Using CSV file to read test data from

Question

I need to test a various links of a site (no need to login) with 100's of users and loop it for some number of times using JMeter. I want to put those links in a "CSV file", so that all the links to be tested are read from file.

How do I accomplish this task?

Answer 1

Prepare kind of csv-file with list of your test-params and use it to parametrize your test-samplers, using at least the following:

1. CSV Data Set Config

   Look into the following links for details:

   How to get Jmeter to use CSV data for GET parameters?
   Use jmeter to test multiple Websites
   use csv parameters in jmeter httprequest path
   Force a thread to use same input line when using CSV Data Set Config
   

2. Jmeter functions:

   • __CSVRead,
   • __StringFromFile.

3. Variables From CSV sampler from jmeter-plugins.

1. Prepare your test-urls in csv-file, e.g. in the following format:

    url1
    url2
    ...
    urlN

Ensure that test-URLs don't contain http:// prefix (as per HTTP Request params -> Server).

2. Use schema for your script as below:

    CSV Data Set Config:
    Filename: [path to your csv-file with test-urls]
    Variable Names: testURL
    Recycle on EOF?: True
    Stop thread on EOF?: False
    Sharing mode: Current thread

    Thread Group:
    Number of Threads: N
    Loop Count: M
            HTTP Request // your http call
            Server Name or IP: ${testURL} // use variable with extracted URL

This will start N users, each users will read M entries from list of test-urls. If M > number of entries in list of test-urls then user will recycle the list on EOF.
