What is Gson

Definition

Gson is an open-source Java library from Google used to convert Java objects into JSON and JSON strings back into Java objects, a process known as serialization and deserialization.

Why Testers Use Gson

• Building request payloads from Java objects instead of hand-writing JSON strings.
• Parsing API responses into strongly-typed Java objects for easier assertions.
• Comparing complex JSON structures programmatically rather than as raw text.
