I have a variable CCODE.
In my Cookie Manager, I set:
Name = AAA
Value = ${CCODE}
Results Tree shows AAA=${CCODE}.
I'm very sure the variable CCODE exists because I can use it elsewhere.
The following in user.properties:
CookieManager.save.cookies=true
CookieManager.check.cookies=false
CookieManager.allow_variable_cookies=true
How to solve this ? Thanks.
Take a look at:
JMeter's test elements execution order
JMeter Scoping Rules
Given the ${CCODE} variable exists and has its respective value (you can check it using Debug Sampler and View Results Tree listener combination) JMeter will send the relevant cookie along with the request.

When I execute the script with Loop count = 2
The sampler's names in the first loop will be displayed correctly in the "View Result Tree".
But the names for the same sampler's in the second loop will be empty/blank in the "View Result Tree", please check the screenshot below.
Your question doesn't provide sufficient level of details in order to be troubleshooted/reproduced.
If you're generating your sampler labels dynamically using JMeter Functions or Variables (like I did in the above demo) - double check their values at every step using Debug Sampler and View Results Tree listener combination, it might be the case they're getting overwritten/emptied somewhere somehow
Inspect jmeter.log file for any suspicious entries, if something goes wrong most probably you will be able to figure out the root cause or get the idea from there
I faced with same issue. The cause of the error is when the name is changed in HTTP Header Manager plugins, sampler names start to come undefined. This is a bug of JMeter.
The solution is very simple. If the default value:
HTTP Header Manager
is assigned to all HTTP Header Manager plugins in Jmx, it will be resolved.
I have an http request that uses an extractor to set a JMeter variable (lets call it test) from the body. When I look at the debug controller I can see this works fine. Next I want to append something to the beginning of the variable so I add a user defined variable node and add a variable with the name new and I set the value to ${test}. However when I look in the debug response I see ${test} instead of the value.
I tried the same thing setting the value manually in 2 different UDV nodes and it works fine, so how do I append to a JMeter variable declared in an extractor?
As per JMeter Documentation:
The User Defined Variables element lets you define an initial set of variables, just as in the Test Plan.
Note that all the UDV elements in a test plan - no matter where they are - are processed at the start.
So the User Defined Variables element will be read only once and only when the Test Plan is started.
If you need to overwrite the current variable with a new value you can go for i.e. __groovy() function, the relevant syntax would be something like:
${__groovy(vars.put('foo'\, 'some_prefix_' + vars.get('foo')),)}
Demo:
vars is a shorthand for JMeterVariables class instance, it provides read-write access to all JMeter Variables in the current thread scope. Check out The Groovy Templates Cheat Sheet for JMeter to learn what else you can do with Groovy scripting in JMeter tests
UDVs can't be used in dynamic way because they are process once at the start of the test.
Don't use UDV, use JSR223 Sampler (or PostProcessor) with vars;
vars.put("new", "prefix"+ vars.get("test"))
Another option is to use Set Variables Action plugin
I have looked at numerous examples of setting properties from cookies, and they all seem to be indicate that using a BeanShell PostProcessor, I should be able to do the following, given a cookie named 'FOO'.
props.put( "fooCookie", "${COOKIE_FOO}" );
However, when I try to write that value to the console, as you see here...
print( props.get( "fooCookie" ) );
... the value is always the string ${COOKIE_FOO} as if the dollar/curly bracket notation is not being parsed.
I feel like I must be missing something painfully obvious here, but after several hours of fighting this, I am bringing it to the experts. Any advice would be appreciated.
EDIT: Adding a bit more detail. This is the layout of my test plan
Test Plan
User Defined Variables
HTTP Cookie Manager
HTTP Request Defaults
Login Thread (setup)
[page request - login POST]
HTTP Header Manager
BeanShell PostProcessor
[more page requests]
And I do indeed have CookieManager.save.cookies=true set in the jmeter.bat file that I am launching it with.
Do you have HTTP Cookie Manager in your test plan? If not, you need to have that.
You also need to set the CookieManager.save.cookies=true in the jmeter.properties file which you can find in JMETER_HOME/bin folder.
${COOKIE_FOO} will return the actual cookie value.
Check that your ${COOKIE_FOO} variable is really set using Debug Sampler and View Results Tree listener combination. Your code is OK so my expectation is that the variable is not set.
Those who suggest using Beanshell where it is possible to handle the situation using JMeter built-in test elements should probably consider quitting IT. There are:
__setProperty() function to put something to JMeter Properties
__P() and/or __property() function to read something from them
See How to Use Variables in Different Thread Groups guide for real-life example.
I have a series of interconnected pages to test using JMeter. The problem is that the initial page has a Javascript variable in source section which is more of a session variable. This variable is passed in the URL for subsequent pages.
So basically I would like to fetch this javascript variable when I load the initial page from the source section and pass it to next URL(s).
Is there a way I can achieve this using JMeter.
Are you able to see the session variable in the response of initial page?
(in view result tree listener)
If yes, then correlate this value and pass the variable in to next request (use regular expression extractor for fetching the value, still if you are finding some issue in correlating the value than please share the response of first request over here so that I can provide you regx for that)
People mostly Regular Expression Extractor to fetch dynamic values from previous responses, in general the process looks like:
Add Regular Expression Extractor as a child of the request which returns desired data
Use Perl5-style regular expression to match what you're looking for
Provide a template to choose match group - ususally $1$ if you looking for a single value
Provide a reference name to refer the extracted value, i.e. foo
Use extracted value as ${foo} where required
You can visualise JMeter Variables using Debug Sampler and View Results Tree listener combination.
The easiest way to debug your regular expressions is using View Results Tree listener in "RegExp Tester mode"
See How to debug your Apache JMeter script article for more information on troubleshooting your JMeter test.
I'm trying to generate a jmeter script where a unique folder is created each time the script is run - adding a variable of some sort to the folder name, such as a username+timestamp, should be enough to guarantee uniqueness. However, jmeter is not resolving the variable to its value - although it is when the variable is read out of a csv file (which isn't suitable).
Basically, I'm editing the PostBody in the http request, as follows:
{"alf_destination":"workspace://SpacesStore/90368635-78a1-4dc5-be9e-33458f09c3f6","prop_cm_name":"Test
Folder - ${variable}","prop_cm_title":"Test
Folder","prop_cm_description":"Test Folder"}
where variable is basically any variable I've tried so far (such as a random string, timestamp, etc.)
Can anyone suggest how to get the variable resolved?
You can use jmeter (since 2.9 version) uuid feature -> http://jmeter.apache.org/usermanual/functions.html#__UUID
${__UUID}
and
1) If you want just 1 value for the whole test, add a "User Defined
Variables" Config Element to your test. This will be evaluated when
you load the test script the first time.
2) If you want to have the value change for every thread execution,
but stay the same during each thread instance: under your 'Thread
Group', add a 'Pre Processors -> User Parameters' to your thread group
- and add the variable there.
Also, if you want the value to change each time the thread starts over
(each 'iteration' of the script within the thread group), you can
check the "Update Once Per Iteration" box on the User Parameters - and
it will get a new value each time it starts the thread over at the
beginning of th test script (within that thread group).

With JMeter 2.9, the following works:
In HTTP Request Sampler, Tab "Post Body" add for example your JSON data and include the variables in it:
{"uuid":"${new-uuid}"}
new-uuid is a user defined variable.
This will send (from View Results Tree, Tab "Request"/"Raw"):
POST data:
{"uuid":"a1b2c3d4e5f6"}
I did this by referencing a variable in the http request post body - ${formvalues} - created using a beanshell preprocessor which is appended to the http request sampler. Beanshell contents:
double random = Math.random();
String formvalues ="{\"alf_destination\":\"workspace://SpacesStore/90368635-78a1-4dc5-be9e-33458f09c3f6\",\"prop_cm_name\":\"Test Folder - ${uname}_" + random + "\",\"prop_cm_title\":\"Test Folder\",\"prop_cm_description\":\"Test Folder\"}";
vars.put("formvalues",formvalues);
So this creates a folder with the username (${uname}, taken from the csv) plus a random number - it's crude as there could potentially still be cases where the script tries to create a folder with the same name as an existing one, but it will work for my case.
suppose you have the value "NewYork" in jmeter variable "Location".
Use it like this in HTTP POST BODY DATA:
{location:"${Location}"} => which gets interpreted as {location:"NewYork"}
