Lo que suele suponerse

gin.Context implements context.Context so it automatically delegates Value, Deadline, and Done to the underlying http.Request context without extra configuration.

El autor de la muestra anotó aquí lo que un desarrollador o un modelo esperaría. El contrato de abajo es lo que realmente se ejecutó.

Contrato

• By default gin.Engine has ContextWithFallback disabled, causing gin.Context to return nil for all http.Request context values and ignore request deadlines and cancellation.
• assert setting ContextWithFallback to true enables gin.Context.Value to resolve values from http.Request.Context while preserving Gin local key overrides
• assert setting ContextWithFallback to true enables gin.Context to propagate cancellation and deadlines from http.Request.Context via Done, Deadline, and Err
• assert Context.Get and Context.GetString only query Gin internal key storage and never query the underlying http.Request.Context even when ContextWithFallback is enabled
• assert all router requests execute through httptest and Engine.ServeHTTP in memory without binding network listeners
