?
This document discusses JavaScript testing using Selenium. It recommends using Selenium 2/WebDriver for JavaScript testing as it allows direct execution of JavaScript commands and assertions of results. The key aspects of JavaScript that should be tested are DOM manipulation, event handling, network calls, and JavaScript code/state. Client-side unit testing frameworks like QUnit can be used with Selenium to execute tests and assert results. Selenium 2 aims to provide a shared browser automation API that allows launching browsers quickly and navigating/executing tests across browsers and versions.Api testing libraries using java script an overview

Service workers allow web applications to work offline by intercepting network requests, caching responses, and serving cached resources when there is no network connection. They also handle background synchronization and push notifications. Key capabilities include making apps available offline, controlling the cache and network requests, and subscribing to push notifications. Service workers operate separately from the main thread of the page, intercepting and modifying fetch events to return cached responses when available.Ajax Presentation

AJAX allows asynchronous data retrieval from a server without page refreshes. It uses XMLHttpRequest objects in JavaScript to make requests to the server and update parts of the page without reloading. Common uses of AJAX include Gmail, Google Maps, and Flickr. It provides a faster and more responsive web experience compared to traditional page loads. Frameworks like AJAX.NET help implement AJAX functionality on both the client-side and server-side.Sanjeev ghai 12

This document provides an overview of ASP.NET AJAX and different approaches to building web applications with it, including server-side ASP.NET, server-side ASP.NET AJAX using UpdatePanels, and client-side ASP.NET AJAX. It discusses features of client-side ASP.NET AJAX like declarative controls, command bubbling, live bindings, and using templates with JSON. It also covers additional ASP.NET AJAX 4.0 features and using data sources like ADO.NET Data Services. The document encourages embracing client-side development for better performance and user experience.Scaling asp.net websites to millions of users

This document discusses various techniques for optimizing ASP.NET applications to scale from thousands to millions of users. It covers topics such as preventing denial of service attacks, optimizing the ASP.NET process model and pipeline, reducing the size of ASP.NET cookies on static content, improving System.net settings, optimizing queries to ASP.NET membership providers, issues with LINQ to SQL, using transaction isolation levels to prevent deadlocks, and employing a content delivery network. The overall message is that ASP.NET requires various "hacks" at the code, database, and configuration levels to scale to support millions of hits.TY.BSc.IT Java QB U4

The document provides answers to multiple questions related to JSP (Java Server Pages). It begins by defining JSP and listing advantages like being HTML friendly and supporting Java code and standard web development tools. It then discusses disadvantages like difficulties tracing errors and requiring more disk space. Subsequent questions and answers cover writing JSP code to display form details, explaining the JDBC and JSP architectures, examples of using prepared statements and implicit objects, and differences between servlets and JSP.Pragmatic Parallels: Java and JavaScript

This document discusses and compares several JavaScript unit testing tools and techniques:
1. JsUnitTest is a simple standalone tool that uses fixtures loaded in the browser but does not scale well and requires browser interaction.
2. BlueRidge is integrated with Rails and easy to set up but runs tests in non-browser environments.
3. JsTestDriver runs tests across multiple actual browsers simultaneously from the command line and scales well but currently lacks support for asynchronous tests.Ajax

This document provides an overview of AJAX (Asynchronous JavaScript and XML) including:
- AJAX allows web pages to be updated asynchronously by exchanging small amounts of data with the server without reloading the whole page.
- The advantages of AJAX include form data validation in real time and partial updates of web content to avoid full page reloads.
- The disadvantages include some search engine indexing issues and a lack of server information access within AJAX.
- AJAX works with browsers using the XMLHttpRequest object to exchange data with servers asynchronously.mukesh

AJAX allows for asynchronous retrieval of data from a web server in the background without interfering with the display and behavior of the existing page. It uses XMLHttpRequest to communicate with web servers asynchronously and update parts of a web page without reloading the entire page. Jesse James Garrett coined the term "AJAX" in 2005 to describe this new technique of using a combination of technologies including XHTML, CSS, JavaScript, DOM, and XMLHttpRequest. Some common uses of AJAX include Google Maps, Gmail, and Flickr to provide dynamic and interactive experiences on the web.More from Kevin Griffin (7)

This document summarizes Kevin Griffin's presentation on using SignalR to build real-time web applications. The presentation covered the history of the web and methods for building real-time applications, introduced SignalR, and demonstrated wiring up a SignalR server and client. Griffin discussed how earlier versions of the web used request/response but real-time applications require continuous connections. He reviewed techniques like polling, long polling, server-sent events and web sockets for real-time functionality and their tradeoffs. SignalR was presented as a solution that supports bi-directional communication and works across browsers.Codemash - Building Custom node.js Modules

Out of the box, ASP.NET can do a lot of amazing things. The tools and framework have grown to make mundane tasks, such as minification, simple to implement. Many times by using the framework as we were taught, opportunities to optimize pass us by. The reality is that underneath the covers, there is a whole world of easy tweaks we can implement to help ASP.NET perform at its peak.
In this presentation, we will walk through a slew of tweaks used to make ASP.NET perform in the best way possible. You will leave with a checklist of tasks that will instantly improve the performance of your web application!Robust Web APIs with node.js and Express
