23-24: Consider wrapping URLs in angle brackets or code blocks.The bare URLs trigger markdown linting warnings. While functional, wrapping them improves markdown compliance.
Apply this diff to address the linting warnings:

.github/workflows/ci.yml (1)
39-42: Consider running client and server tests in parallel.The
needs: server-testscreates a sequential dependency, increasing total CI time. Since these are independent unit/integration tests, they could run in parallel for faster feedback.Remove the
needsfield to run tests concurrently:client-tests: name: Client tests (conditional) runs-on: ubuntu-latest - needs: server-tests steps:server/market-trading-service/src/core/services/__tests__/MarketDataService.test.ts (2)
7-21: Consider adding type safety to the simulator mock.The
mockSimulatoris typed asany, which bypasses TypeScript's type checking. Consider creating a proper mock type or usingjest.Mocked<IPriceSimulator>for better type safety and IDE support.let service: MarketDataService; let mockRepo: jest.Mocked<ITickerRepository>; - let mockSimulator: any; + let mockSimulator: jest.Mocked<IPriceSimulator>; beforeEach(() => { mockRepo = { findAll: jest.fn(), findBySymbol: jest.fn(), save: jest.fn(), update: jest.fn(), }; mockSimulator = { start: jest.fn(), stop: jest.fn(), + stopAll: jest.fn(), generateHistoricalData: jest.fn(), };
4-53: Test coverage is incomplete for MarketDataService.The test suite covers
getAllTickers,getTicker, and null handling, but theMarketDataServicealso hasstartSimulation,getHistoricalData, andstopSimulationmethods that lack test coverage. Adding tests for these methods would improve confidence in the service behavior.Would you like me to generate test cases for the missing methods?
server/market-trading-service/src/infrastructure/repositories/__tests__/TickerRepository.test.ts (1)
3-56: Consider adding edge case tests.The test suite covers happy paths but could benefit from additional edge cases:
- Testing
findBySymbolwith a non-existent symbol- Testing case sensitivity (e.g., "aapl" vs "AAPL")
- Testing
updatewith a non-existent tickerExample additions:
it("should return null for non-existent symbol", async () => { const ticker = await repository.findBySymbol("NONEXISTENT"); expect(ticker).toBeNull(); }); it("should handle case-insensitive symbol lookup", async () => { const ticker = await repository.findBySymbol("aapl"); expect(ticker).toBeDefined(); expect(ticker?.symbol).toBe("AAPL"); });server/market-trading-service/src/api/controllers/__tests__/TickerController.test.ts (3)
18-18: Unused mock method: getQuote.The
getQuotemethod is included in the mock service but is never used in any test. Consider removing it to keep the mock minimal and focused.mockService = { getAllTickers: jest.fn(), getTicker: jest.fn(), getHistoricalData: jest.fn(), - getQuote: jest.fn(), };
6-55: Consider adding test coverage for the getHistoricalData endpoint.Based on the relevant code snippets, the
TickerControllerhas agetHistoricalDatamethod that handlesGET /api/tickers/:symbol/history, but there's no test for this endpoint. Adding test coverage would ensure the historical data endpoint works correctly.Example test to add:
it("GET /api/tickers/:symbol/history should return historical data", async () => { const mockHistoricalData = [ { date: "2024-01-01", price: 100 }, { date: "2024-01-02", price: 105 }, ]; mockService.getHistoricalData.mockResolvedValue(mockHistoricalData); const response = await request(app) .get("/api/tickers/AAPL/history?days=7") .expect(200); expect(response.body.success).toBe(true); expect(response.body.data).toEqual(mockHistoricalData); expect(mockService.getHistoricalData).toHaveBeenCalledWith("AAPL", 7); });
6-55: Consider adding error handling tests.The test suite doesn't include scenarios where the service throws errors. Adding tests for error cases would improve confidence in the error handling middleware.
Example error test:
it("GET /api/tickers should handle service errors", async () => { mockService.getAllTickers.mockRejectedValue(new Error("Service error")); const response = await request(app).get("/api/tickers").expect(500); expect(response.body.success).toBe(false); });

Verify coverage exclusions are intentional.
The coverage configuration excludes src/server.ts and all index.ts files. Ensure this is intentional, particularly for src/index.ts which contains the main application entry point and was modified in this PR. Consider whether entry point logic should be tested or if the exclusion is appropriate.

Remove !src/server.ts from coverage exclusion and reconsider excluding src/index.ts.
server.tsdoes not exist insrc/, so the!src/server.tsexclusion is unnecessary and should be removed.src/index.tscontains substantial application setup logic (middleware configuration, error handlers, graceful shutdown, process signal handlers), not just re-exports. The!src/**/index.tspattern excludes it from coverage; consider whether this logic should be tested or refactored into separately testable modules.
🤖 Prompt for AI Agents
In server/market-trading-service/jest.config.ts around lines 8 to 9, the
coverage exclusions include "!src/server.ts" which is a non-existent path and
should be removed, and the pattern "!src/**/index.ts" currently excludes index
files (including src/index.ts) that contain substantive app setup; remove the
"!src/server.ts" entry and reevaluate or remove the "!src/**/index.ts" exclusion
so src/index.ts is included in coverage (or instead refactor the setup logic
into testable modules and only exclude trivial re-export index files).

The update test may not validate persistence correctly.
The test retrieves a ticker from the repository (which returns a reference to the object in the Map), mutates it directly, then calls update. Since JavaScript objects are passed by reference, the ticker in the Map is already modified before update() is called. This means the test would pass even if the update() method was a no-op.
Consider this refactor to properly test the update method:
it("should update existing ticker", async () => {
const ticker = await repository.findBySymbol("AAPL");
if (ticker) {
- ticker.price = 200;
- await repository.update(ticker);
+ const updatedTicker = { ...ticker, price: 200 };
+ await repository.update(updatedTicker);
const updated = await repository.findBySymbol("AAPL");
expect(updated?.price).toBe(200);
}
});This creates a new object for the update, ensuring the test validates that the update method actually persists changes rather than just mutating an existing reference.

In
server/market-trading-service/src/infrastructure/repositories/__tests__/TickerRepository.test.ts
around lines 46 to 56, the test mutates the object returned by findBySymbol and
then calls update, which only validates in-memory reference mutation rather than
persistence; instead, assert existence of the fetched ticker, create a new
ticker object (clone the fetched object and set price = 200) and pass that new
object to repository.update, then re-fetch from the repository and assert the
persisted price is 200 so the test verifies update() actually persists changes
rather than relying on reference mutation.

25-36: Consider typing the mock instead of suppressing errors.The
@ts-expect-errorsuppressions work but could be improved with proper typing.Apply this diff to properly type the console.error mock:
describe("useTradingData", () => { let originalFetch: any; + let consoleErrorMock: jest.SpyInstance; beforeEach(() => { originalFetch = global.fetch; - jest.spyOn(console, "error"); - // @ts-expect-error jest.spyOn adds this functionallity - console.error.mockImplementation(() => null); + consoleErrorMock = jest.spyOn(console, "error").mockImplementation(() => null); }); afterEach(() => { global.fetch = originalFetch; - // @ts-expect-error jest.spyOn adds this functionallity - console.error.mockRestore(); + consoleErrorMock.mockRestore(); });client/trading-dashboard/components/__tests__/PriceChart.test.tsx (1)
19-33: Consider using a more semantic query or test ID.While querying by className (
.animate-spin) works, it's brittle if styling changes. For better resilience:Option 1: Add a test ID to the Loader2 component:
// In PriceChart.tsx -<Loader2 className="animate-spin text-blue-600 w-10 h-10" /> +<Loader2 className="animate-spin text-blue-600 w-10 h-10" data-testid="price-chart-loader" />Then update the test:
-expect(container.querySelector(".animate-spin")).toBeInTheDocument(); +expect(screen.getByTestId("price-chart-loader")).toBeInTheDocument();Option 2: Query by role if the loader has accessible attributes, though icons typically don't have semantic roles.
client/trading-dashboard/jest.config.ts (1)
10-25: Remove redundant transform configuration.The explicit
transformconfig usingts-jestis unnecessary and potentially problematic when usingnext/jest. Next.js automatically configures TypeScript transformation via its built-in SWC compiler, which is faster and ensures consistency between test and runtime environments. The explicitts-jesttransform overrides this behavior.Apply this diff to remove the redundant configuration:
const config: Config = { coverageProvider: "v8", testEnvironment: "jsdom", // Setup testing-library setupFilesAfterEnv: ["<rootDir>/jest.setup.ts"], // Map path alias moduleNameMapper: { "^@/(.*)$": "<rootDir>/$1", }, - - // Transform TS/TSX using ts-jest - transform: { - "^.+\\.(ts|tsx)$": ["ts-jest", { tsconfig: "<rootDir>/tsconfig.json" }], - }, };The
next/jestwrapper will handle TypeScript transformation automatically.

🧩 Analysis chain
Verify timestamp format compatibility with Recharts.
The makeData helper creates Date objects for the timestamp field. Recharts typically expects timestamps as numbers (milliseconds since epoch) or ISO strings, not Date objects. While Recharts may handle Date objects in some cases, using numeric timestamps is more reliable.
Consider this safer implementation:
const makeData = (points = 5) => {
const now = Date.now();
return Array.from({ length: points }).map((_, i) => ({
- timestamp: new Date(now - (points - i) * 3600 * 1000),
+ timestamp: now - (points - i) * 3600 * 1000,
price: 100 + i * 2,
volume: 1000 + i * 10,
open: 100 + i * 1.5,
high: 100 + i * 2.5,
low: 100 + i * 0.5,
close: 100 + i * 2,
}));

🌐 Web query:
Does Recharts AreaChart support Date objects as timestamp values in dataKey?
💡 Result:
Short answer: Yes — you can put JS Date objects in your chart data and use them as the X-axis/dataKey, but some Recharts APIs expect primitive string|number values, so you may run into features that require converting the Date to a timestamp or formatted string.
Details:
- Recharts will pass your data value (a Date object) to XAxis tickFormatter/Tooltip, so formatting functions like moment/date-fns can consume it. [1][4]
- However, some props and components (e.g., ReferenceLine.x, and internal matching logic) are typed/implemented to accept number|string and will error or fail to match when given a Date; several GitHub issues/discussions recommend converting Dates to numbers/ISO strings for full compatibility. [5][2]
- Common practice: store x values as timestamps (ms) or ISO strings in data, then use tickFormatter to render human‑readable dates. This gives the most consistent behavior across Recharts features. [7][4]

The review correctly identifies a timestamp compatibility issue. However, the problem is broader than the test file alone:
- Type definition (
types/index.ts:15): Definestimestamp: Date - Production data (
lib/utils.ts:45): Createsnew Date(...)objects matching the type - Component usage (
PriceChart.tsx:137, 138): Callsnew Date(time).toLocaleDateString(...), expecting numeric timestamps - Test data (
PriceChart.test.tsx:9): Mirrors production, creating Date objects
While new Date(dateObject) technically works via valueOf(), it's inefficient and fragile. To properly fix this:
- Change
HistoricalData.timestampfromDatetonumber(milliseconds) - Update production data generator (
lib/utils.ts:45) to removenew Date()wrapper - Update test data (
PriceChart.test.tsx:9) as suggested in the review
Without coordinating these changes, the type definition and actual data structure will remain misaligned with component expectations.

In client/trading-dashboard/components/__tests__/PriceChart.test.tsx around
lines 6-17 and in the related files types/index.ts (line ~15) and lib/utils.ts
(line ~45), the timestamp is currently modeled and produced as a Date object
while the component expects a numeric epoch (milliseconds); change the
HistoricalData.timestamp type from Date to number in types/index.ts, update the
production data generator in lib/utils.ts to return timestamp as a number (use
Date.now() or date.getTime() instead of new Date(...)), and modify the test
helper in PriceChart.test.tsx to set timestamp to a numeric value (milliseconds)
so types, production code, and tests all align with the component's numeric
timestamp usage.

client/trading-dashboard/components/__tests__/TickerGrid.test.tsx (1)
10-125: Consider adding error handling test coverage.The current test suite covers loading and success states well. Consider adding a test for fetch failure scenarios to ensure error states are handled gracefully.
Example test to add:
it("handles fetch errors gracefully", async () => { (global.fetch as jest.Mock).mockRejectedValueOnce( new Error("Network error") ); render( <QueryClientProvider client={queryClient}> <TickerGrid /> </QueryClientProvider> ); await waitFor(() => { // Assert error message or fallback UI is displayed expect(screen.queryByRole("status")).not.toBeInTheDocument(); }); });client/trading-dashboard/components/__tests__/Hero.test.tsx (1)
36-41: Optional: Consider testing via data-testid instead of class name.Testing CSS classes like
bg-gradient-to-brcan be brittle if styling changes. Since you addeddata-testid="hero"to the component, consider testing structural elements via semantic queries or test IDs rather than implementation details like class names.Example alternative:
- it("has proper section structure with gradient background", () => { - const { container } = render(<Hero />); - - const section = container.querySelector("section"); - expect(section).toHaveClass("bg-gradient-to-br"); - }); + it("renders the hero section", () => { + render(<Hero />); + + expect(screen.getByTestId("hero")).toBeInTheDocument(); + });client/trading-dashboard/components/__tests__/NewsFeed.test.tsx (1)
69-74: Optional: Testing CSS classes couples tests to implementation details.Similar to the Hero tests, asserting on CSS class names like
bg-secondary/30makes tests brittle. Consider focusing on semantic structure or add a data-testid to test the section's presence instead.client/trading-dashboard/lib/utils.test.ts (2)
3-7:formatCurrencytests are aligned; consider a slightly stricter tiny-decimal assertionThe expectations here match the current
formatCurrencyimplementation and typical UI usage. If you want to tighten the tiny-decimal check, you could anchor the regex or assert the full string (e.g.toBe("$0.000123")) so it fails if formatting ever adds/remove extra digits.
9-12: Validate non-abbreviated formatting style and extend coverage if usefulThese expectations match the current
formatLargeNumberlogic (no thousands separator on the non-abbreviated path). Two follow-ups to consider:
- If visual consistency with
formatCurrencyis desired, you may want$2,000.00instead of$2000.00. If the current style is intentional, no change needed.- For robustness, you could add tests for the
B/Tbranches and boundary values (e.g. just below/above 1e6, 1e9, 1e12).client/trading-dashboard/cypress/e2e/home.cy.ts (1)
1-6: LGTM - Good starting point for E2E testing.The test correctly uses Cypress's built-in retry logic with
.should("be.visible")to handle async rendering. This is a solid foundation for E2E coverage.Consider enhancing test robustness with data-testid attributes:
describe("Home page", () => { it("loads and shows hero text", () => { cy.visit("/"); - cy.contains("Live Market Data").should("be.visible"); + cy.get('[data-testid="hero-title"]').should("be.visible").and("contain", "Live Market Data"); }); });This makes tests more resilient to text changes and internationalization.

13-17: LGTM! Proper accessibility enhancement.The addition of
aria-busy="true"androle="status"attributes follows accessibility best practices for loading indicators, making the loading state properly announced to screen readers.client/trading-dashboard/components/__tests__/TickerGrid.test.tsx (6)
1-9: LGTM! Clean test setup.The imports and global fetch mock are properly configured for testing components that use React Query and fetch API.
10-22: LGTM! Proper test isolation.The QueryClient configuration with
retry: falseand mock clearing inbeforeEachensures fast, isolated, and predictable tests.
24-36: LGTM! Validates accessibility enhancement.This test correctly verifies the loading state and validates the
role="status"attribute added to LoadingSpinner.tsx, ensuring the accessibility improvement works as expected.
38-84: LGTM! Comprehensive data fetch test.The test properly mocks the fetch response and validates that ticker data is rendered correctly, checking both symbols and company names.
86-104: LGTM! Validates static content rendering.This test ensures the section title and description are displayed correctly, independent of the data state.
106-125: LGTM! Grid layout validation looks good.The test correctly verifies that multiple ticker cards render in a grid structure. Using
querySelectorfor the grid element is acceptable here since you're validating the structure rather than user-facing content.client/trading-dashboard/components/Hero.tsx (1)

6-13: LGTM! Proper timer management.The fake timer setup in
beforeEachand cleanup inafterEachcorrectly stabilizes tests for components with time-based behavior.client/trading-dashboard/app/page.tsx (1)
5-14: Verify: Was async data fetching intentionally removed?The conversion from async to synchronous removes the ability to fetch data in this Server Component. While this simplifies testing, ensure that:
- No data fetching was previously happening in this component
- If data fetching is needed in the future, consider using proper test mocking strategies rather than modifying production code for testability
The comment indicates this was done "so Jest can render it," but Next.js 16 with React 19 should support testing async Server Components with proper setup.
client/trading-dashboard/app/__tests__/page.test.tsx (2)
4-17: LGTM! Proper component mocking pattern.The mocks are correctly structured with
__esModule: trueand provide simple test doubles for the child components. The comment on line 3 helpfully explains the importance of mock order.
20-31: LGTM! Appropriate page-level tests.The tests verify both component composition and layout structure without being overly specific. This strikes a good balance for integration-level tests.

49-56: LGTM - Good observability on failure.Uploading Cypress videos and screenshots on failure is essential for debugging flaky tests in CI.
36-48: Mock data fallback mechanism is correctly implemented and tested.The implementation properly handles the unreachable host scenario:
- When fetch to

- Error logging is suppressed in tests via
console.error.mockRestore()- Polling is throttled at
refetchInterval: 2000to avoid hammering the unreachable hostThe fallback logic is validated by the existing test case "falls back to MOCK_TICKERS when tickers fetch fails" in

In .github/workflows/e2e.yml around lines 30 to 34, the workflow builds the
Next.js client without exporting NEXT_PUBLIC_MARKET_TRADING_URL, so the public
env var set later in the Cypress step is not baked into the build; update the
"Install client deps & build" step to export NEXT_PUBLIC_MARKET_TRADING_URL
(e.g., set it in the run block or use env: for that job/step) so the value is
available at build time, and then remove the redundant
NEXT_PUBLIC_MARKET_TRADING_URL assignment from the Cypress step (around line 46)
since the built app will already have the correct value.

Fix formatting issues and standardize dark mode handling.
Multiple className strings contain double spaces and inconsistent dark mode class usage:
- Double spaces (lines 21, 22, 32): Remove extra whitespace for cleaner code
- Inconsistent dark mode (lines 22, 36): The component uses a dark theme by default (
bg-gray-900,bg-gray-800/60), but some elements conditionally applydark:prefix classes. Either commit to a dark-only theme or implement proper light/dark mode support consistently across all elements. - Long className strings (lines 28, 44): Consider using a utility like
