I am trying to test our API on WS using WebSocket Sampler(Maciej Zaleski)
I want to extract the response from the first API and store the matched pattern as
variable, then pass it to the next request
But I failed and failed again on getting empty result
To extract by regular expression you need to find a group,
Group is found using () which you are missing.
In your case use Regular Expression: FH(\d{5}-\d{7})
Also you need to provide Template,in your case for first group, use $1$

I'm trying to get assert a response body from a list of objects that were deleted with AWS SDK, the scenario is this:
I use a Delete Http request to a endpoint passing an array, with a list of object names, then aws should return the list with the objects that were deleted, but it's not in the same order of the list that i've passed, so i'm using a Contains to see if the objects are in the response body.
Someone can help me? I think that is a problem with Regex from JMeter but I'm freeze with this.
You're using Contains pattern matching rule which expects the pattern to be a Perl-5 compatible regular expression
In this case you will need to properly escape all the meta characters either manually or using a __groovy() function calling Pattern.quote() method instead:
${__groovy(java.util.regex.Pattern.quote(vars.get('listOfObjects')),)}
If you want to check whether the response just contains your ${listOfObjects} variable switch to Substring pattern matching rule
I am testing rest API using Jmeter. In one scenario need to pass complete response of a http sampler to, another http sampler as a request dynamically. Any suggestions how to achieve this in Jmeter.
Add Regular Expression Extractor as a child of the request which response data you want to capture
Configure it as follows:
Name of created variable: anything meaningful, i.e. response
Regular Expression: (?s)(^.*)
Template: $1$
That's it, you should be able to refer the extracted value as ${response} where required.
Explanation of the regular expression:
() - grouping
(?s) - single line modifier
^ - line start
. - wild card character
* - repetition

How to Extract Data From Files With JMeter
You can get all response using Regular Expression Extractor with regex accepting all characters
In next JMeter 5.2 version you will able to do it using Boundary Extractor by keeping Left and Right Boundary empty
In my application while executing the first request one unique key is generated which key is required for Next all the request. let me how to automate such scenario in Jmeter.
The process should look as follows:
Add Post Processor to the first request
Configure it to extract the required value and store it into a JMeter Variable
Use JMeter Variable from step 2 in your next request.
Depending on response data type you have the following choices:
Regular Expression Extractor - for text
CSS/JQuery Extractor - for HTML
XPath Extractor - for XML and XHTML
JSON Path Extractor - for JSON
It is also possible to extract data from files i.e. if response is in PDF format, but it's a little bit tricky
Example configuration to store the whole response:
Reference Name: any suitable variable name, i.e. response
Regular Expression: (?s)(^.*)
Template: $1$
You can refer the extracted value as ${response} where required. You can also amend the regular expression to extract response part instead of the whole response. JMeter uses Perl5-compatible regular expressions, see Regular Expressions User Manual Chapter for details
You can use regular expression extractor to extract the key from the response of your first request and use the extracted key for subsequent requests. To achieve this:
Right click on the first request and add post processor: Regular Expression Extractor.
Create your regular expression and provide values in other required fields. Please refer to JMeter component reference http://jmeter.apache.org/usermanual/component_reference.html#Regular_Expression_Extractor
Extracted value will be saved in the variable given as reference name
Use this variable in subsequent requests
Here is an example test plan with results.
I have the following json response from HTTP sampler
{
url: "https://example.com/ir/rest/wsVerRest/getFile?filePath=/data/IR/data/IR_Org/user.mail#abc.com/testSample1_testSample2/testSample1_20151201214307897/outputs/CnvActor-00/testCoverage1.seg",
},
{
url: "https://example.com/ir/rest/wsVerRest/getFile?filePath=/data/IR/data/IR_Org/user.mail#abc.com/testSample1_testSample2/testSample1_20151201214307897/outputs/CnvActor-00/testCoverage2.seg",}...{testCoverageN.seg}
From these I have to construct another htto sampler by using the server(ie xyz.itw),url(/ir/rest/wsVerRest/getFile),keyparam(filePath),value(/data/IR/data/IR_Org/user.mail#abc.com/testSample1_testSample2/testSample1_20151201214307897/outputs/CnvActor-00/testCoverage2.seg)
How to get these values using regular expression extractor and use in another sampler.
At present I can use regex to get those values.but don't know how to use in another http sampler.Please help.Thanks

If you are able to get these values via Reg Expression extractor then it will not be a problem for you. When you use Regular expression extractor then the value are stored in "Reference Name" that you mentioned in your Extractor.
Lets say, your reference names were like below:
ServerValue
UrlValue
KeyParamValue
and so on..
you can simply use them like this in your intended HTTP sampler..
${ServerValue}${UrlValue}${KeyParamValue}
I am testing a site using JMeter. I am creating a GET request for getting an account number by an unique id. Which returns only the account number(in String). How can I get the account number in to a Reference Name of JMeter extractor?
Use Regular Expression Extractor.
Add Regular expression extractor (under Post Processors) as a child of your request. Provide Reference Name of your choice. Provide Regular expression as (.+?).
As you say the response has only the Account Number you are looking for,
Use a Beanshell post processor,
vars.put("ACCOUNTNUMBER", prev.getResponseDataAsString());
Then you can use ${ACCOUNTNUMBER} , in your test to get the value.
