Which of the following is a JMeter GUI element used to control the flow of test plans

In JMeter, there are several GUI elements that can be used to control the flow of test plans. Some of the commonly used GUI elements include:

Logic Controllers: Logic Controllers are used to control the flow of requests in the test plan. They allow you to define the order in which requests are executed, as well as add conditions to control when requests are executed.

Simple Controllers: Simple Controllers are used to group Samplers, Configuration Elements, and other Controllers into a logical group. They do not modify the flow of requests.

If Controller: If Controller is a Logic Controller that allows you to control the flow of requests based on a condition. It executes the request only if the condition is true.

While Controller: While Controller is a Logic Controller that allows you to repeatedly execute a request until a condition is met.

Switch Controller: Switch Controller is a Logic Controller that allows you to define multiple conditions and execute requests based on the condition that matches.

Transaction Controller: Transaction Controller is a Sampler that allows you to group requests into a transaction. It measures the overall response time of all requests in the transaction and provides a report.

Module Controller: Module Controller is used to include Samplers, Controllers, and Config Elements from another test plan into the current test plan.

These GUI elements provide flexibility and control over the execution of test plans, allowing users to create complex and comprehensive performance testing scenarios.
