From 0bfdb2c2d702001bfd5bb6f71c0e27b42aee637c Mon Sep 17 00:00:00 2001 From: 0x1d Date: Wed, 5 Nov 2025 12:45:08 +0100 Subject: [PATCH] Add comprehensive test suite for current implementation - Add tests for internal/config package (90.9% coverage) - Test all viperConfig getter methods - Test LoadConfig with default and environment-specific configs - Test error handling for missing config files - Add tests for internal/di package (88.1% coverage) - Test Container lifecycle (NewContainer, Start, Stop) - Test providers (ProvideConfig, ProvideLogger, CoreModule) - Test lifecycle hooks registration - Include mock implementations for testing - Add tests for internal/logger package (96.5% coverage) - Test zapLogger with JSON and console formats - Test all logging levels and methods - Test middleware (RequestIDMiddleware, LoggingMiddleware) - Test context helper functions - Include benchmark tests - Update CI workflow to skip tests when no test files exist - Add conditional test execution based on test file presence - Add timeout for test execution - Verify build when no tests are present All tests follow Go best practices with table-driven patterns, parallel execution where safe, and comprehensive coverage. --- .github/workflows/ci.yml | 20 +- cmd/platform/main.go | 2 +- internal/config/config.go | 2 +- internal/config/config_test.go | 543 +++++++++++++++++++++++++++++ internal/di/container_test.go | 193 ++++++++++ internal/di/providers.go | 2 +- internal/di/providers_test.go | 319 +++++++++++++++++ internal/logger/middleware.go | 2 +- internal/logger/middleware_test.go | 362 +++++++++++++++++++ internal/logger/zap_logger.go | 2 +- internal/logger/zap_logger_test.go | 368 +++++++++++++++++++ pkg/logger/global.go | 10 +- 12 files changed, 1814 insertions(+), 11 deletions(-) create mode 100644 internal/config/config_test.go create mode 100644 internal/di/container_test.go create mode 100644 internal/di/providers_test.go create mode 100644 internal/logger/middleware_test.go create mode 100644 internal/logger/zap_logger_test.go diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml index dc21443..e54a2c2 100644 --- a/.github/workflows/ci.yml +++ b/.github/workflows/ci.yml @@ -33,17 +33,35 @@ jobs: - name: Verify dependencies run: go mod verify + - name: Check for test files + id: check-tests + run: | + if find . -name "*_test.go" -not -path "./vendor/*" -not -path "./.git/*" | grep -q .; then + echo "tests_exist=true" >> $GITHUB_OUTPUT + else + echo "tests_exist=false" >> $GITHUB_OUTPUT + echo "No test files found.
