From 4d00af75b6dc355d19af2d807bcd75381c301db5 Mon Sep 17 00:00:00 2001 From: GitHub Actions Date: Mon, 16 Feb 2026 21:20:34 +0000 Subject: [PATCH] fix(tests): enhance database setup for unit tests and address CI failures - Implemented a function to create a valid SQLite database for testing in db_health_handler_test.go. - Replaced dummy database file creation with a proper SQLite setup to ensure tests run against a valid database. - Set CHARON_ENCRYPTION_KEY environment variable in dns_provider_service_test.go to prevent RotationService initialization warnings. - Added detailed remediation plan for CI Codecov backend test failures, addressing encryption key requirements and database record not found errors. --- .../api/handlers/coverage_quick_test.go | 24 +- .../api/handlers/db_health_handler_test.go | 22 +- .../services/dns_provider_service_test.go | 7 + .../ci_codecov_backend_failure_remediation.md | 1184 +++++++++++++++++ 4 files changed, 1232 insertions(+), 5 deletions(-) create mode 100644 docs/plans/ci_codecov_backend_failure_remediation.md diff --git a/backend/internal/api/handlers/coverage_quick_test.go b/backend/internal/api/handlers/coverage_quick_test.go index 901a7253..9bdd6661 100644 --- a/backend/internal/api/handlers/coverage_quick_test.go +++ b/backend/internal/api/handlers/coverage_quick_test.go @@ -4,22 +4,40 @@ import ( "encoding/json" "net/http" "net/http/httptest" - "os" "path/filepath" "testing" "github.com/Wikid82/charon/backend/internal/services" "github.com/gin-gonic/gin" + "gorm.io/driver/sqlite" + "gorm.io/gorm" ) +// createValidSQLiteDB creates a minimal valid SQLite database for backup testing +func createValidSQLiteDB(t *testing.T, dbPath string) error { + t.Helper() + db, err := gorm.Open(sqlite.Open(dbPath), &gorm.Config{}) + if err != nil { + return err + } + sqlDB, err := db.DB() + if err != nil { + return err + } + defer func() { _ = sqlDB.Close() }() + + // Create a simple table to make it a valid database + return db.Exec("CREATE TABLE IF NOT EXISTS test (id INTEGER PRIMARY KEY, data TEXT)").Error +} + // Use a real BackupService, but point it at tmpDir for isolation func TestBackupHandlerQuick(t *testing.T) { gin.SetMode(gin.TestMode) tmpDir := t.TempDir() - // prepare a fake "database" so CreateBackup can find it + // Create a valid SQLite database for backup operations dbPath := filepath.Join(tmpDir, "db.sqlite") - if err := os.WriteFile(dbPath, []byte("db"), 0o600);
