I'm new to Jmeter and need some guide. I'm trying to read in a lot images from a directory and need to convert each picture to base64 in Jmeter. If I understand correct, in the HTTP request I can use __FileToString. However, I need convert it first and then pass to the request.
I have tried using ForController and converting as described on the Internet with BeanShell Sampler, but the image comes out corrupted. Could you please direct me how to do it ? Thanks.
I've heard Groovy is the new black, moreover you should not be using Beanshell since JMeter 3.1
So you can convert an image into its Base64 representation using __groovy() function like:
${__groovy(new File('/path/to/your/image.png').bytes.encodeBase64().toString(),)}

I need to extract a value from http response which is in the
format "test/23|temp value"
and need to pass it in next request string body as "test%2F%7Ctemp+value"
I believe we are doing some form of encoding. how can we achieve this in JMeter ?
Appreciate if any one can help.
Take a look at __urlencode() function
${__urlencode(test/23|temp value)}
it does percent-encoding of the input and returns the result in the place where it's called in the runtime:

I have a POST data from CSV used in excel
{"Name":"","Token":-1,"TimeScheduleToken":"1","AccessRule":[{"ObjectToken":"528","ObjectName":"Common_ wash_Room_Exit","RuleToken":"528","RuleType":2,"StartDate":null,"EndDate":null,"ArmingRightsId":null,"ControlModeId":null}]}
When performing a post-execution the JSON data in the request is not as same as from the CSV. Find the request in the image
Quotes given for the key value pair is doubled up and showed in the request. How to resolve this, kindly suggest
Vittal,
I have tried to reproduce your issue in JMeter 3.3 and noticed that its working fine. Please find below the settings that you need to do in 'CSV Data Config' element.
Moreover, I would recommend that when you are creating any csv file for the data then open the notepad and enter your data and then save it as .csv file to avoid any unnecessary elements/characters in the data.
You can also refer to the blog post to get more information on API load testing using JMeter: JMeter Load Testing Against APIs
I have no idea regarding how you're getting these double quotation marks, however here is how you can remove them in the runtime:
Add JSR223 PreProcessor as a child of the HTTP Request sampler
Put the following code into "Script" area:
def originalData = sampler.getArguments().getArgument(0).getValue()
def normalizedData = originalData.replaceAll("\"\"","\"")
sampler.getArguments().removeAllArguments()
sampler.addNonEncodedArgument("",normalizedData,"")
sampler.setPostBodyRaw(true)
That's it, the JSR223 PreProcessor will replace all occurrences of double quotation marks with single quotation marks.
sampler is a shorthand to parent sampler class implementation, in case of HTTP Request sampler it would be HTTPSamplerProxy, see class documentation for all available functions and properties.
See Apache Groovy - Why and How You Should Use It article to learn more about using Groovy scripting in JMeter tests.

Could you please help me in solving this issue with some screenshots
I got few tips on how to use Beanshell pre processor but its not helping me or im not sure how to implement beanshell to mitigate the issue.
Note: I am using content encoding as utf-8
Take a look at __unescapeHtml() function, it can decode HTML-encoded strings on-the-fly
You can use this function directly in the HTTP Request sampler body or wherever else.
See How to Use JMeter Functions posts series for more information on JMeter Functions, how they can be used, what are limitations, etc.
This is what I did to mitigate the issue. hope it helps for the newbees (Big thanks to Dmitri Tikhanski)
The above token is SAML 1.1 token that is generated as the response to a GET method. If your using ADFS authentication you will get a big HTML in which you will have - WA, Wresult, Wctx. (for me only wresult(SAML 1.1 token) which was a correlation candidate)
Extract the wresult as following using RegularExpression Extractor.
enter image description here
and the captured Wresult to be replaced in /v2/wsfederation with the function __unescapeHtml.
enter image description here
Note: 1) Wa result in my case its not dynamic
2) wctx string is a static string.
Hope this helps. thanks.
In jMeter How to get multi part body in BeanShell PreProcessor
I need to get the image data and post parameters
by using sampler.getArguments(); I am able to get the post parameters but not the image file
Please help me
You can use getHTTPFiles method of Sampler API.
sampler.getHTTPFiles() will return the file path HTTPFileArg in an array through which you can update new file at run time.
Update:
String path = sampler.getHTTPFiles()[0].getPath();
byte[] array = Files.readAllBytes(new File(path).toPath());
Something like:
File image = new File(sampler.getHTTPFiles()[0].getPath());
//do what you need with the image file
If you need extended image information take a look at ImageIO. For more Beanshell tips and tricks check out How to Use BeanShell: JMeter's Favorite Built-in Component
I have used BSF Postprocessor to parse json in one of my jmeter test files. My code is as follow.
eval('var response = '+prev.getResponseDataAsString());
vars.put("userAccountID", response.ID);
But i have found that BSF post processor reduces Jmeter's performance. So i am going for JSR223 Post processor. I need to know what is the corresponding code for above in JSR223 (JAVA language). Thanks in advance;
I suggest to use jsr223 assertion and javascript. Then you can just simply check and parse your data. for example:
var response = SampleResult.getResponseDataAsString();
var jsonOutput = JSON.parse(response);
Now you can simply operate on "jsonOutput".
#UPDATE#
Looks like in new JMeter version using javascript is deprecated because of performance and lack of options to manipulate data.
(Back then when i was test developer my example had been working just fine; thats why i show it here)
Probably better option is to migrate to Groovy:
http://michalsi.github.io/performance-tests/2018/01/08/jmter-working-with-json.html
There is no out-of-box support of JSON in Java SE hence sample code will depend on JSON library for Java you choose.
May I suggest take a look at JSON Path Extractor Post Processor instead? It is designed to parse JSON data and doesn't require any scripting.
For more information on the JSON Path Extractor see Using the XPath Extractor in JMeter guide (scroll down to "Parsing JSON" section)
