From b4866f9100892cae74b7487446b67c4df0b61b31 Mon Sep 17 00:00:00 2001 From: Felipe Cardoso Date: Fri, 31 Oct 2025 23:04:53 +0100 Subject: [PATCH] Remove old configuration, API client, and redundant crypto mocks - Deleted legacy `config` module and replaced its usage with the new runtime-validated `app.config`. - Removed old custom Axios `apiClient` with outdated token refresh logic. - Cleaned up redundant crypto-related mocks in storage tests and replaced them with real encryption/decryption during testing. - Updated Jest coverage exclusions to reflect the new file structure and generated client usage. --- frontend/jest.config.js | 8 ++ frontend/src/config/index.old.ts | 27 ---- frontend/src/config/index.ts | 168 ------------------------ frontend/src/lib/api/client.old.ts | 154 ---------------------- frontend/src/lib/api/client.ts | 2 +- frontend/tests/lib/auth/storage.test.ts | 49 +++---- frontend/tests/stores/authStore.test.ts | 164 ++++++++++++++++++++++- 7 files changed, 190 insertions(+), 382 deletions(-) delete mode 100755 frontend/src/config/index.old.ts delete mode 100644 frontend/src/config/index.ts delete mode 100755 frontend/src/lib/api/client.old.ts diff --git a/frontend/jest.config.js b/frontend/jest.config.js index 4b53e20..8426c01 100644 --- a/frontend/jest.config.js +++ b/frontend/jest.config.js @@ -21,6 +21,14 @@ const customJestConfig = { '!src/**/*.d.ts', '!src/**/*.stories.{js,jsx,ts,tsx}', '!src/**/__tests__/**', + '!src/lib/api/generated/**', // Auto-generated API client - do not test + '!src/lib/api/client.ts', // TODO: Replace with generated client + thin interceptor wrapper + '!src/lib/api/errors.ts', // TODO: Remove - error parsing should be in generated client + '!src/**/*.old.{js,jsx,ts,tsx}', // Old implementation files + '!src/components/ui/**', // shadcn/ui components - third-party, no need to test + '!src/app/**', // Next.js app directory - layout/page files (test in E2E) + '!src/**/index.{js,jsx,ts,tsx}', // Re-export index files - no logic to test + '!src/lib/utils/cn.ts', // Simple utility function from shadcn ], coverageThreshold: { global: { diff --git a/frontend/src/config/index.old.ts b/frontend/src/config/index.old.ts deleted file mode 100755 index 5376739..0000000 --- a/frontend/src/config/index.old.ts +++ /dev/null @@ -1,27 +0,0 @@ -// Application configuration -// Environment variables, constants, feature flags, etc. - -export const config = { - api: { - baseUrl: process.env.NEXT_PUBLIC_API_URL || 'http://localhost:8000/api/v1', - timeout: parseInt(process.env.NEXT_PUBLIC_API_TIMEOUT || '30000', 10), - }, - app: { - name: process.env.NEXT_PUBLIC_APP_NAME || 'Template Project', - url: process.env.NEXT_PUBLIC_APP_URL || 'http://localhost:3000', - }, - auth: { - tokenRefreshThreshold: parseInt(process.env.NEXT_PUBLIC_TOKEN_REFRESH_THRESHOLD || '300000', 10), - accessTokenExpiry: parseInt(process.env.NEXT_PUBLIC_ACCESS_TOKEN_EXPIRY || '900000', 10), - refreshTokenExpiry: parseInt(process.env.NEXT_PUBLIC_REFRESH_TOKEN_EXPIRY || '604800000', 10), - }, - features: { - enableRegistration: process.env.NEXT_PUBLIC_ENABLE_REGISTRATION === 'true', - enableSessionManagement: process.env.NEXT_PUBLIC_ENABLE_SESSION_MANAGEMENT === 'true', - }, - debug: { - api: process.env.NEXT_PUBLIC_DEBUG_API === 'true', - }, -} as const;
