Use the While operation to run child operations in a loop until the specified condition is kept. For example, your browser can send some request to the tested server and the server responds with the "in progress" message until the request is processed. You can use the While operation to wait until the “in process” responses end. To exit the loop earlier, use the Break operation.
|Number of occurrences:||Unlimited.|
|Parent operations:||Any other operation. If the scenario editor displays pages and connections, the operations cannot be placed between a page and a connection.|
|Child operations:||This operation can have any other operation as a child. The number of child operations is not limited.
The child operations will be executed on each iteration in the order of their appearance in the Scenario Explorer tree.
The Think Time edit box at the top of the editor specifies the number of milliseconds the operation will wait before it starts executing.
The SLA edit box at the top of the editor specifies the maximum acceptable duration of the operation, in milliseconds.
On this page, you specify conditions to be checked on each iteration.
|Note:||The operation checks conditions at the beginning of each iteration. If the conditions evaluate to False at the very beginning, no iterations are made.|
