How to use __StringFromFile function with Beanshell Preprocessor
For example, i have a text file which contains comma separated values as in the attachment.
I want to read data from these file and assign to variables.
If you want to read complete file and store it into one variable than paste
${__FileToString(C:/path,,Variable_Name)}
command in beanshell preprocessor and pass ${Variable_Name} where you want to use it
But
If you want to read line by line than you can choose __StringFromFile function, you can also use csv data set config to fulfill you requirement, just change delimiter , to some other delimiter like ~ (As you mentioned your values are separated by comma). It will capture complete line and store into one variable

I am using ubuntu and i have used a library named as ICLI (interactive command line interface) which lets one build his own prompt. and i want whatever command i write in this prompt to be stored as JSON.
One way of doing so is file write, for which you can try
with open("data_file.json", "w") as write_file:
json.dump(data, write_file)
Here, data is a variable created before writing these lines. data contains whatever information needs to be stored, in JSON format.
I have a CSV file from which I am reading parameters.
I want using Flexible File Writer to write the extracted values I am able to write Available Fields but I want to write the variables I am reading from CSV as well as extracted response but extracted values are not being written also the headers and values are written in the single cell I want those to be written in separate cells.
Is there any possibility to read files from .csv into array of variables?
Instead of getting:
https://loadtest.com/mo/75245.json
https://loadtest.com/mo/190554MHG.json
https://loadtest.com/mo/190223MJG.json
https://loadtest.com/mo/198533FTR.json
...
I would like to get an array:
https://loadtest.com/mo/75245.190554MHG.190223MJG.198533FTR.19023.HGTYTRWEYRWEHF.1922MHGDGO.json
Does anybody have some idea?
Thank you in advance.
Check out the following JMeter Functions:
__FileToString() - to read your CSV file into a JMeter Variable
__split() - to "split" the aforementioned JMeter Variable holding CSV file content into separate variables using any suitable delimited (comma, tabulation symbol, newline, whatever)
A workaround for this, if you don't want to use Groovy, can be using text editor that supports regex (like Notepad++) to restructure your CSV, so that multiple lines are collapsed into a single multi value line.
An example for Notepad++ would be replacing all instances of:
^(.+)\R(.+)\R(.+)\R
With
$1 $2 $3
To collapse every 3 lines of text into a single line.
Then you can just use that one line as a single variable in JMeter. This way I've passed multiple comma separated Ids into an array in an Http request. Remember to use a different delimiter in JMeter CSV Data Set Config for actual CSV columns, than the one used to delimit your multiple values.
I have the following config file:
[GENERAL_CONFIG]
filter_subnetworks = 192.168.105.0/24 1.1.0.0/16 192.168.105.0/24
192.168.105.0/24 1.1.0.0/16 192.168.105.0/24
192.168.105.0/24 1.1.0.0/16 192.168.105.0/24
and i want to read all subnetworks with g_key_file_get_string_list (gkf, "GENERAL_CONFIG", "filter_subnetworks", &s_len, &error) but this function read one single line.
It looks like your input file doesn't comply with the formatting required by the glib Key-value file parser functions.
All key values should be on a single line, and you should have an explicit list separator character (not just space) such as ; or ,, see the g_key_file_set_list_separator() function.
Convert the file to comply with the required glib format if you're going to use their API. Note that as soon as you save your file back out, it will use the glib API, so there's little point in "tricking" it to load something else.
I am trying to take an input from a text file in this format:
Processed_kplr010074716-2009131105131_llc.fits.txt
Processed_kplr010074716-2009166043257_llc.fits.txt
Processed_kplr010074716-2009259160929_llc.fits.txt
etc.... (there are several hundred lines)
and use that input to name my output files for a Matlab loop. Each time the loop ends, i would like it to process the results and save them to a file such as:
Matlab_Processed_kplr010074716-2009131105131_llc.fits.txt
This would make identifying the object which has been processed easier as I can then just look for the ID number and not of to sort through a list of random saved filenames. I also need it to save plots that are generated in each loop in a similar fashion.
This is what I have so far:
fileNames = fopen('file_list_1.txt', 'rt');
inText = textscan(fileNames, '%s');
outText = [inText]';
fclose(fileNames)
for j:numel(Data)
%Do Stuff
save(strcat('Matlab_',outText(j),'.txt'))
print(Plot, '-djpeg', strcat(outText(j),'.txt'))
end
Any help is appreciated, thanks.
If you want to use the save command to save to a text file, you need to use -ascii tab, see the documentation for more details. You might also want to use dlmwrite instead(or even fprintf, but I don't believe you can write the whole matrix at once with fprintf, you have to loop over the rows).
