The next release of Test Design Studio 2.0 will include a new feature to perform file locking in Quality Center / ALM.  When you open a test, attachment, resource, or BPT component for editing, Test Design Studio will attempt to acquire a lock on that file.  If the file is already locked by another user (either through Test Design Studio or tools like QuickTest), you will be notified that the file is locked.  At that time, the file will open in read-only mode.

This new feature should help teams collaborate without impacting the work of someone else.  If you prefer to disable the locking feature, you may do so using Test Design Studio options.  Select ‘Tools –> Options’ from the main menu, then expand the path for ‘HP –> Quality Center’.  Here you will find the option to enable/disable file locking.

We hope you enjoy this new feature coming in build 2.0.4571.

[Update] The new release of Test Design Studio 2.0.4572 is now available and includes this new feature.
