To know how we are performing testing on the current build, we can match the current number of found defects with the predicted data and then take decisions of - Are we in the right direction? Are we missing anything, why there is a difference? etc

Is there any estimation techniques available to do this? Any experiences on this please share.

Thanks. We'll let you know when a new response is added.

You can make a guess based on how good your programmers are. Better programmers will make less errors than junior programmers.

    But, how do you measure "how good" the programmers are ? This kind of estimation can only be made analyzing data from previous projects, and that is one of the reasons to document the testing results. Have you heard of Personal Software Process (PSP) and Team Software Process (TSP) ? These software development processes pay special attention to the collection of statistics about development times, defects and other metrics so they can be used to make better estimations in future projects.
