2. 1. Introduction
I. HPE LoadRunner is a software testing tool from Hewlett Packard Enterprise. In Sept 2016, HPE announced it
is selling its software business, including Mercury products, to Micro Focus.
II. It is used to test applications, measuring system behaviour and performance under load. HPE acquired
LoadRunner aspart of its acquisition of Mercury Interactive in November 2006.
III. HPE LoadRunner can simulate thousands of users concurrently using application software, recording and
later analysing the performance of key components of the application.

3. 2. Architecture
The key components of HPE LoadRunner are:
I. Load Generator generates the load against the application by following
scripts
II. VuGen (Virtual User Generator) for generating and editing scripts
III. Controller controls, launches and sequences instances of Load Generator -
specifying which script to use, for how long.
I. During runs the Controller receives real-time monitoring data and displays status.
IV. Agent process manages connection between Controller and Load Generator
instances.
V. Analysis assembles logs from various load generators and formats reports for
visualization of run result data and monitoring data

4. 3. How LoadRunner Works
I. LoadRunner simulates user activity by generating messages
between application components or by simulating interactions with
the user interface such as keypresses or mouse movements
II. The messages/interactions to be generated are stored in scripts.
LoadRunner can generate the scripts by recording them, such as
logging HTTP requests between a client web browser and an
application's web server.
