<p>
In this section, you will learn how to create a basic
<a href="build-test-plan.html">
Test Plan
</a>
to test a Web site. You will
create five users that send requests to two pages on the Jakarta Web site.
Also, you will tell the users to run their tests twice. So, the total number of
requests is (5 users) x (2 requests) x (repeat 2 times) = 20 HTTP requests. To
construct the Test Plan, you will use the following elements:
<a href="test_plan.html#thread_group">
Thread Group
</a>
,
<a href="../usermanual/component_reference.html#HTTP_Request">HTTP Request</a>
,
<a href="../usermanual/component_reference.html#HTTP_Request_Defaults">HTTP Request Defaults</a>
, and
<a href="../usermanual/component_reference.html#Graph_Results">Graph Results</a>
.
</p>
<p>
For a more advanced Test Plan, see
<a href="build-adv-web-test-plan.html">
Building an Advanced Web Test Plan
</a>

<blockquote>
<p>
The first step you want to do with every JMeter Test Plan is to add a
<a href="test_plan.html#thread_group">
Thread Group
</a>
element. The Thread Group tells
JMeter the number of users you want to simulate, how often the users should send
requests, and the how many requests they should send.
</p>
<p>
Go ahead and add the ThreadGroup element by first selecting the Test Plan,
clicking your right mouse button to get the Add menu, and then select
Add --> ThreadGroup.
</p>
<p>
You should now see the Thread Group element under Test Plan. If you do not
see the element, then "expand" the Test Plan tree by clicking on the
Test Plan element.
</p>
<p>
Next, you need to modify the default properties. Select the Thread Group element
in the tree, if you have not already selected it. You should now see the Thread
Group Control Panel in the right section of the JMeter window (see Figure 5.1
below)
</p>
<p><table border="0" cellspacing="0" cellpadding="0"><tr><td><img src="../../docs/images/screenshots/webtest/threadgroup.png"><br>
<font size="-1">
Figure 5.1. Thread Group with Default Values
</font></td></tr></table></p>
<p>
Start by providing a more descriptive name for our Thread Group. In the name
field, enter Jakarta Users.
</p>
<p>
Next, increase the number of users (called threads) to 5.
</p>
<p>
In the next field, the Ramp-Up Period, leave the the default value of 0
seconds. This property tells JMeter how long to delay between starting each
user. For example, if you enter a Ramp-Up Period of 5 seconds, JMeter will
finish starting all of your users by the end of the 5 seconds. So, if we have
5 users and a 5 second Ramp-Up Period, then the delay between starting users
would be 1 second (5 users / 5 seconds = 1 user per second). If you set the
value to 0, then JMeter will immediately start all of your users.
</p>
<p>
Finally enter a value of 2 in
the Loop Count field. This property tells JMeter how many times to repeat your
test. If you enter a loop count value of 1, then JMeter will run your test only
once. To have JMeter repeatedly run your Test Plan, select the Forever
checkbox.
</p>
<p><table border="1" bgcolor="#bbbb00" width="50%" cellspacing="0" cellpadding="2">
<tr><td>In most applications, you have to manually accept
changes you make in a Control Panel. However, in JMeter, the Control Panel
automatically accepts your changes as you make them. If you change the
name of an element, the tree will be updated with the new text after you
leave the Control Panel (for example, when selecting another tree element).

<p>
Now that we have defined our users, it is time to define the tasks that they
will be performing. In this section, you will specify the default settings
for your HTTP requests. And then, in section 5.3, you will add HTTP Request
elements which use some of the default settings you specified here.
</p>
<p>
Begin by selecting the Jakarta Users (Thread Group) element. Click your right mouse button
to get the Add menu, and then select Add --> Config Element --> HTTP Request
Defaults. Then, select this new element to view its Control Panel (see Figure 5.3).

<p>
Like most JMeter elements, the
<a href="../usermanual/component_reference.html#HTTP_Request_Defaults">HTTP Request Defaults</a>
Control
Panel has a name field that you can modify. In this example, leave this field with
the default value.
</p>
<p>
Skip to the next field, which is the Web Server's Server Name/IP. For the
Test Plan that you are building, all HTTP requests will be sent to the same
Web server, jakarta.apache.org. Enter this domain name into the field.
This is the only field that we will specify a default, so leave the remaining
fields with their default values.
