Performance Testing Basics in HP Loadrunner 12.53

Introduction

Latest Version  :           12.53
Developed       :           HP Software Division
OS                   :           Windows/ Linux (Load Generator Only)

HP LoadRunner is a software testing tool from Hewlett-Packard. It is used to test applications, measuring system behaviour and performance under load. HP acquired LoadRunner as part of its acquisition of Mercury Interactive in November 2006.

HP LoadRunner can simulate thousands of users concurrently using application software, recording and later analysing the performance of key components of the application.

LoadRunner simulates user activity:
·      by generating messages between application components
·      by simulating interactions with the user interface such as keypresses or mouse movements

It provides an efficient and robust means to verify that your application’s architecture is built for more efficient performance and reliability. LoadRunner helps you:

·         Test a broad range of applications, including the latest Web and Mobile technologies, ERP/CRM applications, and many legacy systems.
·         Run high-scale tests using minimal hardware, including any mix of physical and virtual
environments, including public Cloud infrastructure.
·         Identify end-to end performance bottlenecks using advanced monitoring and analysis tools,
·         and ensure that new or upgraded applications meet the performance requirements of your
business.

The key components of HP LoadRunner are:

·       Load Generator generates the load against the application by following scripts
·      VuGen (Virtual User Generator) for generating and editing scripts
·      Controller controls, launches and sequences instances of Load Generator - specifying which script to use, for how long etc. During runs the Controller receives real-time monitoring data and displays status.
·       Agent process manages connection between Controller and Load Generator instances.
·        Analysis assembles logs from various load generators and formats reports for visualization of run result data and monitoring data.

Modules are available to enable HP LoadRunner to capture, replay and script different application and networking technologies. These include support for:

·         applications using Microsoft .NET and Java
·         database servers such as Microsoft SQL Server and Oracle
·         internetworking protocols such as DNS, FTP and LDAP
·         e-mail protocols including IMAP, MAPI, POP3 & SMTP
·         remote client technologies such as Citrix ICA and RDP.

After the test completes, the LoadRunner analysis engine provides a single view of end-user
response time, infrastructure-level and code-level performance; and includes the patented
Auto-correlation engine to identify the most likely causes of performance issues.

Loadrunner ~ Performance Testing with Citrix Protocol : Recording Tips n Tricks!

1 . INTRODUCTION 1.1 Citrix Protocol in load runner Recording Tips When recording a script, be sure to follow these guidelines in order to create an effective script. Single vs. Multi-Protocol Scripts When creating a new script, you may create a single protocol or multi-protocol script. If you plan to record a simple Citrix ICA session, use a single protocol script. When recording an NFUSE Web Access session, however, you must create a multi-protocol script for Citrix ICA and Web (HTML/HTTP), to enable the recording of both protocols. Record into Appropriate Sections Record the connection process into the vuser_init section, and the closing process into the vuser_end section. This will prevent you from performing iterations on the connecting and disconnecting. Run a Clean Session When recording a session, make sure to perform the complete business process, starting with the connection and ending with the cleanup. End your session at a point from where you could sta
