Add tests, fix DB schema, add docs by PankajSingh34 · Pull Request #243 · csxark/Wealth-Vault

PankajSingh34 · 2026-02-05T16:57:13Z

Add comprehensive Jest tests and testing docs, fix schema syntax, and install missing deps. This commit adds four new test suites (analytics, categories, goals, financialCalculations) with ~100+ assertions to bootstrap testing; includes TEST_SETUP_COMPLETE.md and FIRST_CONTRIBUTION_GUIDE.md. Fixes a schema bug (rename inactivity threshold → inactivityThreshold) and adds subscriptions, subscriptionUsage, and cancellationSuggestions tables to backend/db/schema.js. package.json and lock updated to include testing and mailing dependencies (e.g. Jest, nodemailer). Some new tests are passing (17) while ~15 need minor property-name adjustments documented in the added guides.

Pull request overview

This PR adds comprehensive Jest testing infrastructure to the Wealth Vault backend, fixes a critical database schema syntax error, adds three new subscription-related database tables, and installs nodemailer as a dependency. The changes include four new test suites (analytics, categories, goals, financialCalculations) with 100+ assertions, though many tests have critical property name mismatches that cause test failures.

Changes:

Fixed schema syntax bug: inactivity threshold → inactivityThreshold in inheritanceRules table
Added three new database tables: subscriptions, subscriptionUsage, and cancellationSuggestions
Added nodemailer ^8.0.0 dependency and updated package-lock.json
Created four new test files with 100+ test assertions
Added two documentation files: TEST_SETUP_COMPLETE.md and FIRST_CONTRIBUTION_GUIDE.md

+      const recurringExpenses = 1500;
+      const monthlyIncome = 5000;
+
+      const prediction = predictCashFlow(monthlyData, recurringExpenses, monthlyIncome);


The test's recurringExpenses parameter is a number (1500), but the actual predictCashFlow implementation expects an array of objects with an amount property (line 310 of financialCalculations.js): const recurringTotal = recurringExpenses.reduce((sum, expense) => sum + expense.amount, 0);

The test should pass an array like [{ amount: 1500 }] instead of just 1500.

The hardcoded file path is specific to one developer's machine and will not work for anyone else. This should be replaced with a relative path or removed entirely. Users can determine their current directory with pwd and don't need to see someone else's absolute path.

Replace with: cd backend (assuming users are in the project root)

+# If you haven't forked yet, fork the repo on GitHub first
+# Then add your fork as a remote
+git remote add origin https://github.com/YOUR_USERNAME/Wealth-Vault.git
+
+# Push to your fork


This instruction assumes the user hasn't forked the repository yet and provides a generic remote URL. However, if this guide is being committed to the main repository, the instructions are potentially misleading:

Users should fork the original repository first (github.com/PankajSingh34/Wealth-Vault)

Clone their fork (not the original)

Add the original as 'upstream' (not 'origin')

'origin' should already exist pointing to their fork

The typical Git workflow for contributing to open source is:

# Fork on GitHub first, then: git clone https://github.com/YOUR_USERNAME/Wealth-Vault.git cd Wealth-Vault git remote add upstream https://github.com/PankajSingh34/Wealth-Vault.git git checkout -b fixes # Make changes, then: git push origin fixes

Suggested change

# If you haven't forked yet, fork the repo on GitHub first

# Then add your fork as a remote

git remote add origin https://github.com/YOUR_USERNAME/Wealth-Vault.git

# Push to your fork

# Make sure you've forked the repo on GitHub and cloned *your fork*:

# https://github.com/YOUR_USERNAME/Wealth-Vault.git

# Optional (do this once): add the original repo as "upstream"

+    });
+  });


The test expectations don't match the actual implementation. The calculateFinancialHealthScore function returns properties: overallScore, rating, recommendation, breakdown, weights, and timestamp, but the test expects category which doesn't exist.

The correct property name is rating (not category). The rating values are: 'Excellent', 'Good', 'Fair', or 'Needs Improvement' (note the capitalization and different value for scores < 40). The test expects 'excellent' (lowercase) which won't match.

The mocking strategy in these new test files (jest.unstable_mockModule) is inconsistent with the existing test patterns in the codebase. The existing tests in backend/__tests__/routes/auth.test.js and backend/__tests__/routes/expenses.test.js directly import the routers without mocking the database layer, which is simpler and more maintainable.

The jest.unstable_mockModule API is also marked as "unstable" in its name, indicating it may change in future Jest versions. Consider following the existing pattern used in the codebase:

Import routers directly without complex mocking

Use simple status code checks like expect([200, 500]).toContain(res.status)

Focus on testing the API contract rather than implementation details

This will make tests more maintainable and consistent with the project's established testing conventions.

The test expectations don't match the actual implementation. According to the source code in backend/utils/financialCalculations.js, the calculateEmergencyFundAdequacy function returns properties: monthsCovered, adequacy, and score, but these tests expect months and status.

Expected properties should be:

monthsCovered (not months)

adequacy (not status)

score (missing from tests)

Additionally, the adequacy values differ from what's tested. The actual implementation returns:

'excellent' for >= 6 months (not 'adequate')

'good' for >= 3 months (not 'needs_improvement')

'fair' for >= 1 month (not 'critical')

'insufficient' for < 1 month

The test expectations don't match the actual implementation. The calculateBudgetAdherence function returns properties: adherence, variance, status, and percentage, but the test expects adherencePercentage (which doesn't exist).

The correct property name is percentage (which represents actual spending as a percentage of budget). Also note that adherence represents how much under/over budget you are as a percentage, not the spending percentage.

The status values also differ from what's tested. The actual implementation returns:

'excellent' for adherence >= 10%

'good' for adherence >= 0%

'fair' for adherence >= -10%

'poor' for adherence < -10%

The test expects 'over_budget' which doesn't exist in the implementation.

The test expectations don't match the actual implementation. The calculateGoalProgress function returns properties: averageProgress, onTrackCount, totalGoals, score, and goals, but the test expects totalProgress which doesn't exist.

The correct property name is averageProgress (not totalProgress). All references to totalProgress in these tests should be changed to averageProgress.

The test expectations don't match the actual implementation. The predictCashFlow function returns properties: predictedExpenses, predictedIncome, predictedBalance, trend, trendAmount, confidence, volatility, recurringExpensesTotal, and warning, but the test expects predictedSurplus which doesn't exist.

The test uses monthlyData objects with month, income, and expenses properties, but the actual predictCashFlow implementation expects objects with a total property (line 289 of financialCalculations.js). The function calculates: const avgExpenses = monthlyData.reduce((sum, month) => sum + month.total, 0) / monthlyData.length;

The test data should be restructured to have a total property representing the expenses, or the actual parameter should use the expenses property if that's intended.
