Quick Test Professional (QTP)

 

Quick Test Professional (QTP) is an automated functional Graphical User Interface (GUI) testing tool that allows the automation of user actions on a web or client based computer application. It is primarily used for functional regression test automation. QTP uses a scripting language built on top of VBScript to specify the test procedure, and to manipulate the objects and controls of the application under test.

 

 

WinRunner

 

WinRunner, Mercury Interactive’s enterprise functional testing tool. It is used to quickly

 

create and run sophisticated automated tests on your application. Winrunner helps you automate the testing process, from test development to execution. You create adaptable and reusable test scripts that challenge the functionality of your application. Prior to a  software release, you can run these tests in a single overnight run- enabling you to detect and ensure superior software quality.

 

LoadRunner

 

LoadRunner is divided up into 3 smaller applications:

 

The Virtual User Generator allows us to determine what actions we would like  our Vusers, or virtual users, to perform within the application. We create scripts that generate a series of actions, such as logging on, navigating through the application, and exiting the program.

 

The Controller takes the scripts that we have made and runs them through a schedule that we set up. We tell the Controller how many Vusers to activate, when to activate them, and how to group the Vusers and keep track of them.

 

The Results and Analysis program gives us all the results of the load test in various forms. It allows us to see summaries of data, as well as the details of the load test for pinpointing problems or bottlenecks.

 

TestDirector

 

TestDirector, the industry’s first global test management solution, helps organizations deploy high-quality applications more quickly and effectively. Its four modules Requirements, Test Plan, Test Lab, and Defects are seamlessly integrated, allowing for a smooth information flow between various testing stages. The completely Web-enabled TestDirector supports high levels of communication and collaboration among distributed testing teams, driving a more effective, efficient global application-testing process

 

Silk Test

 

Silk Test  is   a   tool  specifically designed for  doing  REGRESSION      AND

 

FUNCTIONALITY testing. It is developed by Segue Software Inc. Silk Test is the industry’s leading functional testing product for e-business applications, whether Window based, Web, Java, or traditional client/server-based. Silk Test also offers test planning, management, direct database access and validation, the flexible and robust 4Test scripting language, a built in recovery system for unattended testing, and the ability to test across multiple platforms, browsers and technologies.

 

You have two ways to create automated tests using silktest:

 

Use the Record Testcase command to record actions and verification steps as you navigate through the application.

 

Write the testcase manually using the Visual 4Test scripting language.

 

Record Testcase

 

The Record / Testcase command is used to record actions and verification steps as you navigate through the application. Tests are recorded in an object-oriented language called Visual 4Test. The recorded testreads like a logical trace of all of the steps that were completed by the user. The Silk Test point and click verification system allows you to record the verification step by selecting from a list of properties that are appropriate for the type of object being tested. For example, you can verify the text is stored in a text field.

 

Write the Testcase manually

 

We can write tests that are capable of accomplishing many variations on a test. The key here is re-use. A test case can be designed to take parameters including input data and expected results. This "data-driven" testcase is really an instance of a class of test cases that performs certain steps to drive and verify the application-under-test. Each instance varies by the data that it carries. Since far fewer tests are written with this approach, changes in the GUI will result in reduced effort in updating tests. A data-driven test design also allows for the externalization of testcase data and makes it possible to divide the responsibilities for developing testing requirements and for developing test automation. For example, it may be that a group of domain experts create the Testplan Detail while another group of test engineers develop tests to satisfy those requirements.

 

In a script file, an automated testcase ideally addresses one test requirement. Specifically, a 4Test function that begins with the test case keyword and contains a sequence of 4Test statements. It drives an application to the state to be tested, verifies that the application works as expected, and returns the application to its base state.

 

A script file is a file that contains one or more related testcases. A script file has a .t extension, such as find .t

 

Rational Robot

 

Rational Robot is a complete set of components for automating the testing of Microsoft Windows client/server and Internet applications running under Windows NT 4.0, Windows 2000, Windows 98, and Windows 95.

 

The main component of Robot lets you start recording tests in as few as two mouse clicks. After recording, Robot plays back the tests in a fraction of the time it would take to repeat the actions manually.

 

Other components of Robot are:

 

Rational Administrator Use to create and manage Rational projects, which store your testing information.

 

Rational TestManager Log  Use to review and analyze test results.

 

Object Properties, Text, Grid, and Image Comparators Use to view and analyze the results of verification point playback.

 

Rational SiteCheck  Use to manage Internet and intranet Web sites.

 

Applications:

 

E-Ticketing System

E-Commerce

Book Banking system

Industrial Robotics

Stock maintenance system
