Im trying to loop over my user defined variables and add them to cookie manager.
Here is how I set it up:
But when I look at the results it only takes the FIRST var and uses that for ALL of the loops. So HTTP Cookie Manager is only replacing the first var.
This behavior is unexpected, have I set something up wrong? I added the debug sampler and I can see the vars are changing but for some reason http cookie manager is not replacing them
You need to define variable:
cookie_matchNr set to 3

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.
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 am trying to use Jmeter for API automation testing.
But Jmeter hasn't provided any separate containers for global and environment variables similarly like SOAP-UI and Postman.
I tried to use property file which also shared among all the JSR223 throughout the project but property having many others keys too and I haven't got any option by which I can delete key which been initiated once. Moreover, I can update the value too which seems most preferable to use
Below code I am using to set and get the values
props.put("shubhamKey", "shubhamValue")
props.get("shubhamKey")
I can also update it using same key
props.put("shubhamKey", "shubhamNewValue")
But as I said we can't delete key once initiated and it seems dangerous to delete from properties as it has many other keys too which may be required by Jmeter internally
After seeing too many things I have seen "User Defined Variables" where I can specify my key-value pairs. I am able to get the value using below code:
vars.get("shubhamLocalVariable")
But I am not able to set the value using below code:
vars.put("shubhamUserKeyagain","shubhamUservalue")
neither I got any option by which I further update it or delete it.
so Is there any feasible thing to store variables in Jmeter which can be easily created/deleted/updated using the code and can even call by other containers like HTTP Request.
Moreover I also want a container which preserve the values so the next iteration and next time (any time like other day) it will start with latest values
User Parameters
Jsr223
Any workaround will be helpful and appreciated in advance
As for me, I'm using a JSR223 Sampler at the begining of every Thread.
And for me it works:
vars.put("checksums_1","")
vars.put("checksums_2","")
vars.put("checksums_3","")
Firstly you can delete properties by using:
props.remove("shubhamKey");
And if you use specific prefix/suffix it shouldn't effect JMeter internally.
User Defined Variables isn't the best way to handle dynamic values, it's used for static variables
Note that all the UDV elements in a test plan - no matter where they are - are processed at the start.
But you can set variable by string or variable or function, e.g:
For defining variables during a test run, see User Parameters which use similar assignments.
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.
have been looking into JMeter recently. I need to get an authentication string from a cookie and use it when posting a request to a different path. The Auth string changes each time the login page is hit.
Is there a way in JMeter to use one cookie for all paths in a test when the paths are different?
IE-
Path to Get Cookie:
Webserver: someURL.net
Path: /some/login/path
Use the cookie value:
Webserver: someURL.net
Path: /somewhere/different
I have set the below JMeter properties to be able to use Cookies as needed.
CookieManager.check.cookies=false
CookieManager.save.cookies=true
CookieManager.allow_variable_cookies=true
When I run the samplers the result for the request to /somewhere/different
Returns [no cookies]
I can see the cookie data present in the Request when the path is /some/login/path
I have tried defining a User-Defined cookie but I need to get the auth string first to use it in the different path.
When I do this I can see the cookie data added to the request to /somewhere/different but the var is not being set. I don't think this is the right way to solve the challenge.
To get the auth string first I tried to use the Controller "User defined Variables" to store the cookie value and pass it back to the Cookie Manager- this did not work.
And I looked at using the RegEx extractor to get the value so I could use it but I'm not sure that this can be used to get cookie values?
My understanding is that you cannot use more than one cookie manager per Thread group. As I type this I realize that the solution might be that I must use separate threads and pass the cookie value from one thread to another.
Apologies if the question is framed poorly first time here, signed up to ask after searches didn't turn up a solution. If you need more info/screens of my JMeter set up for any of the scenarios I tried above I'll add them. And thank you.
I'm afraid you won't be able to manipulate cookies using built-in JMeter features, you'll need to go deeper and invoke JMeter API methods from scripting test elements.
For instance:
Add a Beanshell PostProcessor as a child of the first request
Put the following code into the PostProcessor(s) "Script" area:
import org.apache.jmeter.protocol.http.control.Cookie;
import org.apache.jmeter.protocol.http.control.CookieManager;
CookieManager manager = ctx.getCurrentSampler().getCookieManager();
for (int i = 0; i < manager.getCookieCount(); i++) {
Cookie cookie = manager.get(i);
if (cookie.getName().equals("your_cookie_name")) {
Cookie newCookie = cookie;
newCookie.setPath("/your/new/path");
manager.remove(i);
manager.add(newCookie);
ctx.getCurrentSampler().setCookieManager(manager);
break;
}
}
Change your_cookie_name and /your/new/path as per your requirements
It will create a new one with the different path. JMeter's HTTP Cookie Manager doesn't allow 2 cookies with the same name so the old one has to be removed.
