CN7021 Coursework: Introduction to Selenium Testing Tool

This document provides an introduction to Selenium, an open-source framework for automating web application testing. It begins with an overview of Selenium, highlighting its significance in the quality assurance domain and its widespread adoption by leading corporations. The document then details the Selenium Suite infrastructure, including Selenium IDE, Selenium Grid, and Selenium WebDriver, explaining their respective roles. It outlines the advantages of using Selenium, such as its cost-effectiveness and adherence to DevOps and Agile principles, while also pointing out its limitations, like the lack of built-in image comparison. Furthermore, the assignment categorizes Selenium commands into actions, accessors, and assertions, providing examples of each. It also touches upon the use of VB Script in Selenium and describes the three stages of creating automated tests: locating elements, executing actions, and generating test reports. The importance of test reports is emphasized, and the document concludes by mentioning the use of Selenium Internet Driver for automating web applications and the role of TestNG in generating default reports.

Selenium tool

introduction
 Selenium is a moveable framework for analyzing web applications. It offers a
playback tool for authoring functional examinations without the necessity to
know a test scripting language (Selenium IDE). The analysis can then run against
majority up-to-date web browsers. It runs on macOS, Windows, and linux.
 Selenium is a set of an open source software analysis computerization
instrument which has developed into de-facto invention in the domain of quality
assurance. With numerous programming languages, browsers supported,and
leading operating systems Selenium is presently applied in production in world
leading corporations as Google,Fitbit, HubSpot,and Netflix. The whole suite offers
a series of resolutions for diverse testing needs and complications. We go further
to explain these testing instruments, and why Selenium remained significant
after a decade since its foundation. we will scrutinize what Selenium is made of.

Selenium Suite Infrastructure
 Selenium Remote Control/Selenium 1 was the first product produced
under the company’s line however,because of its limitations and the
following merge with WebDriver, it was soon denounced . The entire
Selenium structure can be envisioned through the picture below and
current research outlines 3 key merchandises which are still greatly
supported and documented by community: Selenium IDE, Selenium
Grid and the Selenium WebDriver, . They are described below

pros
 Selenium testing tool on the software market, which is offered for
free one and can contest with paid software's.
 Selenium tool following the DevOps and Agile storyline before these
terms were even applied in technology world. The entire system
used in the Selenium tool falls in the key principles behind the
DevOps, Agile and Continuous Delivery.

cons
 Selenium tool is one of modern computerized testing which uses the
codeless analysis. This method allows anybody without good
programming understanding to execute tests.
 It has no built-in picture comparison
 In the quality assurance procedure, there are complications in
computerizing picture confirmation. Effective and simple way to
choose whether an picture is showed properly on the monitor is to
observe physically.

Classification of Selenium
Commands
 Actions – assist in changing or manipulating the condition of
applications (e.g. click on some link or pick an preference from a
page).
 Accessors – Allow verification and storage of the application state (e.g.
consider command “storeTextPresent” – if the text is found on the
page, then it stores True else stores false).
 Assertions – assist in comparing expected as well as actual results.
They play a part of checkpoints and if both the values are equal, only
then the examinations case go through or else it be unsuccessful.
Therefore, Assertions help confirm whether the condition of the
application after performing the test case follows to the preferred
condition (e.g. waitForPageToLoad, VerifyText, ). Contentions have
three modes:

VB SCRIPT IN SELENIUM
 VB script can be defined as scripting language developed by
Microsoft.It is molded on the Visul Basic.Its make work is to provide
bindings in Selenium 2
 VB script has one type of data known as variant
 VB script work the same way as Javascript

Creating Automated Tests
 There are three stages to perform automated tests:
 locate an component on the web browser
 Execute an action on that specific element
 Test and builds a strong a test report with results

Testing and Reporting
 The generation of Report is extremely important as soon as the
Automation Testing, similarly as for the Manual examination. By
checking the result, you can certainly recognize the number of test
cases are flopped, skipped and failed. By inspecting the report, you
can come back to understand what the condition of the project.
 Selenium Internet Driver is applied in the automating the web-
application, nevertheless, it will not produce any reports. TestNG will
produce default report
