vTest is an automated functional and regression testing tool for web applications. It incorporates record, verify, playback and reporting capabilities. vTest supports both Microsoft Internet Explorer and Mozilla Firefox. All popular Internet technologies such as HTTP, HTTPS/SSL, JavaScript, DHTML, ActiveX, Java & Flash are supported. vTest also supports all major web application frameworks including ASP, ASP.NET, Java Servlets and JSP, PHP & CGI.

vTest allows you to record and test your entire application in minutes by simply pointing and clicking on your Web application. Without any programming, all objects are automatically captured and recorded as a graphical script which shows the steps in your script in the form of an icon-based tree. For those users who wish to use scripting, vTest uses JavaScript as the scripting language and provides a comprehensive JavaScript API that you can use to create customized test scripts.

vTest creates scripts that adapt very well when your application's user interface changes. Most of the competition creates scripts that simply use the object name/ID to identify an object in your application. vTest uses a sophisticated object identification algorithm to identify objects in your application. This allows vTest scripts to adapt very well to changes in an application's user interface.

Benefits:
* Automate functional and regression testing tasks and thus reduce time-to-market
* Enhance the efficiency of quality assurance engineers by allowing them to devote less time to manual testing and more time to test design
* Maximize reliability and robustness by providing the capability to run tests on demand or according to a set schedule without the need for any user intervention
* Does not require a programming background. For those users who wish to use their programming skills, vTest uses the industry standard JavaScript language
* Manage product evolution effectively by generating easily modifiable tests

The Web browser is probably the most frequently used software today, and many tasks are highly repetitious. The iMacros software relieves the repetition of checking on the same sites every day, remembering passwords, data upload, image download, online marketing and functional testing and regression testing web sites over and over. With our Internet Macros technology, you record these tasks once and then let iMacros execute them whenever you need them. Any combination of browsing, form filling, clicking, and data extraction can be recorded into an Internet macro. Support for FLASH, JAVA and Silverlight applets and web site response time measurements are part of the advanced editions. It also includes a command line interface and ActiveX control Scripting component for use with batch files and VBS (WSH) and .NET scripting.

The Scripting Edition performs functions normally found in applications costing thousands of dollars; the Scripting Edition is a low cost alternative to big name capture/replay testing tools. It includes an easy-to-use scripting interface that extends the popular Windows Scripting Host with the ability to replay Internet Macros and extract web page data. Users can also access this interface from Visual Basic, Visual C++, the new Microsoft .NET languages or any other Windows programming language that can access an ActiveX component, and perform unlimited data upload and management on web sites. The license includes a royalty-free distribution of the iMacros engine, so you can provide scripts to third parties.

Numap7 is highly automated and requires very few parameter choices by the user. This version runs significantly faster. Advanced features include network sizing and feature selection. Training data can be compressed using the discrete Karhunen-Loeve' transform (KLT). This basic version of Numap7 limits the MLP to 10 hidden units and limits the PLN to 10 clusters. Upgradable to commercial versions which lack these limitations. The classification (decision making) version of this software, called Nuclass7, is also available. Numap7.0 was developed by the Image Processing and Neural Networks Lab of Univ. of Texas at Arlington, and by Neural Decision Lab LLC.

Add Statistics, Discrete Probability, Standard Probability Distributions, Hypothesis Testing, Correlation and Linear Regression functionality to your .NET, COM, and XML Web service Applications.

Statistics Module
Incorporates topic from data presentation (incl. standard, relative and cumulative frequency tables), Basic Statistics (incl. measure of centrality, dispersion and relative location) and Grouped Data (incl. Sample Mean, Variance and Standard Deviation

Discrete Probability Module
Encapsulates the probabilistic study of finite set of events (i.e. discrete probability) and experiments with a finite number of outcomes (i.e. discrete random variables). Including: probability measures, union/intersection law, conditionals/complementary probability; cumulative distribution functions, mean/variance/expected return of Random Variable.

Correlation and Regression Module
Allows the user to investigate relationships between two variables. These finding can be used to predict one variable from the given values of other variables. We cover linear (Spearman's, t-test, z-transform) and rank (Spearman's, Kendall's) correlation, linear regression and conditional means.

Standard Probability Distributions Module
This module assists in the development of applications that incorporate the Binomial, Poisson, Normal, Lognormal, Pareto, Uniform, Hypergeometric,Weibull and Exponential probability distributions. The PDF, CPDF and inverse, mean, variance, Skewness and Kurtosis, random number generators are implemented where appropriate and/or their approximations.

Confidence Intervals and Hypothesis Testing Module
Presents two aspects of inferential statistics known as confidence intervals and hypothesis testing.

This product also has the following technology aspects:

3-in-1: .NET, COM, and XML Web services - 3 DLLs, 3 API Docs,...
Extensive Client Examples (Delphi, C#, VB.NET)
ADO Mediator
