Bugraptors know that the performance of any product is key component of that project, to measure the performance of the project we have expert team of performance testers who perform the testing by using various performance testing tools like Jmeter, LoadUI, Selenium web driver and deliver project which has good performance according to the requirements and end user’s perspective.

1. MeasurePerformanceof the Application– Using
Open Source PerformanceTesting Tools

2. Introduction
Performance is a major factor of better user experience, so you
required a tool which measures the system performance in all
aspects like in case of system speed or response to access the
web applications.
If performance of the application is not good then what?
After 3 to 4 seconds 40 to 50 percent of users or visitors will
leave the site if that site fails to respond the user or visitor
request. That will also leave the negative impression on the user
or visitor regarding that.

3. Introduction
What should you do?
• To overcome these types of situations or to provide better user
experience, performance testing is the best option. In today’s era, it
is mandatory to measure the performance of the applications before
launching that application because it directly affects the
organization repo and its market value.
• In today’s era organizations should treat performance as a feature of
the web application and it’s mandatory to measure its performance
before launching that application.
• The goal of performance is to understand how your application will
behave in the normal and high or peak load conditions.
• There are various open source tools available in the market which
measures the performance of the web and mobile applications. Paid
tools are also available in the market for measuring the application
performance.

4. Why prefer open source performance
testing tools?
We have following reasons to choose open source performance
testing tools:
• Free or Modest.
• No initial cost involved other than learning curve and training.
• Customizable and Extensible.
• Easy to use to test at small loads.
• Cross Platform.

5. Popular open source performance testing
tool
1. Apache JMeter: Jmeter is one of the leading tools used for
load testing of web and application servers with the ability to
measure performance. Jmeter is a java based desktop
application which designed to evaluate the performance of the
web application under the normal and peak load conditions.
By using Jmeter we can evaluate the performance of both the
resources i.e. Static and Dynamic and these are followings:
• Files
• Servlets
• Perl Scripts
• Java Objects
• Data Bases and Queries
• FTP Servers

6. Popular open source performance testing
tool
2. The Grinder: The Grinder is a java based framework i.e. is
available under a BSD style open source license. The Grinder is
an open source testing framework that allows the running of
tests on multiple machines simultaneously.
• The Grinder uses Jython to make the test scripts for the
testing purpose of applications.
Features of the Grinder are as following:
• It uses Jython to create test scripts.
• It supports multiple protocols.

7. Popular open source performance testing
tool
3. OpenSTA: OpenSTA aka Open Systems Testing Architecture
stores a testing architecture which is based on CORBA to
empower you for running tests across different networks.
Current OpenSTA tool set has the ability to perform scripted
HTTP and HTTPS heavy load tests.
Tests are performed using simple scripts, recordings and it also
takes into account various results and statistics.
4. LoadUI: LoadUI is an open source tool to perform a load test.
This open source test tool is responsible to execute load tests as
well as performance tests.
LoadUI is very useful and powerful testing tool which allow the
user to create and update the test cases at the time of run.
LoadUI testing is called drag and drop testing which is very
useful for doing testing of complex load tests.

8. Popular open source performance testing
tool
5. Locust: Locust is popular performance testing tool i.e. used by
the different companies. Locust performance framework is
written in python. Performance scripts are also written in pure
python for the Locust. Locust mainly built for the HTTP web
based testing. Locust also figures out how many parallel users a
system can handle. Locust has a good web-based UI and it is
good for the testing of the API’s.
6. Selenium WebDriver: Selenium WebDriver is one of the most
fascinating automation testing tools. Selenium Web Driver is
used to automate the web application testing to verify that it is
working as expected. Selenium WebDriver supports many
browsers like Firefox, Chrome, IE, and Safari.

9. Popular open source performance testing
tool
6. Selenium WebDriver: Selenium WebDriver also supports
different- different programming languages i.e. C#, Java, Perl,
PHP, and ruby. Selenium WebDriver uses these programming
languages to write test scripts. Also, Selenium WebDriver is
platform independent that means same code run on different
OS i.e. MS Windows, Apple OS and Linux.
The Selenium WebDriver is considered to be one of the most
widespread testing tools with Selenium IDE, Selenium Remote
Control, Selenium Client API and Selenium grid at its disposal.

10. Popular open source performance testing
tool
7. WebLOAD: WebLOAD is a load testing tool i.e. used for the
web as well as for mobile. This tool evaluates the performance
and scalability of the application as well as it also evaluates the
verifiability of the application. Verifiability means “validating the
correctness of return results”. WebLOAD uses Javascript to write
test scripts.
• The webload testing tool supports multiple protocols for
testing and these are followings:
• REST/HTTP with Ajax support
• SOAP/XML
• FTP/SMTP

11. Now the question is which tools will be
better to use from all these above-
mentioned tools?
• All these tools have its own specialty. That all depends on the
application requirement and client requirement as well as the
knowledge level or the comfort level of the QA, which will
evaluate the performance of the application.
• If the client wants to do the performance testing with the
specific tool like JMeter or any other tool then you have to
evaluate the performance of the application with that tool
only. If some of the QA’s are comfortable with the tool’s GUI
then they will proceed with the Jmeter, OpenSTA, LoadUI, and
Selenium WebDriver. If QA is more comfortable with the
programming language and wants to perform testing using
programming languages like Java and python then they can be
used Locust and The Grinder etc.

12. Now the question is which tools will be
better to use from all these above-
mentioned tools?
• It depends on the tool’s capability to test the application with
the massive amounts of load i.e. application will behave
normally as we increase the number of users or we can say
that increase the load.

13. Concluding Remarks
• In modern web development, performance testing is of
supreme importance. These days, all user wants its application
(Web application) respond quickly to its request even
thousands of user access that application simultaneously. For
the user expectation, the performance of the application must
be quite well. That will be achieved only when we measure
the performance of the application before launching it into
the market by using performance testing tools.

14. Performance Testing at Bugraptors
• We at BugRaptors, equipped with a team of experts which
execute the performance testing of the application. We
implement the performance testing effectively to determine
the application speed is quite well under the normal and peak
load conditions and application work correctly as per the
business requirements and end-user perspective.
