You have a programmer who is writing codes for years that comes to you for testing. The programmer might be coding for a number of projects simultaneously or sequentially. Similar would be the case with you. You would be testing a number of projects simultaneously or one after the other. By now your subconscious mind knows the pattern of bug writing while coding by each of the programmer. But since these patterns are not recorded or analyzed you can not predict the probable number of bugs in the next set of a code from a programmer.

You can do that with the help of your bug reports so far you have submitted back to the programmer or development team. Just pull out your last ten bugs reports produced from the code written by the same programmer. Check for a specific number of lines of code how many bugs were found. Based on this one report’s bugs were from how many lines of code. Do the same exercise for all other reports. Take an average for all ten reports.

Based on the number of lines of code, this way you can easily predict the number of bugs that will be there in the fresh set of code submitted by the programmer for testing.

1. A project manager is always right
2. Quality is seriously maintained by developers while developing software
3. A separate set of people (quality control or testers) is not required to take care of the software produced or developed
4. Testers don’t do any substantial value addition in product development
5. Testers lack business knowledge
6. Testers lack technical knowledge
7. Testers lack essential skills to test software
8. Testers don’t understand product requirements well
9. All developments and implementations are prone to extensions because of change in customer requirements or other customer constraints
10. All delays in development and implementation are due to customer
11. Testers have a very little role to play in product development
12. Testers need less than 1% of project time for testing and reporting bugs
13. Testers should be able to test the product well even if substantial knowledge related to product has not been shared with them
14. Testers are the biggest misleading agents
15. Developers and programmers are not testers and thus are not supposed to test what they develop
16. Testers are de-motivators to programmers and developers
17. Testers are project delayers
18. Customers blame development and implementation teams just to hide their own shortcomings
19. Customers don’t know to explain their processes and business rules well
20. Customers are always interested in delaying the project

Why software testing effort estimation is important after functional specifications finalization phase?

If we go by quality standards the sizing of software testing effort has to be done before the tester(s) start writing the test cases for the purpose. The estimate will clearly draw out of the functional specifications signed off between the customer and vendor. Without sizing the Testing manager can never create a testing plan based on which he will decide the number of days and persons required to write test cases, perform testing, draw out the testing results, submit the result report to development team and get the reported bugs resolved. The plan will comprise of time-line and no. of persons required for each of this phase in the sequence mentioned above.

To calculate a reasonable testing time-line estimate based on functional specifications there are certain guidelines that need to be followed: the person who is planning has to have ample business and testing knowledge. Unless (s)he has the right business knowledge (s)he will not be able to select the right persons for writing test cases, or able to guide them on the critical business rules and processes written in the software to hit upon. In that case the best of the test cases will lack the complete coverage and accuracy in testing. The software may lack bug-proofing at the end and customer will be the sole sufferer. Ultimately it is going to effect the software, and the organization that built it.
