The document provides tips for adding testing to JavaScript projects. It recommends choosing a testing environment and dialect, then setting up the tests by installing dependencies and configuring files. Common issues like testing asynchronous code and methods that call other methods can be addressed with spies, stubs, mocks and promises. Tests should focus on isolated units of code and avoid direct DOM manipulation when possible. Automating testing through build tools like Grunt and Testem helps to easily run and watch tests. Overall, the document emphasizes making testing easy by writing maintainable, modular code and setting up automation.

OVERVIEW
AngularJS is an open-source JavaScript framework, maintained by Google, that simplifies development of single-page applications. This session will provide an overview of AngularJS framework and demonstrate test-driven development of single-page applications.
In this session Andy will present a walkthrough of Angular’s core features such as dependency injector and directives. He will showcase a test-driven development of AngularJS applications using Jasmine and explain Angular’s data bindings that allow for creation of views and controllers that update automatically in response to data changes. He will also demo Angular’s deep linking and front-end validations and present integration with Ruby On Rails back end using AngularJS AJAX abstractions. Finally, Andy will utilize AngularJS directives and components to create reusable UI elements.
In summary, AngularJS is a great framework for creating complex single-page applications. Attendees will leave the talk with a solid understanding of Angular’s test-driven development process.
This presentation deals with a complex approach to application testing in back end and front end parts, tests writing and common mistakes. It also includes a short overview of libraries and frameworks for creation of tests, as well as practical examples of code.
Presentation by Pavlo Iuriichuk, Lead Software Engineer, GlobalLogic, Kyiv), delivered at an open techtalk on December 11, 2014.

* Mocking and spy techniques to avoid dependencies on
- Functions, methods and constructor functions
- Time (new Date())
- Timers (setTimeout, setInterval)
- Ajax requests
- The DOM
- Events
* Expressive matchers
- Jasmine-jQuery
* Structuring tests for reuse and readability
* Testing browser-specific behaviour

V1.0
How often do you get a bug report that you can’t reproduce?
How often do you struggle to find the source of the bug in your code?
How can you streamline the testing process and make sure you don’t repeat the same bugs?
With Visual Studio 2010 & Team Foundation Server (TFS) 2010 there are a lot of new features for testers and developers that will solve these problems.
In this session you will learn how to: automate more, reproduce bugs easier, maintain your tests and configuration and discover problems sooner.

Unit Testing Front End JavaScript
with Yuri Takhteyev
Presented on September 18 2014 at
FITC's Web Unleashed Toronto 2014 Conference
More info at www.fitc.ca
Building complex software application can be made much easier with unit testing – a fact well established in back-end work but often overlooked on the front-end. Yuri Takhteyev will look at some of the tools and techniques for unit testing front end code, focusing on Mocha and Karma. Most of the examples will draw on AngularJS but the main ideas are applicable to other frameworks as well.
OBJECTIVE
Learn how to write unit tests for front-end code.
TARGET AUDIENCE
Front-end JavaScript developers not currently using unit testing or those experiencing difficulties with unit testing.
ASSUMED AUDIENCE KNOWLEDGE
Intermediate front-end JavaScript, no prior experience with front-end unit testing
FIVE THINGS AUDIENCE MEMBERS WILL LEARN
How unit testing benefits the developer
How to structure applications to make them testable
How to use Mocha and Karma in unit testing
How to mock dependencies (and why)
How to handle asynchronous code
JavaScript Fundamentals with Angular and LodashBret Little
The purpose of this presentation is also largely to explain some of the fun parts of JavaScript (dynamic function invocation with reflection, dynamic arguments, etc). I don't necessarily encourage putting complex logic throughout your templates with lodash, though there may be times it is appropriate.
Lets talk about lodash and how it can easily be married to Angular. Using a six line filter, I will expose the power of lodash directly within angular templates. This will be an introduction to lodash, angular templates, and we'll talk about scope and reflection within JavaScript.
Silex is a brand new PHP 5.3 micro framework built on top of the Symfony2 de decoupled components. In this session, we will discover how to build and deploy powerful REST web services with such a micro framework and its embedded tools.
The first part of this talk will introduce the basics of the REST architecture. We fill focus on the main concepts of REST like HTTP methods, URIs and open formats like XML and JSON.
Then, we will discover how to deploy REST services using most of interesting Silex tools like database abstraction layer, template engine and input validation. We will also look at unit and functional testing frameworks with PHPUnit and HTTP caching with Edge Side Includes and Varnish support to improve performances.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
