How do you break a while loop in JMeter?
The condition can be any variable or function that eventually evaluates to the string ‘false’. So, you need to specify a variable or function in While Loop, that has value ‘true’ and becomes ‘false’ somewhere else in the script. Once it changes to ‘false’, JMeter will exit the While loop.
What is loop count?
A common type of program loop is one that is controlled by an integer that counts up from a initial value to an upper limit. Such a loop is called a counting loop. The integer is called a loop control variable. Loops are implemented with the conditional branch, jump, and conditional set instructions.
What is if controller in JMeter?
The main purpose of the If Controller is to control the JMeter execution script flow. This basically means that you can run samplers only if a certain condition is true.
When to use the JMeter while controller while loop?
IF the condition is true, THEN execute the statements inside the IF block. JMeter implements this while loop by using the JMeter While Controller. The JMeter While Controller basically runs children Samplers and the controller continues to run until the condition becomes false in the condition field. The possible condition values could be:
How is a while condition evaluated in JMeter?
JMeter has many built-in functions that can be used to evaluate a while condition. Many of these functions can be reused in While conditions. Most JMeter variables are stored in String format, so make sure to use the javaScript function or similar to compare the variable value to the string value.
When to use a while loop in JMX?
Also you can use the $ {__jexl3 (,)} function to evaluate the result. While with Counter: A while loop can be seen as a for loop when used in conjunction with a counter. You can download a sample JMX file from here.
What’s the difference between a property and a function in JMeter?
JMeter Property – the same as Function or Variable, but assumes the Property instead. Both the Function/Variable and Property approaches assume that the “Condition” will be set to “false” somewhere in or outside the loop. In the case of Property, it can be done from another Thread Group or even outside JMeter, for example via the Beanshell Server.
