Executive Summary
This document explains about Loadster Load testing and provides the details about the steps that
are required to perform the load test. This document is prepared after the successful
implementation of the Load Test in one of our customer projects. The blog, essentially, gives you
an idea of how Load Testing is considered to be a method to determine how an application will
behave under load. “Load”, generally, refers to the total user traffic at a given time. This
document also explains how Load testing software can be used to gain knowledge about several
different metrics like stress, stability, spike, scalability, baseline.
Loadster workbench is an integrated environment which enables you to perform load testing.
Load test can be performed using any number of virtual users. It gives us provision to record and
edit the scripts and the test results are obtained after performing the test. It has an in-built load
engine through which we can perform load testing with concurrent virtual users.
Project Repository
Loadster has a repository called project repository for each project, script etc. Test results, after
completing the load test, is also stored in this repository.
Dashboard
When the load test starts providing information, regarding the number of users, time taken to
complete the test is displayed on the dashboard. In spite of that, there are number of options
provided on the left side of dashboard namely response times, network throughput, transaction
throughput, transaction, error, virtual user, and load engine information. You can view a graph of
load test by clicking on any of these options as the load test runs.

Steps to perform load testing
The steps included in load testing are as follows:
Step 1: Scripting
It represents the actions performed by a user or a number of users during load test. It can be
created manually or scripts can be recorded. Multiple number of scripts can run during a load
test.
a) Recording Scripts
 Configure the port: Loadster has an HTTP/S proxy that can record traffic between your
web browser and the applications you are testing. The proxy runs on localhost port 1997
by default.
 Configure the web browser to use this port as proxy for recording traffic. For eg: In
Mozilla, Select options >Advanced >Network >Settings, select Manual proxy
configuration to configure the port. Click ok.
 Click on the record button in the script editor for recording the script.

 All the actions performed by the user in the above web browser will be recorded. After
completing the recording, click on „Stop Recording‟.
 Filter the unwanted requests by unchecking the respective recorded scripts. Click on done
recording.
 Then, the recorded traffic will be appended to the script.
b) Playing Scripts
 After recording the script, run the script with a single virtual user.
 Successful commands are indicated by three green dots under the http command.
 Errors are indicated by three red dots under the http command.
Step 2: Scenario
It is used to create a number of virtual users during a load test. We can configure the number of
users, scripts to be run for the users and load engine.

a) Creating a scenario
 After creating the project a scenario will be created. To add the virtual users click on „+‟
button.
 There are options to edit the number of users included in each group.
 A graph on the top shows the details of virtual user group. Each user group is
indicated by different color.
 There is a provision to add or remove user groups by clicking the „-„button.
 You can, also, change the built-in-load engine and select other option from the
list.

b) Running Load Test
 Once scenario has been created, click on launch test button, to start load testing.
 A popup displaying the fuel details is displayed. Click on „ok‟ button.
 A test dashboard window will be displayed which contains Response Times, Network
Throughput, Transactions, Transaction Throughput, Errors, Virtual users and Load
engines as shown below:
o Response Times: It is the time taken by a page or HTTP request to respond. On
clicking on the response times in the left side bar, a graph will be displayed which
indicates the response times per page for the duration of the test.
Loadster Testing
© RapidValue Solutions
o Network Throughput: It indicates the amount of data transferred between loadster
and the application during the load test. It is expressed in Megabits per Second
(Mbps). There is also a cumulative throughput graph which indicates the total amount
of uploaded or downloaded data during the load test. It is expressed in Mega Bytes
(MB).

o Transactions: This section displays a graph which shows any transaction (pages,
hits, and errors) as the load test runs.
Loadster Testing
© RapidValue Solutions
o Transaction Throughput: It displays a graph which indicates the number of actions
completed within a specified unit of time.
Loadster Testing
© RapidValue Solutions
o Errors: It displays any error which has been encountered during load test. There are
3 types of error graphs:
 Errors by type: This graph indicates how many times a particular error has
occurred. Each error is indicated by a different color and the count is also
shown in the graph.
Loadster Testing
© RapidValue Solutions
 Errors by page:-This graph indicates the number of times an error has occurred per
page. It shows the page details and the number of errors in each page.
Loadster Testing
© RapidValue Solutions
 Error breakdown: It displays the Group, User, Location, Error Type and Count
Information for each error occurred.
Loadster Testing
© RapidValue Solutions
 Virtual Users: This graph shows the virtual user progression and total number of
users in the test.
Loadster Testing
© RapidValue Solutions
o Load Engines: This shows information about CPU Utilization, Thread Count,
Memory Utilization and Latency.
 CPU Utilization: This graph shows information about how busy is the load
engine‟s CPU. If more than one load engine is used, each one will be
indicated by a different color.
Loadster Testing
© RapidValue Solutions
 Thread Count:-It indicates the total number of threads in use by a load engine.
Loadster Testing
© RapidValue Solutions
 Memory Utilization: It shows the amount of memory used by a load engine.
Loadster Testing
© RapidValue Solutions
 Latency: This graph displays the delay between loadster workbench and load engine.
It is expressed in seconds. There should be an appreciable network connection in
order to decrease the latency.

 A popup appears when the load test is finished. Click on „ok‟ button.
 A test result, corresponding to the load test that is executed, is generated.

Step 3: Analyzing the test results
a) A test report will be saved in the repository when the load test is completed. You can
either rename the display name of the report or delete the report.
b) Customizing the report: On clicking the „customize‟ button in the report you can enter the
title, summary and notes on the report.

c) Exporting an HTML report:- You can export the test report generated in HTML format
by clicking on „Export as Html‟ button. Then, you should specify the location where the
document should be exported. Once it is saved, a popup will be displayed. Click on „Ok‟
button.
