# Thread: When are you going to be finished...

1. ## When are you going to be finished...

Hello Friends,

Like myself I'm sure that most of us testers come across this question.."So how long is it going to take you to complete your testing?"

Does anyone have any templates that can be used to track testing progress?
Thanks!

For manual testing, I take the number of test cases and multiply it by 1/2 hour.
For example, I have 400 test cases left to execute, so it will take me 200 hours.

Then I take the number of errors detected so far, divide it by the number of tests executed, and determine the rough error rate. For example, 23 errors detected, 167 tests executed. This is an error rate of 13.7%.

Since I have 400 tests left to execute, I multiply it by the current error rate. Using this formula, I anticipate I will encounter another 55 errors. I add existing and anticipated errors - this gives me 78 retests, if full regression testing is not necessary. 78 tests X 1/2 hour is about 40 hours.

I then add the time required to execute new test cases (200 hours) and the time I'll need for retests (40 hours) for a total of 240 hours.

I can pretty much guarantee the result will make development choke. However, the results are usually pretty close, if you exercise all of your tests and retests.
The fact that you apply some formulae to your estimate will at least guarantee that if they don't really want, or can't accept, the answer, they won't come and pressure you in that way any time soon.

By the way (just to avoid replies saying "1/2 hour!"). That is the average. Some tests take 2 minutes; some end up taking half a day - or more. The timeframe is based on 6 year study conducted by a large QC organization who was tired of being asked that very question and being wrong every time. They set out to come up with numbers that worked; these did. Nor is this the methodology in its entirety; it's just the quickest way I know to give a decent ballpark estimate when asked that particular question.

I hope it helps - it's helped me many times...

Johnny,

Go over to QADownloads and look at the Template section. There you will find a set of Excel templates (Test Status Templates in Excel) I placed out there a while back. See if these will help.

This is a classic effort estimation problem. I'd recommend doing a search on estimation - also you'd want to look up the Estimation and Planning forum.
