From a9844a145178752bce472f915101b72d96115721 Mon Sep 17 00:00:00 2001 From: anonpenguin23 Date: Wed, 31 Dec 2025 12:26:31 +0200 Subject: [PATCH] feat: add unit tests for gateway authentication and RQLite utilities - Introduced comprehensive unit tests for the authentication service in the gateway, covering JWT generation, Base58 decoding, and signature verification for Ethereum and Solana. - Added tests for RQLite cluster discovery functions, including host replacement logic and public IP validation. - Implemented tests for RQLite utility functions, focusing on exponential backoff and data directory path resolution. - Enhanced serverless engine tests to validate timeout handling and memory limits for WASM functions. --- pkg/gateway/auth/service_test.go | 166 ++++++++++++++++++++
