I) Introduction Performance Testing:

1) What is Performance Testing?

Independent Testers conduct Performance Testing at System Testing Level using Black Box Test Design Techniques.

2) Types of Performance Testing:

We have different types of performance testing like Load Testing, Stress Testing, Spike Testing, Endurance Testing, and Volume Testing.

3) How to conduct Performance Testing?

Generally Software Testing can be done in two ways,

1) Manual Testing,

2) Automated Testing.

However& Manual Testing is not practical for Performance Testing and only Automated Testing is possible.

4) Performance Test Tools

We have several test tools are available for performance Testing, Apache JMeter, Micro Focus LoadRunner, IBM RPT, Silk Performer, WebLoad, and NeoLoad etc…

5) Performance Test Life Cycle

Important Steps in Performance Test Life Cycle are:

*Identify the Testing Environment

*Identify Performance Metrics,

*Plan and Design Performance Tests, *Configure the Test Environment, *Implement your test design,

*Run / Execute Tests and Analyze,

*tune and retest.

Introduction to Apache JMeter:

BIIT the best institute for Software Testing: Apache JMeter Course in East Delhi.

What is Apache JMeter?

Apache JMeter is an open source, 100% Java based application with a graphical user interface.

Advantages and Disadvantages of JMeter:

Advantages.

Open Source,

Ease of Use,

Platform Independent,

and Multi Protocol Support etc…

Disadvantages.

Web Application only,

Memory Consumption

and Lack of support for JavaScript…

JMeter vs LoadRunner.

How does JMeter Work?

Installation of JMeter.

Download and Install Java Software,

Set JAVA_HOME Environment Variable, Verify Java Installation,

Download Jmeter and unzip and Launch / Start JMeter.

Elements of JMeter Test Plan.

Thread Group.

A Thread Group is a set of threads executing the same scenario. Virtual user groups are represented by Thread Groups.

Controllers.

JMeter has two types of Controllers:

Samplers and Logical Controllers.

These drive the processing of a test.

Samplers:

Samplers tell JMeter to send requests to a server and wait for a response.

Logic Controllers:

Logic Controllers let you customize the logic that JMeter uses to decide when to send requests.

Listeners:

Listeners are the JMeter component that displays test results.

Timers:

By default, a JMeter thread executes samplers in sequence without pausing. We recommend that you specify a delay by adding one of the available timers to your Thread Group.

Assertions:

Assertion in JMeter is used to validate response of the request, that you have sent to the server. Assertion is a process where you verify expected result with the actual result of the request at run time.

Configuration Elements:

Config elements in JMeter are used to configure or modify the sampler requests made to the server. They do not send requests, configure or modify the sampler requests.

Pre-Processor Elements:

PreProcessors are JMeter elements that are used to execute actions before the sampler requests are executed in the test scenario.

Post-Processor Elements:

A Post-Processor executes some action after a Sampler Request has been made. If a Post-Processor is attached to a Sampler element, then it will execute just after that sampler element runs.

Building a Test Plan:

A test plan describes a series of steps JMeter will execute when run. A complete test plan will consist of one or more Thread Groups, logic controllers, sample generating controllers, listeners, timers, assertions, and configuration elements.

Recording Tests Using JMeter:

1) Creation of Thread Group

2) Adding HTTP Proxy Server

3) Configuring HTTP proxy server

4) Configuring the browser for recording the test script

5) Capturing the test steps using JMeter

Enhancements in Test Scripts:

1) Parameterization

2) Correlations

3) Validations

4) Debugging Script

5) Assertions

6) Error Handling Etc…

JMeter Result Analysis:

Running a test plan is only 50% of the performance testing task.

Running Multiple Scripts with JMeter:

1) Creating multiple test thread groups

2) Calling the multiple thread groups from a test plan

3) Configuring the threads groups with respective users numbers and ratios

3) Running the load test for multiple thread groups from a Single Test

4) Analyze the user group specific issues

5) Analyze the Test plan specific issues for all user groups.

Different Types of JMeter Test Plans:

Web Test Plan.

Build a simple test plan which tests a web page.

JMeter – Database Test Plan.

Create a test plan to test the database server.

JMeter – FTP Test Plan.

Create a Test Plan to test the FTP site.

JMeter – Webservice Test Plan.

Create a Test Plan to test a WebService

JMeter – JMS Test Plan.

Create a test plan to test Java Messaging Service (JMS).

Jmeter Distributed (Remote) Testing.

Distributed testing enables having a local JMeter (master) that handles the test execution, together with multiple remote JMeter instances (slaves) that will send the request to our target server.

JMeter Functions, Variables, and Regular Expressions.

JMeter Functions can be used for many different operations, including: inputting information from a file, performing math calculations and value generation, processing strings, evaluating JMeter variables, working with JMeter properties and executing scripts like Javascript or BeanShell script.

JMeter Best Practices.

Limit the Number of Threads

Your hardware capabilities as well as the Test Plan design will both impact the number of threads you can effectively run with JMeter.

Reducing resource requirements

Use non-GUI mode, use as few Listeners as possible; only save the data that you need, use as few Assertions as possible.

Use Variables

This functionality allows changing parameters in multiple places of the Test-plan.

Distributed Testing

Once you reach the limits of one machine, you can switch to distributed or remote testing.

BeanShell server

The BeanShell interpreter has a very useful feature – it can act as a server, which is accessible by telnet or http.

Parameterising tests

Often it is useful to be able to re-run the same test with different settings. For example, changing the number of threads or loops, or changing a hostname.
