On fx jsj unit - an idea to test javascript codes with junit and javafxShinya Mochida This document introduces FxJsJUnit, a library for testing JavaScript code with JUnit using JavaFX's WebEngine. It is written by Mike Neck, who is interested in concurrent programming. FxJsJUnit allows testing JavaScript with type-safe assertions in JUnit. It uses a JavaFX WebEngine as the JavaScript environment. Sample code is provided to demonstrate preparing tests, accessing the WebEngine, and calling JavaScript from tests. Issues like embedding web servers and concurrent test execution are mentioned as topics for future work.
Java
JavaSangeethaSasi1 This document discusses exception handling in Java. It defines that exceptions are objects describing error conditions that occur during code execution. There are two main branches of exceptions - those headed by Exception which are intended to be caught by programs, and Errors headed by the Error class which indicate runtime environment issues. The document provides details on try/catch blocks for handling exceptions, built-in exception types like RuntimeException, and how to throw exceptions manually using the throw keyword. It includes an example program demonstrating catching and rethrowing an exception.

Integrating grunt and bower with maven
Integrating grunt and bower with mavenRahul Nanwani This document discusses integrating front-end tools like Grunt and Bower with build tools like Maven to improve the front-end development workflow for Java web apps. It outlines how Maven currently uses plugins like wro4j for tasks like JavaScript minification and CSS compilation. Grunt and Bower are proposed as alternatives that offer more tasks and easier setup than wro4j. Integrating Grunt and Bower through shell commands makes them extensible to work with various build tools like Maven. Example setup and code for both development and production environments using Maven will be shared.

By 2015, global mobile data traffic will increase 26-fold from 2010 levels and two-thirds of mobile data traffic will be from video. There will also be 788 million mobile-only internet users by 2015. Tablets are contributing significantly to this growth, with each tablet generating 5 times more data traffic than the average smartphone in 2010. Mobile constraints require web designers to focus on creating content that is focused, fast and frequently used on small screens.
Maven overview
Maven overviewSamuel Langlois Maven is a build automation tool used primarily for Java projects that utilizes a project object model (POM) to manage dependencies and build processes. It was created in 2001 to standardize builds of Apache projects. Some key features include dependency management, a standard project layout, configurable build lifecycles and phases, and plugins for tasks like compiling, testing, packaging, and reporting. Maven aims to provide a uniform build system and is not intended to replace build tools like Ant.

Conceptual Application Project-Ginny Flannery
Conceptual Application Project-Ginny FlanneryGinnyFlannery The document discusses the High Interest, High Achievement Theory, which states that students will achieve higher on projects and papers that they are interested in compared to ones they have no interest in. It provides the author's personal experience struggling in classes she wasn't interested in as evidence for developing this theory. The theory is considered interpretive as the truth is socially constructed and can have multiple meanings and interpretations depending on the individual. The theory focuses on conscious choices made by students and how interest levels affect achievement outcomes rather than aiming to prove an absolute truth. Real-life applications include examining interest levels and past achievement, applying the concept to career motivation, and looking at hobbies and interests.

Easymock Tutorial
Easymock TutorialSbin m Mocking allows you to test classes and methods in isolation by replacing their collaborators with mock objects that simulate the normal environment. EasyMock is a framework for creating mock objects that uses a record/replay approach where you first define the expected behavior of mock objects and then replay the code under test to verify it behaves as expected. Mock objects can be normal, strict, or nice depending on how strictly they enforce the expected behavior and order of method calls.

JMockit Framework Overview
JMockit Framework OverviewMario Peshev JMockit is a Java mocking framework that provides tools for isolating code dependencies during unit testing. It uses bytecode instrumentation to remap classes at runtime, allowing final classes and static methods to be mocked. Expectations define mock object behavior, and verifications ensure mocks are used as expected. JMockit provides a more powerful and flexible mocking approach than alternatives like Mockito through its instrumentation and expectations/verifications APIs.
Mocking in Java with Mockito
Mocking in Java with MockitoRichard Paul Mockito is a mocking framework for Java that allows developers to focus tests on interactions between objects rather than states. It provides test doubles like mocks and spies to simulate dependencies and verify expected interactions. Mockito allows mocking method calls and configuring return values or exceptions to test different scenarios. It provides default values for unstubbed calls to avoid overspecifying tests.

Unit testing basic
Unit testing basicYuri Anischenko Unit testing involves writing individual units of code to determine if they are functioning properly, where a unit is the smallest testable part like a method or class; it ensures code is properly designed and functions as intended when client uses the interface, but should not rely on external resources or other subsystems to avoid integration testing. Unit testing finds bugs early, allows for safe refactoring, and improves code quality and developer focus through documentation and feedback from running tests automatically.
