How to upload image through JMeter? - testing

I have a website which needs to upload multiple images at a time. So I want to know what is the process of posting image file through JMeter?

You'll need the following:
In HTTP Request Sampler:
Select "POST" method from drop-down.
Check "Use multipart/form-data for POST" box
Provide correct input name, MIME type and path for the file to be uploaded.
See Upload and Download Scenarios with Apache JMeter guide for more details.

If you need to upload multiple images best option is to go for a CSV Data Set Config element in Jmeter.
First, add the full path of the images you want to upload comma separately in a file (.csv) as below.
eg: D:\User\Images\img1.png,D:\User\Images\img2.png
Then, add a CSV Data Set Config element most preferably to the top of the script
Next, configure the below elements in the CSV Data Set Config element
Filename: full path to the csv file
Variable names: “column name” in the csv file if you have added one or any variable name if you don't have a column name (eg: images)
Note: Make sure to change the delimiter and other optional parameters as required.
Finally, in a HTTP Request you can use the parameter ${images} to call the images. The CSV Data Set Config element will read the image names from the CSV file and set them in the variable called "images".
Refer the below guide for more information.

How to parameterize values in the csv file which is already parameterized in Jmeter

I have multiple API request bodies and Im passing them using txt file in CSV Data Set Config. This API request bodies have certain values to parameterize. How Do I acheive this? something like paramertize inside parameterized csv file.
If your CSV file contains JMeter Functions or Variables which you want to evaluate in the runtime you need to wrap the variable(s) defined in the CSV Data Set Config into __eval() function
For example if you have:
test.csv file with the single line containing ${foo} and CSV Data Set Config reading this file into some-variable
User Defined Variables which assigns the variable foo the value of bar
And a couple of Debug Samplers for visualization
You will see that:
${some-variable} will return ${foo}, basically the line from the CSV file
${__eval(${some-variable})} will return bar because the variable will be evaluated and its respective value will be resolved.

JMeter - testing unique links taken from CSV file

I want to test unique link taken from csv file in Jmeter. I have a csv file with unique values - "value 1", "value 2" .....
For each thread, I need to append it as part of url(or path).
Ex: BaseURL: example.com
For thread 1, example.com/value1
For thread2, example.com/value2
How can I do this in JMeter? Any help will be highly appreciated. I have created CSV and all. Just need to know how to take that value and set as part of path.
Put your "base url" into "Server name or IP" tab of the HTTP Request Defaults:
Configure CSV Data Set Config to read the values from the file and store them into a JMeter Variable
Use the variable from the step 2 in "Path" field of the HTTP Request sampler:
That should be it, each thread will read the next value from the CSV file on each iteration:
Demo:
In CSV Data Set Config add path as Variables Names, use Sharing mode All Threads
In HTTP Request Path field add ${path}
Each thread will send a different path taken from CSV line

NiFi data insertion into s3 subdirectory

I have a flow where I am extracting data from the database, converting the Avro to the CSV format and pushing the CSV in an s3 bucket which has subfolder in it. My S3 structure is like the following:
As you can see in the above screenshot my files are going into a blank folder(highlighted by red) instead of going inside a subfolder called 'Thermal'. Please see my PutS3Object settings:
The final s3 path I want my files to go into is: export-csv-vehicle-telemetry/vin11/Thermal
What settings should I change in my processor so the file goes directly inside the 'Thermal' folder?
Use Bucket name as: export-csv-vehicle-telemetry/vin15/Thermal instead of export-csv-vehicle-telemetry/vin15/Thermal/
The extra slash at the end is not required while specifying bucket names.
BTW, Your image shows vin11 directory instead of vin15. Check if that is correct.

Upload csv files with comma inside it

As per my requirement, I need to upload a .csv file into the application. I am trying to simulate this using loadrunner. The issue I am encoutering is that my csv file is in the below format
Header - AA,BB,CC
Data-xyz,"yyx,zzy",xxz
On using the below statement to upload the file, I am getting an error ""line 2 contains 4 columns instead of 3"
web_submit_data("upload",
"Action=xxx/upload",
"Method=POST",
"EncType=multipart/form-data",
"RecContentType=text/html",
"Referer=xxx",
"Snapshot=t86.inf",
"Mode=HTML",
ITEMDATA,
"Name=utf8", "Value=✓", ENDITEM,
"Name=token", "Value={token_1}", ENDITEM,
"Name=upload_file", "Value={NewParam_5}", "File=yes", "ContentType=text/csv", ENDITEM,
"Name=Button1", "Value=Upload", ENDITEM,
LAST);
AS per information provided in How to deal with a string with comma in it from a csv, when we have to read the data by using loadrunner? ,
I tried updating the .prm file to a new delimiter pipe, | but still i get the error.
[parameter:NewParam_5]
Delimiter="|"
ParamName="NewParam_5"
TableLocation="C:\temp"
ColumnName="Col 1"
I also notice that even though I set the delimiter to pipe, if I rightclick on the web_submit_data() and go to Parameter properties, i see a column delimiter option there as well and it is not set to pipe and is set to comma which indicates that this setting is taking higher precedence to the setting in .prm file.
Can someone please guide me the right way to set a new delimiter so that vugen recognizes and parses the csv file as I want it to.
I am using loadrunner 12.5
Thanks for your help.
Do you need to upload a file or a line of comma separated variables? Right now you appear to be reading a line of CSV variables, not a file as your parameter file would contain a list of filenames or a single file reference within the directory of the virtual user (extra files, transferred with the use) or created by the virtual user and then uploaded.

CFSCRIPT - How to check the length of a filename before uploading

I ran into this problem when uploading a file with a super long name - my database field was only set to 50 characters. Since then, I have increased my database field length, but I'd like to have a way to check the length of the filename before uploading. Below is my code. The validation returns '85' as the character length. And it returns the same count for every different file I upload (none of which have a file name length of 85).
<cfscript>
missing_info = "<p>There was a slight problem with your submission. The following are required or invalid:</p><ul>";
// Check the length of the file name for our database field
if ( len(Form["ResumeFile1"]) gt 100 )
{
missing_info = missing_info & "<li>'Resume File 1' is invalid. Character length must be less than 100. Current count is " & len(Form["ResumeFile1"]) & ".</li>";
validation_error = true;
ResumeFileInvalidMarker = true;
}
</cfscript>
Anyone see anything wrong with this?
Thanks!

After you upload the file, the variable "clientFileName" will give you the name of the uploaded file, without a file extension.
The only way to read the filename before you upload it would be to use JavaScript to read and parse the value (file path) in the file field.
A quick clarification in the wording of your question. By the time your code executes the file upload has already happened. The file resides in a temporary directory on the ColdFusion server and the form field related to the file upload contains the temporary filename for that file. Aside from checking to see if a file has been specified, do not do anything directly with that file or you'll be circumventing some built in security.
You want to use the cffile tag with the upload action (or equivalent udf) to move the temp file into a folder of your choosing. At that point you get access to a structure containing lots of information. Usually I "upload" into a temporary directory for the application, which should be outside of the webroot for security.
At this point you'll then want to do any validation against the file, such as filename length, file type, file size, etc and delete the file if it fails any checks. If it passes all checks then you move it into it's final destination which may be inside the webroot.
In your case you'll want to check the cffile structure element clientFile which is the original filename including extension (which you'll need to check, since an extension doesn't need to be present and can be any length).
