The Design Page

The Design page lets you list and create Virtual Users. It is the landing page of each project, but also accessible through a click on the upper design menu or on Virtual Users in the same menu:


Virtual users

A Virtual User (shortened VU) represents a user journey through your application. It lets you simulate a real user behavior.


For each VU, the list displays:

  • The name and description,
  • The creation and edition dates,
  • The number of containers,
  • The number of actions,
  • The type of VU (JMeter or WebDriver).

Virtual Users list actions

Edit VU

Several actions are available when placing your mouse over an existing connection in the list:

Icon Action Description
Duplicate VU Lets you duplicate a VU in one click. You can then edit the duplicated VU.
Delete VU Lets you remove a VU in one click. This operation cannot be reverted so proceed with caution.

Design Tables

From the table view, you can filter the displayed VUs using the table column header Filter fields:

  • Name
  • Description
  • Tags


By default the table is filtered by the current Project tags.


You can also click on the column headers to sort the VUs. By default, they are sorted by ascending last modification date.

Create a VU

Create VU

To create a new virtual user simply click on the big blue Plus button to display the creation form.

Then there are several methods to create a virtual user:


Record Http Archive



  • Fragments VU are a special kind of virtual user that cannot be executed. Their actions are meant to be shared using Link Actions.


We strongly recommend to record your web application using Fiddler or FireFox as they also record response contents.

HAR Format

HAR is an abbreviation for Http Archive:

The HTTP Archive format or HAR, is a JSON-formatted archival format for logging of a web browsers interaction with a site. The common extension for these files is .har.

Several browser like Chrome or Firefox supports recording HTTP traffic as HAR natively. Most 3rd party capture proxies like Fiddler or Charles proxy also allow you to generate HAR files.

Remove a VU

Remove VU

The following procedure explains how to remove a virtual user and all of its content:

  1. Go on the design page,
  2. Place your mouse over the VU you want to remove,
  3. Click on the Delete button that appears next to the VU name,
  4. Click on Yes to confirm the deletion.


Deleting a VU deletes all the data it contains. Proceed with caution.
