BPT有哪些缺点

1. Performance can become poor if too many components are used is a Business Process.

2. There are no Business Process/Test level parameters which makes it tedious to support global Test level variable. We can still use a few workarounds

3. Error handling of BPT is poor. If an error occurs in BPT component then QTP will continue to the next line and I was surprised to see there is no option to change that behaviour

4. On Error option of BPT only allows us to stop the test or continue, it doesn't allow us to end the Test and execute a cleanup component

5. Then there are few UI related things which if would have been implemented in a better way would have helped in increasing efficiency
