Is there a way to update separator to read CSV file in Postman Runner. By Default is ",". But I would like to change it as ";".
Maybe there is a postman javascript reference that I could use in the pre-request script of my endpoint ?
In short, no you can't.
It wouldn't work in a pre-request script as it would have already got past the point of picking up the file data.
You can access the file data using pm.iterationData.get() but it uses that separator in the comma separated value file, to establish the variable names and the iteration values.

I have a use case where I want to read the filename from a metadata table, I have written a pipeline function to read the metadata table, but I am not sure how can I pass this information to ReadFromText as it only takes string as input, Is it possible to assign this value to ReadFromText(). Please suggest some workarounds or ideas how to achieve this, Thanks
code: pipeline | 'Read from a File' >> ReadFromText(I want to pass the file path here?,
skip_header_lines=1)
Note: There will be various folders and files in storage, files are in csv format, but in my use case I can't directly pass the storage location or filename to file path in ReadFromText. I want to read it from metadata and pass the value. Hope I am clear, Thanks
I don't understand why you need to read the metadata. If you want to read all the files inside a folder, you can just provide a blob. This solution working in python, not sure about java.
p|readfromtext("./folder/*.csv")
"*" is the blob here, which allows pipeline to read all the patterns matching .csv. You can also add something at the starting.
What you want is textio.ReadAllFromText which reads from a PCollection instead of taking a string directly.
I'd like to do a Post request in Postman where part of the JSON request body is pulled from a file like if it was an environment variable.
So something like this:
{
"field1": "value",
"field2": "{{ENV_VAR}}"
}
But instead of ENV_VAR being an actual Postman variable it's the contents of a file. Specifically an escaped XML file.
My main end goal is to be able to send an XML string as the value of one of the request body properties but I don't want to have to rebuild the escaped XML string and copy it to Postman every time I change the content of the XML file I want to send.

THis feature is not supported as of now.
The only thing you can do is to copy the content to environment varaible
you can copy content to environment variable from script as:
let xml = "<yourxml>"
pm.environment.set("ENV_VAR",xml)
you can pass content through -e flag if using newman
While working with postman, data.someVariable returns data from within a csv file that can also be used as {{someVariable}} in uri/json.
This gives us the data for that variable from that row/iteration.
Is there a mechanism to write back to the data file by doing something like postman.setData('responseCode') = responseCode.
This would be really helpful to store response code in the data file and to record call wise details in same format as the input within csv.
The only solution I figured out is
to populate json objects in the environment with information about the data file name and structure/values of information to be added
to create a separate web service (maybe in node.js) that exposes an http call to write to a file and takes in as parameter a json input as the one created in the environment as mentioned above and writes that to a file / original data file (or a copy of it) in the desired format
to call the above mentioned web service call at the end of each run or desired rest call execution to generate step wise information/debug report
There is no way to write back to data file in postman as of now .
However, you can populate that in your environment file at run time using
pm.environment.set("varname")
keep varname in such a way that you understand this is the variable you wanted to write back into data file.
I am using Jmeter as Load Test tool.
I passing one parameter through request and in response I am getting only one parameter in result. response. I want to save both request and response in csv file.
I am using Regular Expression Extractor to capture response and Bean Shell Postprocessor to save it in csv file. But not able to capture respective request param.
Example: Request : http://localhost:8080/myService?input=abcd123455
and Response : pqrst1245/84985==
While here input for request I am taking it from another csv file.
and I want to capture both input parameter and corresponding response and store it in csv file like input,response ie. abcd123455,pqrst1245/84985==
Try using this Beanshell... I didn't try it out, but it should work.
import org.apache.jmeter.services.FileServer;
if (sampleEvent.getResult() instanceof org.apache.jmeter.protocol.http.sampler.HTTPSampleResult) {
String request = (sampleEvent.getResult().getSamplerData());
String response = prev.getResponseDataAsString();
fos = new FileOutputStream("/home/user/output.csv", true);
ps = new PrintStream(fos);
StringBuilder sb = new StringBuilder();
sb.append(request).append(",").append(response).append("\n");
ps.println(sb.toString());
ps.close();
fos.close();
}
The easiest way would be using Sample Variables property. Given you have 2 variables i.e. ${request}and ${response} just add the next line to user.properties file:
sample_variables=request,response
and restart JMeter to pick the property up. Once your test will be finished you will see 2 additional columns in the .jtl results file holding ${request}and ${response} variable values.
Another way to temporarily set the property is passing it via -J command-line argument like
jmeter -Jsample_variables=request,response -n -t test.jmx -l result.jtl
See Apache JMeter Properties Customization Guide article for more information on working with JMeter properties
I would not recommend to use scripting as when it comes to high load you may experience problems with multiple threads concurrently writing into the same file and you will need to think about implementing some form of write lock
I am trying to test a webservice's performance, and having a few issues with using and passing variables. There are multiple sequential requests, which depend on some data coming from a previous response. All requests need to be encoded to base64 and placed in a SOAP envelope namespace before sending it to the endpoint. It returns and encoded response which needs to be decoded to see the xml values which need to be used for the next request. What I have done so far is:
1) Beanshell preprocessor added to first sample to encode the payload which is called from a file.
2) Regex to pull the encoded response bit from whole response.
3) Beanshell post processor to decode the response and write to a file (just in case). I have stored the decoded response in a variable 'Output' and I know this works since it writes the response to file correctly.
4) After this, I have added 4 regex extractors and tried various things such as apply to different parts, check different fields, check JMeter variable etc. However, it doesn't seem to work.
This is what my tree is looking like.
JMeter Tree
I am storing the decoded response to 'Output' variable like this and it works since it's writing to file properly:
import org.apache.commons.io.FileUtils;
import org.apache.commons.codec.binary.Base64;
String Createresponse= vars.get("Createregex");
vars.put("response",new String(Base64.decodeBase64(Createresponse.getBytes("UTF-8"))));
Output = vars.get("response");
f = new FileOutputStream("filepath/Createresponse.txt");
p = new PrintStream(f);
this.interpreter.setOut(p);
print(Output);
f.close();
And this is how I using Regex after that, I have tried different options:
Regex settings
Unfortunately though, the regex is not picking up these values from 'Output' variable. I basically need them saved so i can use ${docID} in the payload file for next request.
Any help on this is appreciated! Also happy to provide more detail if needed.
EDIT:
I had a follow up question. I am trying to run this with multiple users. I have a field ${searchuser} in my payload xml file called in the pre-processor here.
The CSV Data set above it looks like this:
However, it is not picking up the values from CSV and substituting in the payload file. Any help is appreciated!
You have 2 problems with your Regular Expression Extractor configuration:
Apply to: needs to be response
Field to check: needs to be Body, Body as a Document is being used for binary file formants like PDF or Word.
By the way, you can do Base64 decoding and encoding using __base64Decode() and __base64Encode() functions available via JMeter Plugins. The plugins in their turn can be installed in one click using Plugin Manager
