Run specific Action in LR – SAP Loadrunner – SAP GUI/WEB by HPE

Hello,

Run preferred Action in Loadrunner

One might encounter a scenario/requirement where a specific Action needs to be Run in a LR script for a specific set of users in a sequence or probably randomly and to be run(action group users) in parallel.

Let’s clearly define how we can implement this :

Problem Statement – When Multiple Actions are implemented for different functionality which might have a dependency on the previous action by just consuming single script.

To keep things simple lets pick for Script 1 that has 3 Actions , “Action1,Action2,Action3” , now load test has to be performed for functionality where virtual users need to run in parallel and one after the other Action.

Which means Action1 has 2 unique vusers , Action2 has 4 unique vusers and Action3 has 8 unique vusers. totaling = 14 vusers .

This is how it should be run — Sequence – Action1 –> Action2  –> Action3

Here we are going to cover two concepts Rendezvous points and Flags

The Solution is illustrated below :

The P_Flags.dat is as shown below :-

As one can see P_Flag1 corresponds to Action1 , P_Flag2 corresponds to Action2 and P_Flag3 corresponds to Action3

Since Action1 has 2 users hence contains 2 true values and similarly for other actions it is shown in multiples of 2

The Action files are implemented below , we use the Flag in this fashion so it runs only that specific Action when TRUE

//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

Action1

{

int Flag1;

Flag1 = atoi(lr_eval_string(“{P_FLAG1}”)); // Value of P_FLAG1 is copied to Flag1

lr_rendezvous(“2_Users”);  // This creates a rendezvous point for 2 vusers which runs in parallel

if (Flag1 == 1)

{

// The steps for the functionality

sapgui_set_ok_code(“/nUCMON”,

BEGIN_OPTIONAL,

“AdditionalInfo=sapgui2015”,

END_OPTIONAL);

sapgui_send_vkey(ENTER,

BEGIN_OPTIONAL,

“AdditionalInfo=sapgui2015”,

END_OPTIONAL);

} //End IF

} // End of Action1

Similarly for the remaining actions lets put the code

//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

Action2

{

int Flag2;

Flag2 = atoi(lr_eval_string(“{P_FLAG2}”));

lr_rendezvous(“4_Users”); // This creates a rendezvous point for 4 vusers which runs in parallel

if (Flag2 == 1)

{

// The steps for the functionality

sapgui_set_ok_code(“/nUCMON2”,

BEGIN_OPTIONAL,

“AdditionalInfo=sapgui2015”,

END_OPTIONAL);

sapgui_send_vkey(ENTER,

BEGIN_OPTIONAL,

“AdditionalInfo=sapgui2015”,

END_OPTIONAL);

} //End IF

} // End of Action2

//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

Action3

{

int Flag3;

Flag3 = atoi(lr_eval_string(“{P_FLAG3}”));

 

lr_rendezvous(“8_User”); // This creates a rendezvous point for 8 vusers which runs in parallel

 

if (Flag3 == 1)

{

// The steps for the functionality

sapgui_set_ok_code(“/nUCMON3”,

BEGIN_OPTIONAL,

“AdditionalInfo=sapgui2015”,

END_OPTIONAL);

sapgui_send_vkey(ENTER,

BEGIN_OPTIONAL,

“AdditionalInfo=sapgui2015”,

END_OPTIONAL);

} //End IF

} // End of Action3

Upon following these above steps one can achieve it very easily

Additionally, as a best practice one can also print/output the Group name if needed for better reporting

char TransName[70];

strcat(TransName,lr_eval_string(“{P_CONS_GRP}”)); // copy the group name to the string

then for the specific activity one can start and end the lr transactions like this

lr_start_transaction((char *)TransName);

lr_end_transaction((char *)TransName,LR_AUTO);

Contents of P_CONS_GRP

For how to create Rendezvous points in LR , please refer to the document shown in the Comments section, I hope you find this useful!
