# Thread: How calculating testing time for the project

1. ## How calculating testing time for the project

How u r calculating testing time schedule for any project

2. ## Re: How calculating testing time for the project

We use our past experience and expertise, along with all knowledge of the new project, to guide us.

3. ## Re: How calculating testing time for the project

But is there any formula through which we can calculate such as I have 15 requirements say 15*2=30 days r required something like that

4. ## Re: How calculating testing time for the project

No. There is no forumla that works across companies (nor across projects, in my opinion). Some have tried, but I don't know any that really work in general. Too many cases where "it depends".

For example, see this:

You could certainly invent a forumla for your company, though - some folks do that. If you do, be sure to re-calibrate it periodically.

One question to ask yourself is "How accurate do the estimates need to be?" If they don't need to be accurate at all, then you can invent a formula such as (Requirements * 2), or (Development Estimate / 3).

If, on the other hand, you are being held accountable for the accuracy of the estimates, then I think you can do far better than some formula, by using your knowledge and experience, and considering each project individually.

I'm trying to get a estimative from a test project,
well, actually ours estimatives start from ours Test Case, that is created based on the Business need (objective of client on testing) , and we set the "how much" the test will last, according with the experience and previous informations we received, it means, a "Feeling".

But, since sometime ago, I've noticed I need to start to estimate from a more solid method, a formal one, so I wanna try to begin with FP (Function Point), or even TPA - Test Point Analysis, to estimate the Test Project.

There is some one that already try? already had a experience with this Estimative of Test Case?

thanks for all...

I find tea leaves, knuckle bones and crystall balls have as much precision as some of the methodologies I have seen used in my 15 years. I reckon any testing schedule can be based on the length of a string, especially if it is linked at the ends into a noose which the PM can use to hang the test lead.
There is also some strange things like multiply 2.5 or for every new resource reduce by .01 eg if we have 1 user divide number of test cases by 1. if two users. divide the number of test cases by / (1 +.9) . If three users number of test cases by / (1 + .9 + .8). Dont ask me why this is done, just some mythical management going on, if you ask me.
