Window didn't respond, after waiting for X ms System.OutOfMemoryException thrown

[Priyank06]

Hi Friends,

I have implemented white test case for one of the functionality of application.
Functionality which test case is executing is something like from home screen of application it will navigate to other screen after clicking button on home screen, then on landing screen it will repeatedly click on button for 50 times which is performing operation of saving data and reading data.

Requirement of the test case was to check reliability of application and in doing that test case was suppose to run for number of minutes user has enter. Code for test case was something like.

`[TestMethod]
public void TestcaseName()
{
// Take memory snapshot
Stopwatch sw = new Stopwatch(); // Stopwatch to compare time if it is equals or exceeds time enter by user.
sw.Start();
bool needToRepeate = true;
While(needToRepeate)
{
// do white framework code which will execute functionality
}

if(sw.Elapsed >= time enter by user in minutes)
{
needToRepeate = false;
// Take memory snapshot
sw.stop();
}
}
`

Error had occurred when running test case continuously for 7 days it will be breaking at 3rd day following is logged error.

Value for CoreAppXmlConfiguration.Instance.BusyTimeout = execution time enter by user in minutes * 60000 + 5000;

I tried to figure out why OutofMemory exception white framework is having, but i didn't found this error in application log file where i am catching every exception.

Can anyone help me out on this please

Thanks in advance
