Tracking Memory Usage

I m not sure this can be done with TC. To keep track of memory usage in your application you need a separate tool called AQtime

Hi Chris,



You can get the private working set using WMI classes, namely, Win32_PerfRawData_PerfProc_Process.WorkingSetPrivate.

 function TestGetPrivateWorkingSet()

 {

 Log.Message("Notepad's private working set: " + GetPrivateWorkingSet("NOTEPAD") + " bytes");

 }

 

 // Returns the private working set, in bytes, of the specified process.

 // Parameter:

 // ProcessName - the process name without the extension (case-insensitive). E.g. "notepad".

 function GetPrivateWorkingSet(ProcessName)

 {

   var oWMI = GetObject("winmgmts:");

   var oPerfData = oWMI.Get("Win32_PerfRawData_PerfProc_Process.Name='" + ProcessName + "'");

   return oPerfData.WorkingSetPrivate;

 }

If you need to query memory several times throughout your test, you can use the following code with a WMI refresher. This should work faster than calling GetObject("winmgmts:") multiple times:

 function Test()

 {

   InitCounters("notepad");

 

   // Do something

 

   Log.Message(GetPrivateWorkingSet());

 

   // Do something else

 

   Log.Message(GetPrivateWorkingSet());

 }

 

 var oCounter;

 

 function InitCounters(ProcessName)

 {

   var oRefresher = new ActiveXObject("WbemScripting.SWbemRefresher");

   var oWMI = GetObject("winmgmts:");

   oCounter = oRefresher.Add(oWMI, "Win32_PerfRawData_PerfProc_Process.Name='" + ProcessName + "'");

 }

 

 function GetPrivateWorkingSet()

 {

   oCounter.Refresher.Refresh();

   return oCounter.Object.WorkingSetPrivate;

 }

Take a look at: Adding Performance Counters

Thanks for the reply, but showing the memory for every action the test does in the test log, while useful, is not quite what I was looking for.



I am looking to grab the memory for a few particular steps during a test run, and be able to record that in an excel file for example, and then write a script to manipulate that data into a report for managers to look at.



The managers would not be too keen on looking through the memory for every single action the test does and I did not notice any way to manipulate the performance counter in a script.



If there is a way to do that, then this is a possibility, but I am certainly not going to go through the results manually and pull out the few pieces the managers want to see.



Optimally, I was hoping for another property like memusage that just showed the private memory usage, which I could record to excel during the test run only when I want to.

Thanks for the reply, but understandably, I was hoping to not have to spend money on another tool.  I am wondering if I cannot suggest a feature enhancement for TestComplete to have a private memory property on the process.  Though, if they already have another tool for memory profiling, I guess it probably wouldn't happen.

Helen,



Thank you.



I gave your suggestion a try and it looks like I will be able to do exactly what I had hoped to.
