What is JMeter?
Apache JMeter is an open source load testing application
which is purely developed in Java. Apache JMeter is mainly used to test the
performance and stability of an application.
What are the
different type of applications you can test with JMeter?
You can test mainly web applications, it all supports to
test PHP, Java, ASP.NET, web services, databases, mail servers, network etc.
What are the protocol
JMeter supports?
IT support more
than 10 protocols, here are some of the protocols that JMeter supports.
Web Protocol:
To test the web applications, it supports both HTTP and HTTPS protocols.
Web Services:
To test web services applications, it supports both SOAP and REST.
FTP: File Transfer
Protocol, it is used to test the FTP servers and applications.
Database via
JDBC: It is used to test the database applications.
LDAP: Lightweight
Directory Access Protocol
Message-oriented
middleware (MOM) via JMS
Mail – It is
used to test mail servers such as SMTP(S), POP3(S) and IMAP(S)
MongoDB
(NoSQL): it is recently supported protocol by JMeter.
Native
commands or shell scripts
TCP
Why do you choose JMeter
as your performance testing tool?
JMeter is an open source tool and is widely used tool in the
market and it has the large online community support and is developed in pure
Java and you can test more than 10 protocols.
What is the
difference between JMeter and Loadrunner?
JMeter
|
Loadrunner
|
JMeter is an open source tool.
|
Loadrunner is one of the costliest tools in the market.
|
JMeter is primarily focusing on web and Java protocols.
|
Loadrunner supports more than 50 protocols.
|
JMeter has good online community support.
|
Loadrunner has technical support, but they hardly resolve your issue.
|
JMeter is a standalone application and there is no centralized
process.
|
You can operate Loadrunner from a centralized process such as performance
center.

What is a Listener? What
are the different type of listeners?
Listener is a graph or an image that shows the results of
different samplers. You have more than 50 listeners through standard JMeter and
JMeter plugins.
List of listeners are: Aggregate graph, Aggregate report, Assertion
Results, Backend Listener, Bean Shell Listener, BSF Listener, Comparison
Assertion Visualizer, Distribution Graph (alpha), Generate summary results,
Graph Results, JSR223 Listener, Mailer Visualizer, Monitor Results, Response
Time Graph, Save responses to a file, Simple data writer, Spline Visualizer,
Summary Report, View Results in Table, View Results Tree.
What are timers and
what are the different timers available?
Timers is waiting time between requests, these timers are
used to simulate real user behavior during each request, this helps to simulate
real time production load on the server.
There are different timers available in JMeter: Bean Shell Timer,
BSF Timer, Constant Throughput Timer, Constant Timer, Gaussian Random Timer,
JSR223 Timer, Poisson Random Timer, Synchronizing Timer, and Uniform Random
Timer.
What is assertion and
what are the different type of assertions available in JMeter?
Assertions are used to define the check points in different
parts of the script, there are different type of assertions available Bean
Shell Assertion, BSF Assertion, Compare Assertion, Duration Assertion, HTML Assertion,
JSR223 Assertion, MD5Hex Assertion, Response Assertion, Size Assertion, SMIME
Assertion, XML Assertion.
