From 9f9321be41334336b5224475402a83ee61830850 Mon Sep 17 00:00:00 2001 From: Rohit Patil Date: Tue, 10 Feb 2026 17:52:17 +0530 Subject: [PATCH 1/5] Migrate e2e test suites to Ginkgo v2 framework This commit migrates the e2e test suites for encryption, encryption-rotation, encryption-perf, and OIDC tests from Ginkgo v1 to v2 framework. The migration includes: - Update test suite initialization to use Ginkgo v2 syntax - Replace deprecated test main functions with proper suite setup - Extract test logic into separate package files for better organization - Fix type assertions and error handling in e2e tests - Add HTTP client safety measures and nil pointer checks - Fix gofmt formatting issues - Update test suite definitions to match CI job configuration - Add encryption wrapper utilities for common test operations Co-Authored-By: Rohit Patil --- .../main.go | 67 + test/e2e-encryption-perf/encryption_perf.go | 114 ++
