I'm working with JMeter. I'd like to specify the test host using user defined variables, like this:
variable name value
localhost localhost
test 192.168.0.1
hostname ${localhost}
Executing the test, I see that the hostname value is not substituted, and obviously the test fails. I know I can use properties and pass the hostname from the command line, or simply change the hostname value. Is it possible to it like I've explained?
Thanks.
I've managed to solve my problem. I've changed the hostname variable value to: ${__evalVar(${localhost})}, but I've got this error:
ERRROR jmeter.functions.EvalVarFunction: Variables have not yet been defined
So I've moved the hostname variable declaration in a "User defined variable" child node of my Sampler node. That solved it.
To solve this you should use hostname = ${__eval(${localhost})}
http://jmeter.apache.org/usermanual/functions.html#__eval
Carlos' answer has a mistake (which I can't comment on due to rep) as it uses evalVar, this requires as an argument a plain string:
This works: ${__evalVar(localhost)})
This works: ${__eval(${localhost})}
This doesn't work (the current answer): ${__evalVar(${localhost})}
http://jmeter.apache.org/usermanual/functions.html#__evalVar
Check this forum:
from Blazemeter
For example: getting value of varible "listid_XXX" where the XXX number comes from an index variable:
${__V(listid_${idx1})}
New newer versions (from 2.2), you can use ${__V(${...})}/.
Ex: ${__V(${SERVER_CONTEXT})}/rest
As #Alies Belik mentioned, if you get
ERRROR jmeter.functions.EvalVarFunction: Variables have not yet been defined
then define the 2nd variable in next other UDV (User Defined Variables) node.

Using node-red-contrib-telegrambot palette it is possible to set up bot's token from an env variable using the following syntax {env.get("BOT_TOKEN")}.
But is it possible to do the same for the bot's name?
To populate any fields of a node in the editor from environment variables you need to use the following syntax:
${BOT_TOKEN}
You can find the docs here
I am getting below error message when creating VM from existing parameter.json and template.json file.
Code : InvalidDeploymentParameterValue
Message : The value of deployment parameter 'publicIPAddresses_azuse2qaautovm2_ip_name' is null. Please specify the
value or use the parameter reference. See https://aka.ms/arm-deploy/#parameter-file for details.
You need to provide a value for that parameter (in a parameters file) publicIPAddresses_azuse2qaautovm2_ip_name or provide a default value for that parameter.
I want to use the result which is "id" and use it in the second request POST
Saving it as environmental variable in the first request(under tests)
var jsonData = JSON.parse(responseBody);
postman.setEnvironmentVariable("id", jsonData.token);
Here is the second request looks like, not sure what I am doing wrong here
Your request is correct.
As long as you set an environment variable, you may USE this environment. From your print screen I see "no environment" on the top right corner.
I suggest either you create an environment where to save your environment variables and then use it or you use a global variable, postman.setGlobalVariable("id", ...) instead

Here is the simple code
vars.put("str" , "${__time(dd/mm/yyyy HH:MM:SS)}");
log.info("${str}");
I am expecting to see the value of str in logs but I am getting ${str}. I am validating it because I have to assign the current time to a variable and later want to use it in script. But I am not getting the value stored in str.
try as follows using vars.get:
vars.put("str" , "${__time(dd/mm/yyyy HH:MM:SS)}");
log.info("str " + vars.get("str"));
I wouldn't recommend inlining functions and/or variables into Beanshell script as you may face syntax error issues, i.e. type mismatch if the value has quotation marks.
So either use log.info(vars.get("str")); or use Debug Sampler and View Results Tree listener combination to see JMeter variables values.
More information: How to Debug your Apache JMeter Script
I'm very new at JMeter issues.
In a test script i have a BeanShell PreProcessor element that updates some variables previously defined at a "User Defined Variables" element.
Latter those variables are used in "Http Requests". However, the value that is used in the http request is the default one.
The scripts seems to be working due to some debug print();
My question is if it's necessary to delay the script to be sure that the BeanShell finishes?
Thanks a lot for your attention
There is no need to put any delay to Beanshell Pre-Processor as it's being executed before request. I'd recommend to check your jmeter.log file to see if there are any scripting issues as Beanshell Pre-Processor does not report errors anywhere including View Results Tree listener.
There are at least 2 ways to assure that everything is fine with your Beanshell script:
Put your debug print code after variables replace logic to see if it fires
Use JMeter __Beahshell function right in your HTTP request. If it's ok - View Results Tree will demonstrate beanshell-generated value. If not - the field will be blank and relevant error will be displayed in the log.
Example test case:
Given following Test Plan structure:
Thread Group with 1 user and 1 loop
HTTP GET Request to google.com with path of / and parameter q
If you provide as parameter "q" following beanshell function:
${__BeanShell(System.currentTimeMillis())}
and look into View Results Tree "Request" tab you should see something like:
GET http://www.google.com/?q=1385206045832
and if you change function to something incorrect like:
${__BeanShell(Something.incorrect())}
you'll see a blank request.
The correct way of changing existing variable (or creating new if variable doesn't exist) looks like
vars.put("variablename", "variablevalue");
*Important: * JMeter Variables are Java Strings, if you're trying to set something else (date, integer, whatever) to JMeter Variable you need to cast it to String somehow.
Example:
int i = 5;
vars.put("int_i", String.valueOf(i));
Hope this helps.
You can update the vale of a "user defined variable".
You have to create a bean shell sampler
vars.put("user_defined_variable", "newvalue");
#theINtoy got it right.

I'm new to jmeter too but as I know variables defined in "User defined variables" are constants, so you can't change them. I recommend to use "User Parameters" in preprocessors or CSV Data Set Config.
