Encountering Problem with Jmeter Script Playback - Kindly Activate JavaScript to Access Page Information

I'm currently experiencing a challenge when trying to simulate the following scenario in my JMeter script. I would truly appreciate any assistance or solutions you can offer.

My goal is to create a JMeter script for a form submission process within a .NET application. One of the HTTP Request Samplers is being redirected to another HTTP request. While my JMeter script replay successfully redirects to the correct HTTP request, it fails to provide the necessary HTTP response.

The error message reads: "Please enable JavaScript to view the page content. Your support ID is: 7865380748200702010."

During script recording, I receive the appropriate response with .NET variables such as View State, View State Generator, Event Validation, and more.

If anyone has encountered this issue before, please lend me your expertise.

Answer №1

There may be an issue with the requests you are sending, possibly due to missing or improperly implemented correlation of dynamic parameters in your script.

In most cases, replaying a recorded test scenario is not possible because of incorrect hard-coded values for elements like View State, View State Generator, and Event Validation.

While browsers automatically send these variables, JMeter requires manual extraction from previous responses using a suitable PostProcessor (such as CSS Selector Extractor), conversion into JMeter Variables, and replacing hard-coded values with variables. For correlation examples with .NET web applications, refer to the article on ASP.NET Login Testing with JMeter.

Regarding JavaScript, Apache JMeter's main page states that JMeter does not execute JavaScript found in HTML pages and does not render pages as browsers do. If a page element loads via JavaScript (using AJAX), JMeter requires proper simulation as it won't execute this request automatically.
