    See Process Method - "The Process method returns a Process object by its application name and index. If the process is not found, the method returns an empty object and posts the message “The process … was not found” to the test log". Majority of the methods in TC are like this i.e. returns object or null.

     

    An empty object doesn't throw an exception.

I would say that majority of methods in TC return either valid object if search succeeds/object exists or empty stub object with the only .Exists property available and set to False if search fails or object does not exist/was destroyed in the application.

Null is almost never returned by 'native' TestComplete methods. Methods like .FindChildByXPath() may return null, but these methods are rather just a wrappers around XPath search engine than 'native' TestComplete methods.
