I want to parametrize the testdata path, result path, server and port by defining them in environment variable.
I was able to achieve this to certain extent with System.getenv("Jmeter_Result") using it in BeanShell processor. But I need to use configuration element to fetch the value.
Can you kindly suggest.I am using Jmeter 3.1.
According to https://jmeter.apache.org/usermanual/functions.html#what_can_do, ${__BeanShell( ... )} may also help you on this issue.
For instance, one of our APIs needs OAuth2 authentication, and what I did was:
- Thread Group
- User Defined Variables
client_id = ${__BeanShell( System.getenv("client_id") )}
client_secret = ${__BeanShell( System.getenv("client_secret") )}
- Once Only Controller
- OAuth2 HTTP Request
- API HTTP Request
There is __env() function available via JMeter Plugins, it seems to be something you're looking for.
You can install __env() and other custom JMeter Functions using JMeter Plugins Manager.
If the environment variable is made available via a System property then
JMeter can access it using the ${__P("Jmeter_Result")} function.
Otherwise, it's trivial to pass in the value of an environment variable using
the -J option:
jmeter -JJmeter_Result=$Jmeter_Result

Does anyone know how to use java to change the HTTPrequest methods in Jmeter. I see a version of it but they use python. thanks
You can define whatever JMeter Variable you want in the "Method" input of the HTTP Request sampler like:
Given you properly define this ${METHOD} variable value you should be able to parameterise the HTTP Method by using external data sources, i.e. via CSV Data Set Config
I'm using HTTP Request Defaults to set host and port for a set of requests.
I'd like to access the same host value for cookie domain. Is there a way to refer to that particular variable?
Something like this maybe?
${DEFAULT_HOST}
No. There are no such default variables to access the HTTP Request Default Values.
But - you can easily achieve this using User Defined Variables.
Just create a variable DEFAULT_HOST=www.google.com
Then update the server name of the HTTP Request Defaults to ${DEFAULT_HOST}
You can also access the hostname everywhere in your test by using ${DEFAULT_HOST}.
And for extra credit...
Add a User Defined Variables element to the beginning of the test, so you can pass arguments from the commandline. In my tests, i have
name=HOST
value=${__P(host,test.mysite.com)}
Then you can use ${HOST} for HTTP and cookie defaults (and anything else), and run your test from the commandline like
jmeter -n -t mysite_loadTest.jmx -Jhost=www.mysite.com
Currently my jmeter tests have a few GET http requests. In the request, i've got data filled in the "path" field.
I'm looking for a way to randomize Jmeter so it will call an array of "paths", however i can't seem to figure this out. Anyone have any tips?
thanks!
JMeter's test element most commonly used for parametrization and data-driven testing is CSV Data Set Config
There are built-in JMeter Functions which can be used to get data from external sources
__StringFromFile
__CSVRead
There is a chooseRandom function available via JMeter Plugins
We have tried everything could someone please help us for the solution
I am sending a Get Request and getting this response {"UserID":"123456","SecurityApp":"123456"}
I want to save "UserID" content to a variable and also "SecurityApp" content to a variable and then use it in multiple POST request content
You have to use Regular Expression Extractor component of JMETER...
You will get both the UserID and SecurityApp using Regx Extractor.
and you can use those variables in subsequent requests...
There is a test element designed for extraction of data from JSON structures - JSON Path Extractor. It's available via JMeter Plugins - a set of custom extensions which make working with JMeter (and especially reporting) much more easier.
See Using the XPath Extractor in JMeter guide (scroll down to "Parsing JSON") for installation and usage instructions.
For particular your case detailed steps will be:
Download Extras with Libs Set bundle to your JMeter installation root and unpack it.
Restart JMeter if it is running - plugins are not being picked up dynamically
Add a JSON Path Extractor as a child of the request which produces that UserID/SecurityApp response
Configure it as follows:
Variable Name: anything meaningful (i.e. UserID)
JSON Path: $.UserID
Repeat step 4 but this time provide $.SecurityApp as JSONPath and SecurityApp as a Variable Name.
After Post Processor's execution you will be able to refer extracted values as ${UserID} and ${SecurityApp} wherever required in current Thread Group.
I am using JMeter and I want to access a variable set in my .bash_profile
Is there any way I can do so.
Yes. You can use Beanshell Pre Processor OR Beanshell Post Processor OR Beanshell Sampler
I tried to access JAVA_HOME, it works fine. Replace JAVA_HOME with your variable.
System.getenv("JAVA_HOME")
To access it in JMeter,
vars.put("JAVAHOME", System.getenv("JAVA_HOME"));
Then in your test use ${JAVAHOME} to get the value.
