Hey all,
I am using Apache JMeter 2.7 to load test Liferay. One such test I am creating
involves dynamically generating files and uploading them to Liferay's Document
and Media portlet. The problem I'm having has nothing to do with Liferay
though...I know this because I can upload a document if I type the exact path
into the "file path" box of "Send Files With the Request" in an HTTP request.
This is not how I need the test to run.
I want the test to run in such a way that I generate a unique file each loop of
the test with a different UUID for the file name(I do so in a BeanShell
PreProcessor and it does as I want). I have a user defined variable FILENAME
that I use to store the file name. In the HTTP Request, for the file path I use
the path "C:\Installs\Apache Jmeter\apache-jmeter-2.7\bin\${FILENAME}" but
JMeter does not process the variable. When I view the Results Tree, I see the
error:
java.io.FileNotFoundException: C:\Installs\Apache
Jmeter\apache-jmeter-2.7\bin\${FILENAME} (The system cannot find the file
specified)
Yet, if I hard code the file path(for example ...\bin\doc.txt) and use
${FILENAME} as the value for the title of the document(a parameter I send in
the HTTP Request), the document(doc.txt) uploads to the portlet with the string
value of FILENAME as the title. This lets me know the right string is stored in
the variable FILENAME. From this, I deduce that JMeter simply does not replace
variables in the file path for sending files in an HTTP Request. If I am
incorrect in this conclusion, please let me know how to fix whatever error I
have. Has anyone else had this problem?
I am currently trying to create a work around by adding a BeanShell
PreProcessor to this http request that would dynamically update the filepath
with the variable name. I would need to set some variable =
vars.get("FILENAME"). Anyone know how to proceed from here to set the HTTP file
path programmatically? I'm looking in the API
http://jmeter.apache.org/api/org/apache/jmeter/protocol/http/sampler/HTTPSamplerBase.html
for the answer. Any help would be much appreciated because I am completely
stumped right now.
I've tried making this PreProcessor myself, but it does not work:
HTTPFileArg file = new HTTPFileArg("C:\Installs\Apache
Jmeter\apache-jmeter-2.7\bin\doc.txt", "_20_file", "text/plain");
sampler.setHTTPFiles(file);
I've seen similar questions but none of the answer helped me and I haven't ever
seen someone do what I want to do programmatically.
Thanks,
Will Henry
