Problem reading value of a test parameter from a data file.
Hi,
I am trying to create a data driven test in JMETER using the instructions on
http://wiki.apache.org/jakarta-jmeter/JMeterFAQ#head-87f846dad28fd6b2ad5eb0d
44d527d572f810653 under the question "How do I use external data files to in
my Test scripts?".
1- I am not clear with the format for specifying value of the
parameter when using the "User Parameters" preprocessor. I have given value
the parameter "fName" as "${_StringFromFile(user.dat)}". Is the format for
specifying value of the parameter correct? However, JMETER doesn't attempt
to read from the data file user.dat. As a result, data posted for my
subsequent request is evaluated as firstName=${fName}. The ${fName} is not
getting substituted by the value in the data file. Is _StringFromFile a
JMETER function that is invoked to read the data from the mentioned file?
2- I have specified the data in "user.dat" with the first line reading
as FNAME & subsequent lines have values in it. Is the data file format
correct?
What could be the problem?
Thanks in advance,
Rajendra

_StringFromFile each time it's called it reads next line from the file,
So have a file with firstName,lastName in one line with some separator
then use the __split function to get firstName and lastName
e.g if the content of user.dat are
lName1|fName1
lName2|fName2
lName3|fName3
then you can have
name=${_StringFromFile(user.dat,name)}
VAR=${__split($name,VAR,|)}
${VAR_1} will give you lastName
And ${VAR_2} will give firatName
OR
Use CSV Data set Config
Thanks

I think it is better to use the CSV Data Set Config element. There you
specify the filename, variable names, etc. Then you just use the variables
in your test plan and the CSV Data Set Config takes care of reading the next
line for you.
