how to generate unique ids in jmeter
I am a newbie. I am using JMeter to test registration form based software.
Here's my scenario:
A user logs in and adds a patient in database. I am able to automate this
process by recording it, however I want to automate the add patient
scenario, since a unique patient id is required to add a patient and save it
on the database. The procedure I am following right now is manually entering
ids and then running the automated script, which is not putting any load or
stress on the site.
If somebody could please tell me how to generate unique ids and how to fit
this procedure in already working script or how to increment previous id
whenever the script is run.

Re: how to generate unique ids in jmeter
Posted by Rodolfo Landa <ro...@gmail.com>.
I had a similar requirement:
In my test plan an http request was being called like this:
/myurl/a/b/c/trackid=abcd-efgh
Where abcd and efgh are unique numbers for each User (Thread) / Loop.
I added a User Parameters control before calling this http request like
this:
Name 1: id_first
User_1: ${__Random(1,1000,ID_FIRST)}
Name 2: id_second
User_2: ${__Random(2001,3000,ID_SECOND)}
Then I replace these variables in the original http request like this:
/myurl/a/b/c/trackid=${ID_FIRST}-${ID_SECOND}
Notes:
a) I checked the option Update Once Per Iteration in the User Parameters
control
b) My test plan has other http request that need the same calculated track
id for that User / Loop.
b) I first used id_first and id_second but every time I call them in other
http request the random numbers are re-calculated. Using ID_FIRST and
ID_SECOND solved that problem for me.
I hope this is similar to your problem and can help you.

Rodolfo

Re: how to generate unique ids in jmeter
Posted by virkenator <vi...@gmail.com>.
Hi,
I totally agree with you that, to generate a random value is more beneficial
than incrementing the previous one.
My application can handle any type of string. If you could please help me
figure out, how to create/generate random values and how to append them in
the script, I would highly appreciate.

Re: how to generate unique ids in jmeter
Posted by Deepak Shetty <sh...@gmail.com>.
Hi
Either you use an incremented variable in which case you will have to
maintain what was the last used value (or atleast retrieve it) or you can
use any random value (So long as it is unique), the latter is easier because
you dont need to care about the previously used values (or even running it
across multiple machines), any new value is always unique (however by
nature these are strings and your application may not be able to handle
strings). So the question is can your application handle any unique string
or not?
If you need to use a numeric value then use a counter as mentioned
previously. How you get the value to add the counter to depends on your app.
You can do this outside of JMeter and pass it to Jmeter as a property , you
can have a setup thread group in Jmeter which for e.g. reads from a database
the max value and sets that into a property or you can read the value from a
file and at the end of the test update that file
If you have to distribute the test across machines then auto increment will
be tougher to manage.

Re: how to generate unique ids in jmeter
Posted by virkenator <vi...@gmail.com>.
No, not a token but an incremented value for the field, so that i dont have
to increment it manually. Because once the script is run, it can not be
re-run with same value for the field.
That ways, the script will add patients automatically depending on the
number of loops specified.
I hope, I am understandable.

so you actually want an incremented numeric field only? Not a unique token ?

Re: how to generate unique ids in jmeter
Posted by virkenator <vi...@gmail.com>.
Hello Deepak,
Thank you replying.
Patient t ID is a mandatory field in the form, and it has to be
unique/different from IDs already entered/existing in the form database,
that is why user has to specify id every time he/she wants to save the form
and if it is not different/unique from already existing one, the form will
not get saved.
However, the script will run just fine.

Re: how to generate unique ids in jmeter
Posted by Deepak Shetty <sh...@gmail.com>.
First i dont quite think your description is accurate since Id find it hard
to believe that your application asks the user who's entering information
into the form to generate the unique Id. So if I access your application in
a browser do i have to enter a unique patient id?
For the moment Assuming that your problem is what you state it is
Thread Group
+Req1
+Req2
+Req3 (specify the below as name/value)
++patientId Patient_${__threadNum()}_${currentTime}
++ other parameters
+Req4
+User Parameters ( update once per iteration checked with the following
variable)
++currentTime ${__time(YMD)}${__time(HMS)
Then add a view results tree listener , and in the request tab you can see
that you are posting unique values for patientId every time
Your test may still not work , but the problem wont be the generation of
unique value.
If you want an autoincrementing scheme then you need to use
http://jakarta.apache.org/jmeter/usermanual/component_reference.html#Counterplus
beanshell to track the last used counter number from a previous test
run or you can code it in beanshell/java

Re: how to generate unique ids in jmeter
Posted by virkenator <vi...@gmail.com>.
Hi Deepak,
Thank you for the help. I tried it, but in vain. May be I need to explain
you more details. When I create a patient, that data needs to be posted
through the HTTP request to the server.
Here is how my script works.
1. A user logs in
2. Goes to the patient registration form.
3. Adds patient id, which has to be unique every time patient needs to be
added.
4. Saves the form and logs out.
This script has all the HTTP requests. During the step 3, there are two
fields(patient id and patientkey) which need to be edited (which I am
presently editing manually) and posted as the HTTP request for step 3.
I am wondering is there any way, I can increment or create unique values for
these two fields and then POST them as a HTTP request automatically.

Re: how to generate unique ids in jmeter
Posted by Deepak Shetty <sh...@gmail.com>.
This is one way
add a User Parameters , just one user will do, specify the name like
currentTime and value like ${__time(YMD)}${__time(HMS) . Also check update
once per iteration (basically generating a timestamp , you can use other
ways to generate a timestamp too , the reason I do it this way is that I
need this value for multiple samplers)
Then when you need to post a unique data element, you can provide a value
like
${userIdPrefix}_${__threadNum()}_${currentTime}
where userIdPrefix is a variable normally defined as JMeterCreatedUser or
something .
Note that because JMeter can call javascript or even Java/BSH any method you
want of generating unique ids works (for example you could use UUID's)
