From 052f5169c5bf12bb06f3e1730b5762798b3e07ad Mon Sep 17 00:00:00 2001 From: Tiago Yamamoto Date: Wed, 24 Dec 2025 16:20:56 -0300 Subject: [PATCH] test(auth): add comprehensive auth tests with 98.6% coverage Backend Tests Added: - auth_middleware_test.go: 25+ tests for HeaderAuthGuard, OptionalHeaderAuthGuard, RequireRoles, TenantGuard, ExtractRoles, hasRole (100% coverage) - cors_middleware_test.go: 7 tests for CORS origin validation (100% coverage) - jwt_service_test.go: expanded with expiration parsing, wrong signing method tests (94.4% coverage) Features: - Maximum console.log/fmt.Printf output for debugging - Tests for JWT from header and cookie fallback - Tests for role-based access (case-insensitive) - Tests for tenant enforcement - Tests for token expiration parsing (7d, 2h, invalid formats) Total backend auth coverage: 98.6% --- backend/go.mod | 1 + backend/go.sum | 1 + .../api/middleware/auth_middleware_test.go | 601 ++++++++++++++++++ .../api/middleware/cors_middleware_test.go | 205 ++++++ .../infrastructure/auth/jwt_service_test.go | 138 +++- 5 files changed, 944 insertions(+), 2 deletions(-) create mode 100644 backend/internal/api/middleware/auth_middleware_test.go create mode 100644 backend/internal/api/middleware/cors_middleware_test.go diff --git a/backend/go.mod b/backend/go.mod index 41c1826..fa7ea14 100644 --- a/backend/go.mod +++ b/backend/go.mod @@ -46,6 +46,7 @@ require ( github.com/go-openapi/swag/typeutils v0.25.4 // indirect github.com/go-openapi/swag/yamlutils v0.25.4 // indirect github.com/pmezard/go-difflib v1.0.0 // indirect + github.com/stretchr/objx v0.1.0 // indirect github.com/swaggo/files/v2 v2.0.2 // indirect go.yaml.in/yaml/v3 v3.0.4 // indirect golang.org/x/mod v0.30.0 // indirect diff --git a/backend/go.sum b/backend/go.sum index 6ce6f45..bddc1bc 100755 --- a/backend/go.sum +++ b/backend/go.sum @@ -81,6 +81,7 @@ github.com/lib/pq v1.10.9 h1:YXG7RB+JIjhP29X+OtkiDnYaXQwpS4JEWq7dtCCRUEw= github.com/lib/pq v1.10.9/go.mod h1:AlVN5x4E4T544tWzH6hKfbfQvm3HdbOxrmggDNAPY9o= github.com/pmezard/go-difflib v1.0.0 h1:4DBwDE0NGyQoBHbLQYPwSUPoCMWR5BEzIk/f1lZbAQM= github.com/pmezard/go-difflib v1.0.0/go.mod h1:iKH77koFhYxTK1pcRnkKkqfTogsbg7gZNVY4sRDYZ/4= +github.com/stretchr/objx v0.1.0 h1:4G4v2dO3VZwixGIRoQ5Lfboy6nUhCyYzaqnIAPPhYs4= github.com/stretchr/objx v0.1.0/go.mod h1:HFkY916IF+rwdDfMAkV7OtwuqBVzrE8GR6GFx+wExME= github.com/stretchr/testify v1.7.0 h1:nwc3DEeHmmLAfoZucVR881uASk0Mfjw8xYJ99tb5CcY= github.com/stretchr/testify v1.7.0/go.mod h1:6Fq8oRcR53rry900zMqJjRRixrwX3KX962/h/Wwjteg= diff --git a/backend/internal/api/middleware/auth_middleware_test.go b/backend/internal/api/middleware/auth_middleware_test.go new file mode 100644 index 0000000..9fe015e --- /dev/null +++ b/backend/internal/api/middleware/auth_middleware_test.go @@ -0,0 +1,601 @@ +package middleware + +import ( + "context" + "fmt" + "net/http" + "net/http/httptest" + "testing" + + "github.com/stretchr/testify/assert" + "github.com/stretchr/testify/mock" +) + +// MockAuthService implements ports.AuthService for testing +type MockAuthService struct { + mock.Mock +} + +func (m *MockAuthService) ValidateToken(token string) (map[string]interface{}, error) { + fmt.Printf("[TEST LOG] ValidateToken called with token: '%s...'\n", token[:min(20, len(token))]) + args := m.Called(token) + if args.Get(0) == nil { + return nil, args.Error(1) + } + return args.Get(0).(map[string]interface{}), args.Error(1) +} + +func (m *MockAuthService) GenerateToken(userID, tenantID string, roles []string) (string, error) { + fmt.Printf("[TEST LOG] GenerateToken called: userID=%s, tenantID=%s, roles=%v\n", userID, tenantID, roles) + args := m.Called(userID, tenantID, roles) + return args.String(0), args.Error(1) +} + +func (m *MockAuthService) HashPassword(password string) (string, error) { + fmt.Printf("[TEST LOG] HashPassword called\n") + args := m.Called(password) + return args.String(0), args.Error(1) +} + +func (m *MockAuthService) VerifyPassword(hash, password string) bool { + fmt.Printf("[TEST LOG] VerifyPassword called\n") + args := m.Called(hash, password) + return args.Bool(0) +} + +// ============================================================================ +// TestHeaderAuthGuard -
