Based on the project, which is specified in test plan and min. is 25% out of total dev. time.

It is 3:1
i.e., If the developing is one day means the testing will takes 3 days.

So, when using a % of development hours to estimate testing hours (40% for example), what type of testing is included in that figure?  Functional only?  What about for UAT?  Further, how should the 40% be broken down?  What % for preparation of tests (cases, etc), what % for execution and what % for defect tracking?  Any good guidelines?

There is no such standard mentioned anywhere in the industry as such this much amount of time must be spent on the Testing task. It wholly depends upon the application and its criticalities. There are cases that require more time for testing compared to development time.

As per the standerd we are following, the testing process is starting at the same time development starts. When they start developing testers are starting to prepare Test Scenarios and Test cases. Once these documents get approved we are starting testing the project as a whole or the modules which is completed development. So that developers can fix the bugs also by the time of developing. Once the whole project is completed we do integration testing, system testing, installation testing,UAT.

The testing estimation was very simple as per Industry standard practice. The inputs for this process , provided by the development team, where : the size of the Dev team and the number of working days needed for building a solution before starting systems tests.

The testing estimation process said that the number of testing engineers would be HALF of the number of Dev Team and one third of the total number of Development days / hours.

Take a look at the below formula:

Testing Working days = (Development working days) /3
Test engineers required = (Development engineers) / 2

Testing Cost = Testing Working days * Test engineers * Test Engineer daily cost.

I hope this helps..

General industry standard is 40% of total Project time. It may vary depending on the project and also the type of testing to be performed

There is no standard defined to estimate the testing efforts as it's governed by number of factors. Team's velocity is the used to measure on an average how many user stories a team can deliver in a sprint. Same principle can be used to decide how many user stories can be tested in a sprint. Based on experience in few sprint's velocity for testing can be derived.

It depends upon following Factors:
1. Type of Project/Delieverable.
2. Scope of Testing.
3. Types of Testing to be Performed.

Testing can vary for 30%-50% of total Development Time. I have considered the case of Manual Tesing here. Automation can reduce the end delieverable timelines.
