Scenarios

In the previous lesson, we learned about the features offered by Gatling. In this lesson, we will learn about scenarios.

What is Scenario?

Scenario represents the actions performed by a user.

The exec method in a scenario is used to execute an action, which can be any of the following request types:

• http – execute a HTTP call.
• ws – execute a Web Socket call.
• jms – make a Java Messaging Service request.
• sse – make a Server Side Event request.
• mqtt – make a Message Queuing Telemetry Transport request. This option is applicable only to the commercial version of Gatling, Frontline.
• inject or manipulate data in the user session.

Each of the building blocks has its own construct for making the request.

A simulation file can have multiple scenarios, and each scenario needs to have a unique name.

Sample simulation

In the below sample simulation, we have a scenario that executes an HTTP call and a Web Socket call in a sequence. We can have a mix of all the possible building blocks.
