Hello Guys,

I couldn’t find anything about this in the documentation, I am wondering if we can **loop within the exec** function in Gatling, as in **looping over a check**.

**What I want to achieve :**

`  
def postOrder(shipmentListTwoProducts: ShipmentList) = {

exec({  
http(“POST Order”)  
.post(applicationConf.getString(“pathPostOrder”))  
// I want to loop here over shipmentListTwoProducts.shipmentList that s=is an array, so I want to call the check as many times as there are items in the array each time // passing a different variable to shipmentListMappingChecks method  
.check(  
ShipmentListChecks.shipmentListMappingChecks(  
index): \_\*)  
})  
}

`
