Capturing milliseconds' difference between events

Hi,

We are involved in performance testing of a .net application, wherein we need to find the time gap between the start and end of an event. We are using aqDateTime.Now at the start and end of the events and measuring the difference. However, there are some events which happen within the time span of a second, and we are unable to capture the time gap between the start and end. Is there a technique / provision in TestComplete to capture the time gap between events in millisecocnds? I request the pros to kindly enlighten me on this...

Well, I lied, I didn't search properly first :)

The solution for VBScript looks like this

Dim tFrom, tTo, tDif

tFrom = Timer

aqUtils.Delay 100

tTo = Timer

tDif = Int((tTo-tFrom) * 1000)

Log.Message tDif

Hi Raghu,

You need a special profiling tool for the real application performance testing. AQtime by SmartBear (http://smartbear.com/products/qa-tools/application-performance-profiling) is one of such tools.

If you are thinking about performance measurments from the end-user point of view, then your and Gennadiy's approaches are fine, but in this case you should not need milliseconds precision.

Hi Raghu,

Have you checked out HISUtils.StopWatch ? It mesures to the millisecond.

Ref here.

In JScript you can use the following example:

var dateFrom = new Date();

aqUtils.Delay(100);

var dateTo = new Date();

var dif = dateTo.getTime() - dateFrom.getTime();

Log.Message(dif);

However, I haven't found anything similar in VBScript

Hi Simon, Alexei, Gena,

Many thanks for your responses. Simon, we've found that HISUtils.StopWatch and its methods are best suited for our purposes. Thanks again for that.
