AppPerfect Load Test Introduction

AppPerfect Load Test helps you design and simulate usage traffic which can be used to test your application infrastructure for performance, reliability and scalability. AppPerfect Load Test targets the most commonly used application infrastructure: Web applications and databases.

The overwhelming majority of software being developed today is designed to work with a Web-based (HTML) interface. AppPerfect Load Test helps design and simulate HTTP requests (URLs) which can be targeted at your Web application infrastructure (Web server, J2EE AppServer.).

The software being developed today predominantly use databases as their data persistence mechanism. AppPerfect Load Test helps you design and simulate database queries (using JDBC) and target most commonly used databases.

As server-based, multi-tiered and distributed applications continue to supplant desktop-based applications, it has become increasingly important for software developers to test the entire application infrastructure to ensure it performs within acceptable parameters. Application behavior while serving multiple users often varies drastically from the same application's behavior while serving a single user.

This document helps you create the test by creating a Javascript file. Although it is possible to create/edit a test through UI, Scripting support provides user advanced features which are not possible through UI For e.g. writing a user-defined function to perform various actions in between execution of two task(s). Performing custom validations. AppPerfect Load Test provides extensive APIs for processing the DOM tree of the HTML response received after executing a task. User gets a control over execution of the test while it is being replayed.

The document is targeted for advanced users having knowledge of JavaScript language and using Java APIs. A script variable "engine" represents the Load Test scripting engine is available in global scope.

About AppPerfect Products

AppPerfect offers following products for complete and comprehensive solution for testing and monitoring the performance of your application. These products that are designed to help you test your application throughout the development life-cycle.

AppPerfect Java Unit Test:

AppPerfect Java Unit Test is a feature-rich wrapper for the popular JUnit and HtmlUnit testing frameworks for non-web and web-based Java projects respectively. It provides the Java programmer with an easy to use and fully customizable unit-testing environment, which can be integrated with popular Java IDEs as well as the project's build process.

AppPerfect Java Code Test:

AppPerfect Java Code Test reads your software code and analyzes it for optimization, errors, coding conventions, complexity and style based on industry-standard rules. Over 750 pre-defined, high-value rules can be applied to your code. AppPerfect Java Code Test is an ideal tool to perform code reviews on an on-going basis to ensure high quality of code.

AppPerfect Java Profiler:

AppPerfect Java Profiler profiles a Java Virtual Machine to assist you in understanding the behavior of your application as it performs its functions. AppPerfect Java Profiler recognizes that your application does not operate in a vacuum and hence provides a unique blend of Java information combined with operating system information.

AppPerfect App Test:

AppPerfect App Test performs regression and functional testing of your Windows/Desktop applications. Performing manual functional testing by having a person sit and manually click away at the application is extremely expensive and error-prone. AppPerfect App Test provides the means to perform such labor-intensive activity in an automated manner.

AppPerfect Web Test:

AppPerfect Web Test performs regression and functional testing of your Web applications. Performing manual functional testing by having a person sit and manually click away at the application is extremely expensive and error-prone. AppPerfect Web Test provides the means to perform such labor-intensive activity in an automated manner.

AppPerfect Load Test:

AppPerfect Load Test is a stress/load testing tool that can simulate hundreds of virtual users from a single machine. Features supported include site recording, dynamic variable substitution, cookies support, session tracking, SSL support and run strategies. It can run tests based on a variety of strategies such as burst, incremental, exponential, quadratic or loop. It also provides you a comprehensive solution to monitor various attributes of various operating systems present in your application infrastructure.

AppPerfect Test Manager:

The AppPerfect Test Manager is central server with a Web-based UI for accessing various modules in the server. AppPerfect Test Manager consists of five main modules:

Requirements Manager: This module is used to create requirement specifications around which your tests will be designed and executed. Functional, business, performance, technical and usability requirements should be defined here to ensure the tests cover all defined criteria.

Test Manager: Once tests have been designed, the Test Manager can be used to manage the execution of your tests. Automatically running tests on a specific schedule, notification of test results, saving of test results, etc. can be defined in this module.

Results Manager: Once results for your various tests have run a few iterations, the Results Manager can be used to manage the archived results. Trend Analysis of multiple results to detect key quality trends is a key feature of this module. Storage management can also be performed via this module.

Issues Manager: As tests are run, issues such as defects, enhancements, modifications, etc. will occur. This module can be used to create and track such issues. This module is designed as a light-weight issues manager that seamlessly integrates with the rest of the server and is not intended to replace full-featured issues management system.

License Manager: Floating/site licenses are managed using this module. This module acts as the central manager for issuing and reclaiming floating licenses for the AppPerfect products.

AppPerfect Agentless Monitor:

The AppPerfect Agentless Monitor is an agentless, Web-based monitoring solution. It helps you monitor your applications and the underlying system resources. The AppPerfect Agentless Monitor consists of:

AppPerfect Monitor: A pure Web-based solution that helps you monitor your application infrastructure. Provides a rules engine to define alerts: a notification server for email and SMS notifications. Also includes a powerful report designer to create custom reports to analyze and understand the performance data.

AppPerfect Monitors: A series of modules designed to support specific devices. AppPerfect Monitor does not use the traditional agents-based approach to monitoring. Apart from being expensive, agents-based approach is also highly complex and error-prone. AppPerfect Monitors are designed to impose negligible overhead on the monitored system. These monitors are superbly optimized programs providing the maximum amount of information while imposing the lowest possible overhead.

Currently, the following devices are supported:
