How do you identify a wormhole?

Could you please elaborate on the process of identifying a wormhole? I'm particularly interested in understanding the key characteristics or signatures that would indicate the presence of such a phenomenon. What are the scientific methods or techniques typically employed in this endeavor? Is there a specific type of equipment or instrumentation required? Additionally, how does the identification process differ when dealing with wormholes in theoretical physics versus those potentially detectable in the real universe? Thank you for clarifying these points.
