I have some queries in QC

1. How can we protect the scripts in QC?
2. How can we change the shared object repository path (after saving the QTP scripts in QC)?
3. Give more information on BPT.

1. As for protecting the scripts in QC, its always better to have different access control for different projects in QC. This will restrict the use of the scripts to a particular project only. And people working in one project will not go and mis-handle the scripts.

2. You either have to remap the new path for the OR to each and every script or there is another alternative. You can make a .vbs file and put the path of the OR into it and map it to the QTP scripts. And then run the OR dynamically from the Script. This will be an one time effort because you can change the path of the shared OR any no. of times and you will just have to modify the ".vbs" file and save. But in case you change the path of the shared OR repeatedly you will have to always change the mapping of the OR into each and evry script.

3. BPT is a framework or a best practice practiced very commonly. BPT shands for Business Process Management. This framework runs on the concept of Business Components instead of scripts. The reuseable parts are broken into reusable components and these are mapped to one Test to make a scenario in the Test Plan. These "Tests" are mapped to the execution grid of the Test Lab creating a New Test Set. Now the Test Set is run and it generates the report. This is the basic of the BPT framework.
