JMeter functions are special values that can populate fields of any Sampler or other
-element in a test tree. A function call looks like this:
-</p>
-<p>
-<code>
-${__functionName(var1,var2,var3)}
-</code>
-</p>
-<p>
+element in a test tree. A function call looks like this:</p>
-Where "__functionName" matches the name of a function.
+<p><span class="code">${__functionName(var1,var2,var3)}</span></p>
+<p>
+Where "__functionName" matches the name of a function.
<br>
-
-
Parentheses surround the parameters sent to the function, for example ${__time(YMD)}
The actual parameters vary from function to function.
Functions that require no parameters can leave off the parentheses, for example ${__threadNum}.
-
</p>
-<p>
+<p>
If a function parameter contains a comma, then be sure to escape this with "\", otherwise JMeter will treat it as a parameter delimiter.
For example:
-
<pre>
-
${__time(EEE\, d MMM yyyy)}
-
</pre>
-
-If the comma is not escaped - e.g.
-<code>
-${__javaScript(Math.max(2,5))}
-</code>
- - you will get an error such as:
-
+If the comma is not escaped - e.g. <span class="code">${__javaScript(Math.max(2,5))}</span> - you will get an error such as:
<pre>
-
ERROR - jmeter.functions.JavaScript: Error processing Javascript: [Math.max(2]
- org.mozilla.javascript.EvaluatorException: missing ) after argument list (<cmd>#1)
-
-</pre>
-
- This is because the string "Math.max(2,5)" is treated as being two parameters to the __javascript function:
-<br>
-
-
-
-<code>
-Math.max(2
-</code>
- and
-<code>
-5)
-</code>
-<br>
-
-
+ org.mozilla.javascript.EvaluatorException: missing ) after argument list (<cmd>#1)
+ </pre>
+ This is because the string "Math.max(2,5)" is treated as being two parameters to the __javascript function:<br>
+ <span class="code">Math.max(2</span> and <span class="code">5)</span><br>
Other error messages are possible.

<b>
-
If an undefined function or variable is referenced, JMeter does not report/log an error - the reference is returned unchanged.
For example if UNDEF is not defined as a variable, then the value of ${UNDEF} is ${UNDEF}.
-
</b>
-
Variables, functions (and properties) are all case-sensitive.
-
<b>
-
Versions of JMeter after 2.3.1 trim spaces from variable names before use, so for example
${__Random(1,63, LOTTERY )} will use the variable 'LOTTERY' rather than ' LOTTERY '.

+<div class="subsection"><h2>19.1 What can functions do<a class="sectionlink" href="#what_can_do" title="Link to here">¶</a></h2>
+<p>There are two kinds of functions: user-defined static values (or variables), and built-in functions.<br>
User-defined static values allow the user to define variables to be replaced with their static value when
a test tree is compiled and submitted to be run. This replacement happens once at the beginning of the test
run. This could be used to replace the DOMAIN field of all HTTP requests, for example - making it a simple
matter to change a test to target a different server with the same test.
-
</p>
<p>
-
Note that variables cannot currently be nested; i.e ${Var${N}} does not work.
The __V (variable) function (versions after 2.2) can be used to do this: ${__V(Var${N})}.
In earlier JMeter versions one can use ${__BeanShell(vars.get("Var${N}")}.
-
</p>
-<p>
-This type of replacement is possible without functions, but was less convenient and less intuitive.
+<p>This type of replacement is possible without functions, but was less convenient and less intuitive.

+Variables allow one to replace only part of any given value, not just filling in blank values.</p>

With built-in functions users can compute new values at run-time based on previous response data, which
thread the function is in, the time, and many other sources. These values are generated fresh for every
-request throughout the course of the test.

+<p>
Functions and variables can be written into any field of any test component (apart from the TestPlan - see below).
Some fields do not allow random strings
because they are expecting numbers, and thus will not accept a function. However, most fields will allow
functions.
-
</p>
<p>
-
Functions which are used on the Test Plan have some restrictions.
JMeter thread variables will have not been fully set up when the functions are processed,
so variable names passed as parameters will not be set up, and variable references will not work,
so split() and regex() and the variable evaluation functions won't work.
The threadNum() function won't work (and does not make sense at test plan level).
The following functions should work OK on the test plan:
-
<ul>
-
-
-<li>
-intSum
-</li>
-
-
-<li>
-longSum
-</li>
-

+<li>property functions</li>
+<li>log functions</li>
</ul>
-
-
</p>
<p>
-
Configuration elements are processed by a separate thread.
Therefore functions such as __threadNum do not work properly in elements such as User Defined Variables.
Also note that variables defined in a UDV element are not available until the element has been processed.

+<p>Functions are referenced in the same manner, but by convention, the names of

+be omitted.</p>
+<p><b>Argument values that themselves contain commas should be escaped as necessary.
+If you need to include a comma in your parameter value, escape it like so: '\,'.</b>
This applies for example to the scripting functions - Javascript, Beanshell, Jexl - where it is necessary to escape any commas
that may be needed in script method calls - e.g.
-
</p>
<pre>
-
${__BeanShell(vars.put("name"\,"value"))}
-
</pre>
<p>
-
Alternatively, you can define your script as a variable, e.g. on the Test Plan:
-
-<pre>
-SCRIPT vars.put("name","value")
-</pre>
-
+<pre>SCRIPT vars.put("name","value")</pre>
The script can then be referenced as follows:
-
-<pre>
-${__BeanShell(${SCRIPT})}
-</pre>
-
+<pre>${__BeanShell(${SCRIPT})}</pre>
There is no need to escape commas in the SCRIPT variable because the function call is parsed before the variable is replaced with its value.
This works well in conjunction with the BSF or BeanShell Samplers, as these can be used to test Javascript, Jexl and BeanShell scripts.
-
</p>
<p>
-
Functions can reference variables and other functions, for example
-
-<code>
-${__XPath(${__P(xpath.file),${XPATH})}
-</code>
-
+<span class="code">${__XPath(${__P(xpath.file),${XPATH})}</span>
will use the property "xpath.file" as the file name
and the contents of the variable XPATH as the expression to search for.
-
</p>
<p>
-
JMeter provides a tool to help you construct
function calls for various built-in functions, which you can then copy-paste.
It will not automatically escape values for you, since functions can be parameters to other functions, and you should only escape values you intend as literal.
