Parallel file upload using jMeter
<p>I am trying to create a jMeter script to perform file upload operation to a web application:</p>

<p>Test Plan
    Thread Group
        Launch application
        Login
        Navigate
        Upload
        Logout</p>

<p>In above case when we have multiple thread group then multiple files are getting uploaded. Although my requirement is to perform multiple upload operation (in parallel) in one thread operation.</p>

<p>How can this be done?</p>
