The Design Page

The Design page lets you list and create 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

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

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,
