Compare Assertion in Jmeter - validation

I am new to J meter. Please look into the following body data in Http request
{
"groupBy":"${groupBy}",
"offset":0,
"limit":10
}
I need to check whether limit value is above 10 in the above content. Is it can be done by using Compare Assertion.
Thanks in advance.

You have to extract the value "10" in to variable using "Regular Expression Extractor" after that use "Response Assertion" by choosing "Jmeter Variable" option under "Apply to" choosing "Equals" option under "Pattern Matching Rules"
and add 10 under "Pattern to test"

There is a special Test Element - JSON Path Assertion available via JMeter Plugins which is designed for working with JSON data.
The relevant JSON Path expression to match your "limit" will be as simple as:
$.limit
Try to avoid Compare Assertion where possible as it consumes very much resources.

How to correlate different values in a RegEx with multiple matches with JMeter- Correlation Recorder?

I have a problem in JMeter that I can't figure out how to solve.
Situation:
I want to load test an ASP.NET-website.
bzm - Correlation Recorder used for recording and correlation
ScriptResource and WebResource have multiple occurrences
Now I used following RegEx to extract the ScriptResource values: <script src="(.+/ScriptResource.+?)". Then I stored the 3 matched values into 3 different variables. But I can't replace the values in the found order.
Example:
First Match: stored in : AspNet_ScriptResource
Second match stored in: AspNet_ScriptResource_1
Third match stored in: AspNet_ScriptResource_2
The three matches have all different values, can't paste one value into all 3 matches.
So I have to write the value from AspNet_ScriptResource into the first match (matchNr=1).
AspNet_ScriptResource_1 into second match (matchNr = 2) and
AspNet_ScriptResource_2 into third match (matchNr = 3).
But in the Correlation Rules (in the Correlation Recorder) in the "Correlation Replacement" section, there is no option to choose in which matchNr to write.
Correlation Recorder: Correlation Rules
I tried to use a BeanShell Preprocessor with a for-loop but I only found a way to write in the logs, not in the response body.
Is there a way to solve this with the Correlation Recorder plugin? If not, what options do I have to handle such a scenario?
Thanks for your help! :)
You can raise an enhancement request for the bzm - Correlation Recorder via JMeter Plugins support forum or if you're a BlazeMeter customer and need this piece of functionality asap - you can open a support ticket for implementation of the feature.
Currently it seems that the Correlation Recorder expects you to provide a regular expression either with the unique match or you will have multiple substitutions with the same value.
With regards to Beanshell approach:
You can substitute response data, but not with the PreProcessor, you need to do this via the PostProcessor using prev.setResponseData() function
Since JMeter 3.1 you're supposed to be using JSR223 Test Elements and Groovy language for scripting
If you need to change request data, not the response data, you can do this via sampler.getArguments() function

Jmeter- Condition using response assertion

How to put a condition using response assertion in jmeter.
In loadrunner we have web_reg_find with savecount attribute. This helps us to for keeping condition in IF loop.
if textcount >0
transaction --> pass
else
transaction--> fail and exit iteration and continue
Similarly, how to get the count of text check and place the same in condition (IF loop) in jmeter.
Use any of the post processor extractor to fetch all the values in a variable. Like in regular expression we can use "-1" in "match no." to fetch all the values matching with the regular expression. So, you will get the count.
Now, put that as a condition in if controller like ${__groovy("${countVar}"=="10")}
In short,
1.Add a Regular Expression Extractor as a child of the request to fetch all values.
2.Add If Controller at the same level to check the condition.
More information: 6 Tips for JMeter If Controller Usage
If you provide "Match No" as -1 in the Regular Expression Extractor
you will have ${foo_matchNr} variable containing the number of matches.
Since JMeter 4.0 you have __isVarDefined() function which can be used to check whether a JMeter Variable is defined or not
Both approaches can be used in the If Controller

SoapUI XPath assertion - wildcard string with Excel dataSource

I want to use an assertion "expected result" that uses both some form of "contains" function or wildcard AND gets the text to test against from an Excel dataSource. The SoapUI 'contains' function has no way to use a dataSource that I've found, and I cannot figure out how to use an XPath function like contains with a dataSource. Can someone please explain how that works?
--
I've been asked for more detail.
In SoapUI, if I add an assertion and choose the request/response as the source, I then have a choice of assertions. One of them is "XPath Match". I can use that to designate a specific field in the response, in this case, which value I want to test.
Having chosen the "XPath expression" in the top half of the "XPath Match Configuration", I can then choose my Excel dataSource as the content for the lower half "Expected Result". I have used this to test an error code against an error code from the Excel spreadsheet.
What I don't know how to do is determine, in this assertion, that the error message returned contains the value in Excel. I figure something special goes into "Expected Result" in the "XPath Match Configuration" box, but I don't know what.
The Expected Result of the XPath assertion is only a "dumb" string. The best that you can do in this field is property expansion ... which does not help your cause.
Instead you will need to use the top portion, where you can enter XPath Expression, that provides the logic you are looking for. Your XPath expression will need to look something like:
contains(//*:some/*:node, '${data_source#property}')
and your Expected Value will be simply:
true
Convenient reference, in case you need it.

JMeter does not replace ${SUBPANEL_RELATE_MODULE_g1} with its value

It's a long story, but I will try make it simple:
I generated MeterMaid XML files with SugarMMM; I chose only the Accounts module:
I converted above files to JMeter format with MeterMaid (I consolidated the tests into one file and named it "filename.xml"):
ruby GenMeter.rb --inputfile=filename.xml --outputfile=filename.jmx
I did the necessary CSV setup. All the CSV file contains is the login details (usr,pwd) for testing concurrent user logins. This part works well indeed.
When I run the test, I can see that a whole bunch of ${} variables are converted into corresponding values. Sadly, ${SUBPANEL_RELATE_MODULE_g1} doesn't get resolved... here's what the GET url (from View Results Tree Listener component) looks like:
http://localhost/sugarcrm/index.php?module=${SUBPANEL_RELATE_MODULE_g1}&action=Popup&hide_clear_button=true&mode=MultiSelect&create=true&metadata=undefined
Note that it's not the only variable that isn't resolved. The following screenshot shows the other tests that fail, all also caused by other variables not replaced by their corresponding values:
Here's how this variable is set up (which is well before the time it's used):

Verify in your CSV dataset config, all variables are declared correctly (no typos, no omissions, no spaces before variable names, etc.)
I would also suggest putting a debug sampler high in your tree, as it will show you every variable and its value and can save a lot of time.
Edit:
It looks like your regex is setup incorrectly for creating multiple groups. If you look in your Debug sampler, you have SUBPANEL_RELATE_MODULE=Accounts but not SUBPANEL_RELATE_MODULE_g1= . This implies you don't have GROUPS setup.
In looking at your regex, the line template: $0$ is saying "only give me one group", whereas it looks like you want 4. Thus, you should try template: $1$$2$$3$$4$ the first match should be _g1 the second _g2 and so on. Check out the manual for details.
make judicious use of the ${SUBPANEL_RELATE_MODULE_g1} variable throughout the script after it gets defined by the Regular Expression Extractor. Verify it exists. Use it in Controller titles, test headings, at the beginning of tests, and at the end of tests.
That will help narrow it down
This way you can follow it along in the script to make sure it exists just before the moment it is used, and find where it's breaking down. Basically print statement debugging.
I don't know about sugar CRM or metermaid but for jmeter I had a similar problem with variable that were not resolve.
Check if this variable is declared somewhere or maybe you need to write a reg ex to extract that value from the previous request.
The problem I got It was that I extracted the variable from a CSV files
the variable name was CONTRACTNO, CLIENTNO
my URL : /SomeURL/bla?eventId=contractSelected&contractNoSelected=${CONTRACTNO}&applicationID=BLa
And it wasn't working so I changed the variable name in the csv file to :
CONTRACTNO,CLIENTNO (look that I removed a space)
Jmeter tend to be very picky with space in name and variable definition.
You are expecting the following values
${SUBPANEL_RELATE_MODULE_g1}
but you have configured the Regular Expression Extractor reference name as
"SUBPANEL_RELATE_MODULE"
There two options you can get the values
You have to change the ${SUBPANEL_RELATE_MODULE_g1} into ${SUBPANEL_RELATE_MODULE}
You have to change the Regular Expression Extractor reference name as "SUBPANEL_RELATE_MODULE _g1" to "SUBPANEL_RELATE_MODULE"
After this your values will be replaced properly.
It looks like your regular expression isn't picking up a match, your default value is set to "Accounts" and in your debug output that's the value of the variable. You'll only get match groups if the regular expression matches.
The View Results Tree listener now has a RegExp tester, so you can go to the request that you're trying to extract the variable SUBPANEL_RELATE_MODULE from the result in the results tree and choose RegExp Tester from the dropdown where it says "Text".
You can then run your regular expression on the response data in the RegExp tester and probably find that it doesn't match and then hone your regular expression so that it matches and update it in your Regular Expression Extractor.

How to compare the responses from two different servers using Jmeter?

I need to compare the responses from two different servers using Jmeter. I think that Comparison assertion in Jmeter supports the response comparison. But how to use this? What is the purpose of 'Comparison filters'?
You'll need the Assertion as a parent or sibling to your compare requests. Make sure you add the Listener "Comparison Assertion Visualizer" to help see the differences/debug
The Filters are to remove strings you know are dynamic, for example a timestamp or unique userID embedded in the response. It uses PERL regular expressions, the same as the post-processor Regex Extractor
Here's a sample structure:
Test Plan
+ Thread Group
+ Server 1
+ Server 2
+ Compare Assertion
+ Compare Assertion Visualizer
