups construction the software program. during this booklet, writer Gojko Adzic distills interviews with profitable groups world wide, sharing how they specify, boost, and carry software program, with no defects, briefly iterative supply cycles.
concerning the Technology
Specification through instance is a collaborative strategy for specifying requisites and checks. Seven styles, totally explored during this ebook, are secret to meaking the strategy potent. the strategy has 4 major merits: it produces residing, trustworthy documentation; it defines expectancies essentially and makes validation effective; it reduces transform; and, particularly, it assures supply groups and enterprise stakeholders that the software program that's outfitted is true for its purpose.
concerning the Book
This publication distills from the adventure of major groups around the globe potent how you can specify, attempt, and convey software program in brief, iterative supply cycles. Case stories during this ebook variety from small internet startups to giant monetary associations, operating in lots of techniques together with XP, Scrum, and Kanban.

This booklet is written for builders, testers, analysts, and company humans operating jointly to construct nice software.

Paul Hamill's Unit Test Frameworks: Tools for High-Quality Software PDF

Put up 12 months observe: First released in 2004
------------------------

Unit try out frameworks are a key component of well known improvement methodologies equivalent to severe Programming (XP) and Agile improvement. yet unit trying out has moved a long way past severe Programming; it's now universal in lots of sorts of software improvement. Unit checks support be sure low-level code correctness, lessen software program improvement cycle time, enhance developer productiveness, and convey extra powerful software.

Until now, there has been little documentation to be had on unit trying out, and such a lot resources addressed particular frameworks and particular languages, instead of explaining using unit trying out as a language-independent, standalone improvement method. This priceless new e-book covers the idea and heritage of unit try frameworks, bargains step by step guide in uncomplicated unit try out improvement, presents invaluable code examples in either Java and C++, and comprises information on probably the most typical frameworks this day from the XUnit relations, together with JUnit for Java, CppUnit for C++, and NUnit for . NET.

Unit try Frameworks comprises transparent, concise, and targeted descriptions of: the speculation and layout of unit try out frameworks Examples of unit exams and frameworks types of unit assessments well known unit try out frameworks And extra it is usually the full resource code for CppUnit for C++, and NUnit for . web.

Example text

In Clojure, a simple version of the Observer pattern can be implemented using watches: (def numbers (atom [])) (defn adder [key ref old-state new-state] (print "Current sum is " (reduce + new-state))) (add-watch numbers :adder adder) We start by creating our program state, in this case an atom holding an empty vector. Next, we create a watch function that knows how to sum all numbers in numbers. Finally, we add our watch function to the numbers atom under the :adder key (useful for removing watches).

When the observable changes, it pushes its changes to the observer synchronously. ) (reduce +)) This time around, the vector is the subject being observed and the functions processing it can be thought of as the observers. However, this works in a pull-based model. The vector doesn't push any elements down the sequence. Instead, map and friends ask the sequence for more elements. This is a synchronous operation. Rx makes sequences—and more—behave like observables so that you can still map, ilter, and compose them just as you would compose functions over normal sequences.

Main-frame :content price-label) As you can see, the UI is fairly simple. It consists of a single label that will display a company's share price. We also imported two Java classes, ScheduledThreadPoolExecutor and TimeUnit, which we will use shortly. The next thing we need is our polling machinery so that we can invoke the pricing service on a given schedule. We'll implement this via a thread pool so as not to block the main thread: User interface SDKs such as swing have the concept of a main—or UI—thread.
