Difference between Behaviour-driven development (BDD) and Behaviour-Driven Testing (BDT)

I am looking into different software testing techniques and I have come across Behaviour-Driven Testing (BDT) and from what I understood is that it’s just the testing aspect of BDD and can be used without the BDD.

But when I started looking into Behaviour-driven development (BDD), I’ve noticed that everyone seems to angle it as a software testing technique rather than a software development process.

So I have two following questions:

1 - Is there such thing as Behaviour-Driven Testing (BDT) in practice?

1.1 - If YES - Is there any difference between BDD and BDT?

1.2 - If NO - would you classify BDD as a software testing technique?

Here is some of the information I have been reading on BDT:
