Selenium Test Package

Selenium is a package of various test components which consists of the following three major tools. Each one has a specific role in aiding the development of test automation for a Web application.

1. Selenium IDE – A Firefox extension to record test cases and suites.
2. Selenium RC – Used to run tests on different browsers and systems.
3. Selenium Grid – Runs multiple instances of Selenium RC at once.
4. Quality and Tellurium – A wrapper for the Selenium engine.

Selenium Modes:

Bases on the components Selenium has following three modes for executing the test cases and test suites:

• Record-Playback mode (Selenium IDE)‏:

In this mode only Selenium IDE is used to record the test scenarios in terms of test cases in firefox. This is a great way to get started to writing tests and group them together to form the test suite. The recorded tests can be exported to many programming languages so that we can tweak them and put them in the testing framework. The test cases and test suites can be replayed back to check the verifications and validations or sent to Selenium RC or Grid for further tweaking.

• Selenium Remote Control (RC) Mode

In this mode Selenium starts multiple browsers (one at a time) and then runs the recorded test-cases which are saved in your language of choice. This helps to enhance the test cases with looping and programming techniques to cover all the required test scenarios and checks.

• Test Runner Mode

In this mode the test cases are recorded ad replayed in the form of HTML tables. This is just one more facility to execute the Selenium IDE as well as RC test cases. This helps to check the test results reports in better manner if not formatted already.

Testing AJAX with Selenium

Selenium IDE – Recording and updating a script

Selenium IDE is the FireFox Add-on provided by the Selenium group. This is very simple and easy to use add-on so that non-programmers can record and create the test scripts for automating web components. These automated test scripts are used as Selenium RC test cases by choosing the language code. i.e. Selenium IDE makes easier to create Selenium RC test cases. (Install Selenium IDE and Selenium RC from Selenium download page).

Selenium IDE is used for:

• Recording and updating the test cases or write them manually in table tab.
• Creating Test Suite by grouping the test cases under one group
• Exporting Test Cases/Suites the supported language and save for Selenium RC to enhance them
• Finding reference of every API and Selense commands
• Debugging test cases by toggling breakpoints through the commands

Selenium IDE – Most commonly used commands

The following are the most commonly used commands in the Selenium IDE:

open: Opens a page using a URL.

click: Clicks the element/object on the page.

clickAndWait: Performs a click operation, and optionally waits for a new page to load.

verifyTitle: Verifies the expected title and continues to run if it fails.

assertTitle: Verifies an expected page title and stops the execution if it fails.

verifyTextPresent: Verifies that the expected text is present somewhere on the page.

verifyElementPresent: Verifies an expected UI element, as defined by its HTML tag.

verifyText: Verifies that the expected text and its corresponding HTML tag are present on the page.

waitForPageToLoad: Pauses execution until an expected new page loads.

waitForElementPresent:Pauses execution until an expected UI element, as defined by its HTML tag, is present on the page. Used with AJAX calls.

Android Training in chennai

What is Android?

 

Android is a Linux-based, open-source operating system designed for use on cell phones, e-readers, tablet PCs, and other mobile devices. For users of smart phones, Android provides simple access to social networking sites like Facebook, Twitter, and YouTube and smooth integration with Google product like Gmail, Google Maps, and Google Calendar. While it is closely-held by Google, it should not be confused with Google’s Chrome OS, a web-resident, thin-client operating system designed primarily for netbooks and tablets rather than for mobile devices. Android has been adopted by a number of makers, including Motorola, Samsung, HTC, and Sony Ericsson. The expanding assortment of applications available on this platform suggests that Android-based phones cancontinue to be strong competitors within the smart-phone market.

How will it work?

As a mobile platform, Android has fully grown in quality among hardware manufacturers and the general public alike in recent years. Its open market model allows registered software system developers to create applications for automaton mobile devices in Java and list them in Android Market while not undergoing review and waiting for approval. Users can transfer from a growing store of smart-phone applications at Google Market, many of that connect with existing Google services. They can additionally transfer compatible Android apps from different locations. Flexible and all-mains, Android’s facility in supporting screen-based interfaces has also made it the OS of alternative for several industrial and shopper electronics, including navigation devices, set-top boxes, kiosks, self checkout stands, medical equipment, netbooks, tablets, and e-readers.

Who’s doing it?

Computer science departments at various schools and universities are clench development for the automaton platform. A grant from Qualcomm and Vodafone this year, for example, funded a student contest for the best learning-focused application designed on the Android platform at the University of Illinois at Urbana Champaign. Engineering doctoral students from the University of Washington work at Google’s Data Kit that they created. This free data-collection platform, built on Android, is designed to be used with mobile devices within the developing world, where information assortment instrumentality is in short provide and is often too expensive for sensible use. In Europe, a student team at the University of Applied Sciences, Northwest Switzerland, wrote a technical report called “Using automaton in Industrial Automation,”

Android and explains its use in mobile technology.Why is it significant?

As a free mobile OS, Android has been elite by several hardware manufacturers to run on a wide vary of devices, include ing cell phones, tablets, e-readers, net books, and others. Android based phones area unit obtainable from all major cellular suppliers in the U.S. market, meaning that most students will choose a phone running Android from the marketer their friends or families already use. Consequently, Android could bring sensible phone and pill functionality to a much wider crosswise of scholars and school members. Like the iPhone, an automaton device could possibilities with regard to context awareness. Android phones can be established to acknowledge once the phone operator is in a very automobile, causing the device to respond by reading text messages aloud and accepting solely voice input. Or cell phones could silence automatically during category time if users’ calendars embrace category schedules. Such location-awareness could see use in campus-based learning activities like augmented reality games or may prompt a student in the library pursuing Associate in Nursing English assignment that a previously requested physics text is currently obtainable for checkout. 

What are the downsides?

 

Platform fragmentation is an issue for automaton OS devices. Vendors do not have uniform policies with relevancy OS upgrades and version control, so new application releases could not work reliably across all automaton devices. Further, while the variety of applications available for automaton is growing, it continues to trail the number obtainable from the iTunes store. Fewer applications could mean less flexibility for students WHO want to utilize automaton devices in their schoolwork. For developers, the variety of device types and type factors that use automaton create development additional expensive; they must adapt their applications to a range of screen sizes and manufacturer specifications, test the results on each applicable device, and ensure compatibility and functionality across the board. As a result, users may find Associate in Nursing application does not operate precisely the same manner on all automaton phones and may gift deferent variations when put next to its iOS equivalent iPhone/Android environment. Finally, Android applications could pose some privacy or security considerations as a result of, unlike Apple, Google does not administer or approve third-party automaton apps before they go to promote. For example, in a joint study by Duke University, Penn State University, and Intel, researchers studied a random selection of free automaton applications and found that  of them sent private info together with GPS coordinates and phone numbers to remote servers without seeking permission or notifying users. 

Where is it going?

 

The Android OS could accelerate the discussion of sensible phones by providing a free operating system that may draw from more than one hundred,000 applications, including those that support teaching and learning. Access to the Android software system development kit (SDK) suggests that the number of applications can continue to swell as professional developers offer new options. In addition, the App Inventor, which provides a web-based visual development environment for those new to this type of programming, is meant to entice students and developers from outside the computer science department to write their own applications and thereby ensure a growing base of apps going forward. If App Inventor proves simple enough for non-developers to use, faculty  members and students alike may build custom automaton applications for research comes, learning challenges, and classroom use. This could have interaction student interest within the work they are doing and additionally in the tools they use, thereby transforming them from customers of existing applications to creators of apps designed to meet their needs. 

What are the implications for teaching and learning?

The popularity of sensible phones among customers suggests that developers must assess the spectrum of operational systems upon that these devices run and determine wherever their e orts can be best spent. Android and iOS, being the two biggest players during this market, will continue to o er their users similar practicality, making it increasingly sensible for the school to style mobile-based teaching and learning activities. Android, by increasing the user base, might hasten the integration of mobile technology into the learning experience and provide students and school new ways that to interact with content. Many of the tools that support mobile learning are usually higher suited to communication and data-gathering than to creative e orts like writing a paper, putting along a video retrospective, building a series of charts and graphs, or making a class presentation. Like Apple’s iOS products, Android will integrate with devices including laptops, netbooks, and tablets, though in the case of automaton, the list of connectable devices is longer. This interconnectivity provides an simple manner for college kids to move data from their sensible phones to locations wherever it will be shared with others and used in the development of individual and group comes.

Why Java so Popular?

Java program writing language is situated compile once and run rule everywhere. Major debate among developer is the fact that how java features platform independent while other program writing language will not support. The primary reason behind this article is the fact that Java makers can start run time environment for each and every platform. Quite simply, Java is with the capacity of creating JRE for each and every operating system. After the code is complied, source code is changed into machine readable form (byte code form).

Understanding Java Compiler:

Complier is a system which used to compile the foundation code into machine readable terms; it could be referenced as byte code. We are able to just suppose compiler as doctor which says patients (java program) where in fact the issues lies. The java is helped because of it code to perform and perform in virtually any environment.

Compiler ——-> Java program ——-> Byte Code ——> Execute (.school file)

Java Runtime Environment (JRE):

The prebuilt classes that are given Java originator are bundled in Jar document known as rt.jar. This document is expansion to class data files that are prepared to be performed in java runtime environment. You must locate rt.jar record in   C:\Program Data\Java\jre1.7.0\lib. You may draw out these data files to perform an application efficiently.

Integrated Development Environment (IDE):

IDE is a development program, which can be used to create java code. It allows designers to save lots of whole lot of commitment when writing the planned program. You may take good thing about inbuilt functionality and shortcuts to make coding part lot simpler. Below are a few popular involved development platforms
Eclipse (MyEclipse)
IBM WebSphere Studio
Bordland JBuilder
NetBeans
BlueJ

Java Development Set (JDK):

JDK can be discussed as java development set up. This set up offers several tools to create, put together java program as well as environment to perform java software. With JRE, you do not have ability to put together and do java program.
