Subject: [PATCH 01/21] Add tests and extract isRouteAccessible helper

Add comprehensive unit tests for proxyConfig, vertex-config, useContextAwareRouting, api-routing, and utils to improve coverage and validate edge cases. Refactor useContextAwareRouting by extracting isRouteAccessible into a standalone exported helper and update the hook to call it with the sidebar config, making routing logic easier to test and reuse. Tests include environment mocking and logger stubs for validateProxyConfig and various cases for API URL resolution, path versioning, class name utilities, and elapsed duration calculations.

Subject: [PATCH 02/21] Add hook tests and test utilities

Add comprehensive unit tests for core hooks (useBannerWithDelay, useClipboard, useCohorts, useDevices, useGroups, usePermissions, useRecentlyVisited, useRoles, useServerSideTableState, useSites, useUserContext, useWindow). Introduce test helpers and mocks: renderWithProviders, renderHookWithProviders, createTestQueryClient, and setupStore (configuring relevant Redux slices). Also add simple test factories (device, organization, user) and various API/adapter/permission/banner mocks to standardize the testing environment and improve coverage for hook behavior.

Subject: [PATCH 03/21] Use combineReducers to create root reducer

Replace the inline reducer object with a combined `rootReducer` using Redux Toolkit's `combineReducers`. Adds the `combineReducers` import and constructs a single root reducer from user, sites, devices, grids, cohorts, and groups slices before passing it to `configureStore`. This centralizes reducer composition and makes extending or replacing reducers easier in tests and runtime.

Update useBannerWithDelay test to expect the banner payload to include severity: "info". The assertion in src/vertex/core/hooks/useBannerWithDelay.test.tsx now checks for { message: "Second", severity: "info" }, reflecting the banner payload change to include a default severity.

Subject: [PATCH 05/21] Add tests for shared and UI components

Add Vitest + React Testing Library unit tests for multiple shared and UI components. New tests cover shared components (ReusableButton, ReusableFileUpload, ReusableInputField, ReusableSelectInput, ReusableTable, ReusableToast, CardWrapper) and many UI primitives (accordion, alert, avatar, badge, banner, button, calendar, card, checkbox, combobox, command, date-picker, dialog, dropdown-menu, empty-state, form, input, label, popover, progress, select, skeleton, switch, tabs, textarea, tooltip). Tests assert accessibility roles, user interactions, and component states; and include necessary mocks for browser APIs (clipboard, PointerEvent, ResizeObserver, scrollIntoView) and app contexts (next/navigation, banner-context) to stabilize JSDOM test runs.

Subject: [PATCH 06/21] Add unit tests for UI components

Add comprehensive Vitest + React Testing Library unit tests for various UI components under src/vertex/components/ui. Tests cover ErrorBoundary, alert dialog, chart container, collapsible, custom dialog, forbidden error/page, hcaptcha widget, hover card, multi-select, pagination, permission tooltip, scroll area, select field, separator, sheet, sonner/toaster, stepper, table, and toast. Includes necessary test-time mocks/stubs (ResizeObserver, PointerEvent, next/navigation, react-redux, env constants, tooltip/provider, next-themes, use-toast) and uses userEvent for interaction tests to validate rendering and basic behaviors.

Subject: [PATCH 07/21] Update tests and remove ReusableTable defaultProps

Modify ReusableTable to use a plain <style> tag (remove styled-jsx) and remove the defaultProps block. Update several unit tests: ErrorBoundary test now prevents & cleans up window error events to avoid noisy logs; chart test imports vi, mocks recharts' ResponsiveContainer and wraps ChartContainer in a sized div to stabilize rendering; custom-dialog test adds Dialog title/description nodes; stepper test simplifies children to plain spans and removes unused StepTitle/StepDescription imports. These changes address test stability and clean up component defaults.

Subject: [PATCH 08/21] Add tests for network, onboarding, proxy, platform

Add comprehensive unit tests and test utilities for core services and utils. New tests cover network-service (axios/fetch flows, errors, timeouts), onboardingService (secureApiProxy patch calls), proxyClient (request forwarding, auth/api token injection, error handling), secureApiProxyClient (axios interceptors, token handling, response error behavior), and platform (Mac architecture detection fallbacks). Also add test factories (apiResponseFactory) for mocking Axios/Fetch responses and next-auth mocks (nextAuth) to simplify session and server-session stubbing.

 > **Note**: This changelog consolidates all recent improvements, features, and fixes to the AirQo Vertex frontend.
 
+## Version 2.0.8
+**Released:** June 28, 2026
+
+### Comprehensive Unit Testing & CI Integration
+
+Introduced a robust unit testing infrastructure using Vitest and React Testing Library, alongside comprehensive CI/CD pipeline integration. This release focuses on improving code quality, ensuring robust component rendering, and validating API proxy behavior through extensive boundary testing.
+
+<details>
+<summary><strong>Test Infrastructure & CI Integration (3)</strong></summary>
+
+- **Vitest & React Testing Library**: Replaced legacy test runners with a fast, modern Vitest setup configured to work seamlessly with Next.js App Router and absolute imports.
+- **CI/CD Pipeline**: Added dedicated GitHub Actions workflows for automated type checking (`tsc --noEmit`) and unit testing (`vitest run --coverage`) on pull requests.
+- **Testing Guidelines**: Introduced `TESTING.md` internal documentation to standardize component rendering, user-event interactions, and mocking strategies across the team.
+
+</details>
+
+<details>
+<summary><strong>UI & Shared Component Testing (3)</strong></summary>
+
+- **Core UI Components**: Achieved full coverage for over 30 shadcn/radix UI components (Dialogs, Accords, Tooltips, Buttons, Inputs, Forms, etc.) verifying accessibility and interaction states without snapshot testing.
+- **Shared Abstractions**: Extracted and tested shared wrappers including `ReusableTable`, `ReusableSelectInput`, `ReusableButton`, and `ReusableFileUpload`, ensuring robust prop forwarding and DOM nesting compliance.
+- **Warning Resolutions**: Proactively fixed React DOM nesting warnings (e.g., `<a>` cannot appear as a descendant of `<a>`) and accessibility label warnings across components during test implementation.
+
+</details>
+
+<details>
+<summary><strong>Service & API Boundary Testing (2)</strong></summary>
+
+- **Mock Factories**: Created `apiResponseFactory.ts` and NextAuth session mocks to simulate full HTTP environments locally without hitting live staging endpoints or needing `axios-mock-adapter`.
+- **Proxy Validation**: Validated both the Next.js App Router API handlers (`proxyClient`) and client-side Axios instances (`secureApiProxyClient`), verifying `JWT` vs `API_TOKEN` injection, error normalization, and custom event dispatching (`vertex-network-degraded`, `auth-token-expired`).
+

 ## Version 2.0.7
 **Released:** June 17, 2026

Subject: [PATCH 10/21] Tighten test typings and remove unused imports

Refactor multiple UI test files to improve TypeScript types and remove unused imports. Replaced broad any casts with stricter types (unknown, never, Record<string, unknown>, and React.ReactNode) including vi.importActual typing and mock component props. Unified MockPointerEvent assignment to window.PointerEvent as never and adjusted ReusableTable test to use String(val) and a never cast for columns. Also removed unused imports (AvatarImage, Banner variants, userEvent) and added typed Tooltip mocks to reduce TS errors and improve type safety across tests.

Subject: [PATCH 11/21] Add domMocks test utilities and update tests

Extract repeated JSDOM/window mock setup into a new test utility (src/vertex/test/utils/domMocks.ts) exposing setupPointerEventMock and setupResizeObserverMock. Replace inline MockPointerEvent/ResizeObserver and HTMLElement overrides across multiple UI tests (chart, combobox, date-picker, dialog, dropdown-menu, multi-select, popover, select) with imports and calls to the new utilities. The helpers install mocks in beforeAll and restore originals in afterAll to keep tests isolated and reduce duplication.

Subject: [PATCH 18/21] Ensure cleanup in ErrorBoundary test

Wrap render and assertions in a try/finally block so window error listener removal and console.error mock restoration always run. This prevents leaking global state and makes the ErrorBoundary test more robust if render or assertions throw.

+- **Core UI Components**: Added comprehensive tests for 30+ shadcn/radix UI components (Dialogs, Accords, Tooltips, Buttons, Inputs, Forms, etc.) verifying accessibility and interaction states without snapshot testing.
 - **Shared Abstractions**: Extracted and tested shared wrappers including `ReusableTable`, `ReusableSelectInput`, `ReusableButton`, and `ReusableFileUpload`, ensuring robust prop forwarding and DOM nesting compliance.
 - **Warning Resolutions**: Proactively fixed React DOM nesting warnings (e.g., `<a>` cannot appear as a descendant of `<a>`) and accessibility label warnings across components during test implementation.
