my soap/xml response looks like below:
<Account><Accountnumber>1234<Description>savings</Account><Account><Accountnumber>1235<Description>Savings1</Account>
I would like to store accountnumbers in a variable or array and would call it in another soap xml request in jmeter for knowing their details. can somebody help me how i can store and how i can call that variable ? I am new to Jmeter.
Thanks in advance.
If the account numbers are static, you're better off using a .csv file, as mentioned by Vance because the CSV data reader has less overhead then regex.
However, if you want dynamic data, it's very easy to do.
Download "regex coach" to help you write regular expressions. It's an amazing tool.
Attach a "regular expression extractor" as a child to your SOAP/XML request
Run the request once, to get the reponse
Copy the response into regex coach (or whatever tool you use), and write your regex. It'll look something like this: (\d+?)\D (look for any digit after the text accountNumber and stop after a non-digit)
Configure the rest of the regex. In this case, you'll want:
Apply to: Main Sample Only
Response filed to check: Main Body
Reference Name: VariableName
Regular Expression: See step 3
Match No: 1 (1st match) 0 (any match) or -1 (all
matches, useful when doing "FOR EACH
found" logic
Default Value: failed
TO use your variable account number in other requests, simply use the reference name. In this example: ${VariableName}
Reference: http://jmeter.apache.org/usermanual/component_reference.html#Regular_Expression_Extractor
You may save your data in a ".csv" file and Jmeter can read it easily through its csv data set config.
Use ${your data variable} in your scripts.

I'm capturing multiple values with a regular expression, and that expression returns 20 matches as shown in image RegExMatches,
My regular expression is something like this RegEx.
How do I use multiple values in post data of my HTTP request which is something like PostData
I tried with MatchNR and -1 and call with ${candidateGUID_gN} N being the match number but this didn't workout.
How do I use the Extracted values in Post data ? or will I have to make different Regular Expressions for each value ?
I think the only way of achieving this is building your request using JSR223 PreProcessor and Groovy language, take a look at the following JMeter API shorthands:
Arguments
vars aka JMeterVariables
sampler aka HTTPSamplerBase

From a csv file, I need to pass
224,329,429
as a single value to one of the parameter in HTTP request.
I have parameterized using CSV data config. But, only 224 is getting passed.
I want 224,329,429 to be treated as a single value.
Please let me know how do I achieve this. Should I change anything in CSV config or CSV file to make this work?
Just use __StringFromFile() function instead of using CSV Data Set Config.
The __StringFromFile() function reads next line from the file each time it's being called so it seems to be a lot easier to stick to it for particular your scenario.
The syntax is as simple as ${__StringFromFile(/path/to/your/file.csv,,,)} and the function can be used anywhere in the script, i.e. directly in the request parameter section.
See Apache JMeter Functions - An Introduction to get started with the JMeter Functions concept and comprehensive information on the above and other JMeter functions.
You should change your delimiter to a not used character e.g. #
In that way you will be able to get full line for every request
Use ${__FileToString(dummy.csv,,payloadvar)} function. It makes the file independent that mean you can use any file extension example: .txt, .csv, .excel etc..
Just keep the string in dummy.csv and it will fetch the whole string.
benefit of using this function is, it will not consider comma's so in case your string has comma separated values then this is the best option.
Just use %2C in the place of comma.
How can I extract the response using a regular expression for Jmeter.
Jmeter is not extracting the response item that I want to extract. I've tried several times, but I failed. How can I extract the response item?
Response data is as shown in the screenshot:
The value which I need to extract has been highlighted.
I tried extracting using the following expression, but it failed:
<h2>.+?<a hfref="http://(.+?)">.+?</a>.</h2>
Please follow the below steps to extract the Id value.
In your Regular Expression Extractor, configure below details. Use the regular expression as Public/FormsPreview.aspx\?Id\=(.+?)& to retrieve the Id.
You can use other unique left/right boundaries as well, as your regular expression.
How to validate your regular expression extractor?
To validate your regular expression extractor, add a Debug Sampler (Right Click on your thread group > Add > Sampler > Debug Sampler)
Execute the test plan
In View Results Tree you can see the c_ID value as shown below.
Depending on how vary can result be (I mean, how the form is changing? is that only querystring Id parameter that is different? could there be another response (than Object Moved) with Id that you don't want to parse? etc.), the regular expression in the Regular Expession Extractor Post-Processor (which fits best here) would be different.
From simplest context-agnostic, Id=(\d+) (that is considering you have numeric Id), to making it case-insensitive (?i)Id=(\d+) and/or alphanumeric Id=([0-9a-zA-Z]+), or even whatever symbols are in (but you'd be forced to start to include context in this case ) Id=(.+?)& - and up to one that uses broader context evaluating the whole multiline stuff, like (?im)<title>Object\smoved</title>.+<a\shref=.+Id=(\d+)
And don't forget to use $1$ as your Template and take the Match 1.
I suggest you to stick to the most narrow and most context-agnostic one you can afford (the very first example here).
Add some assertions to make sure you're on the right page - despite the fact they executed after post-processors, you'd see something is wrong, at least.
You can add regular expression extractor like following
How to pass jmeter response data (ex: getting response 295 without any lable) to next http request url path/body. This 3 digits/4 digits number is dynamically generated for every run and this value i have to use it for next API calls. Since this value is not having any lable/attribute name not sure how to extract this value. Please suggest.
Regular Expression Configuration:
Reference Name: anything
Regular Expression: (.+)
Template: $1$
Match No.(O for Random): 1
The Reference name should be passed as the variable in the next HTTP request URL path/body.
Screenshot from Regex Test in View Results Tree.
If you need to extract a single numeric value, the relevant regular expression will be as simple as (\d+). See Perl 5 Regex Cheat sheet for quick reference.
If in future you will need a regular expression which return the whole response (including line breaks, special characters, whatever), as per How to Extract Data From Files With JMeter article it will be something like (?s)(^.*)
Using JMeter to support functional API testing and have run across a problem with reading data from a CSV file. The data from the file is used in building a POST data body which contains something like this:
"wibbles" : ${wibble-var},
${wibble-var} is read from a CSV file and has the format :
["wibble1","wibble2","wibble3"]
... there are over 1000 wibble values in the list.
If "wibbles" : ["wibble1","wibble2","wibble3"]... is hard-coded into the POST body, then JMeter is happy, builds the POST request and does the business, but it's proved impossible to create a CSV file with even the 3 value example above, that JMeter will parse. JMeter skips the thread containing the 'CSV read' without building the POST request or sending it, so there's no response to examine, and a Debug Sampler is similarly skipped. I've heard rumours that doubling up the quotes can work but haven't been able to find the right syntax. Can anyone throw any light on this issue? Thanks
Double quotes will work if you can get "wibble1,wibble2,wibble3" & if you set Allow quoted data to true in CSV data set config
You can get this value and then use beanshell preprocessor to convert to the format "wibble1","wibble2","wibble3".
If you want to get in this format "wibble1","wibble2","wibble3" directly, you can use \t as the delimiter & modify the data in the CSV file accordingly.
Trial and error led to the following solution.
The format of the single data variable I needed to parse is ["value1","value2","value3"] (i.e a JSON array.) and this is exactly what the CSV file contained (with a header name of course on the first row), including the [ and ] brackets.
I modified the parameterised POST body to:
"wibbles": [${wibble-var}],
-- that is, I moved the square brackets out of the CSV file so that the CSV file now just contained the quoted elements of the array:
"value1","value2","value3" etc
I then set the delimiter in the CSV Data Set Config to |
And Allow Quoted Data to FALSE. <--- This was a bit counter intuitive but without it JMeter would not read the whole comma separated list of 2000 quoted strings as a single variable.
With these changes in place the script executed correctly.
Thanks again for the responses, I will definitely look at the __String functions mentioned.
I would go for the following options:
If your "wibbles" are a single string which you need to pass a a JSON Array it might be a lot easier to access them via __StringFromFile() or __FileToString() functions like:
"wibbles" : ${_StringFromFile(/path/to/file/containing/wibbles,,,)},
If you need to access individual "wibbles" and your CSV file is basically a JSON file:
Add HTTP Request Sampler to your test plan (before one which sends these "wibbles") and configure it as follows:
Protocol: file
Path: c:/testdata/yourfile.csv
Add JSON Path PostProcessor and use a JSON Path query to store the "wibbles" into a JMeter Variable(s)
