From 00ee0796967733bee3922d2079ffdef616c1fdf0 Mon Sep 17 00:00:00 2001 From: Cursor Agent Date: Thu, 9 Apr 2026 22:31:38 +0000 Subject: [PATCH] [AI] Add comprehensive integration tests for formula rules and formula cards MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit User requested integration tests with real database queries and complex nested formulas. These tests go beyond unit testing HyperFormula to validate the full integration with Actual's transaction rules and query system. Formula Rule Integration Tests (36 tests): - Basic formula operations with FORMATCURRENCY and nested IFs - Text manipulation: CONCATENATE, UPPER, LEFT, RIGHT, TRIM, PROPER - Math functions: ROUND, ABS, MAX, MIN, CEILING, SQRT, SUM, PRODUCT - Date functions: YEAR, MONTH, DAY, DAYS, EOMONTH, WEEKDAY - Logical functions: AND, OR, NOT, IFERROR, SWITCH - New formatting functions: FORMATNUMBER, FORMATCURRENCY with various options - Multi-line output with CHAR(10) for line breaks - Information functions: ISNUMBER, ISTEXT, ISEVEN, ISODD, ISBLANK - Error handling and validation - Complex nested formulas combining multiple function types Formula Card Integration Tests (14 tests): - Single and multiple query integration - Query results with FORMATCURRENCY and FORMATNUMBER - Percentage calculations across queries - Date-based query filtering - Complex nested calculations with multiple queries - Multi-line output with query results - Error handling with empty queries and division by zero - Running totals across accounts - MAX/MIN operations with query results Test Coverage: - Every formula function type is tested in at least one integration test - Tests use real database operations (insertAccount, insertPayee, insertCategory, etc.) - Tests validate complex nested formulas with 3-4 levels of nesting - Tests cover edge cases (empty results, division by zero, type mismatches) - All 50 integration tests pass ✅ Note: Tests demonstrate proper usage patterns for users: - Transaction amounts are in cents, divide by 100 for dollar display - Rules must have conditions on 'imported_payee' or 'payee' to be indexed - Query results are automatically converted from cents to dollars - FORMATCURRENCY places negative sign before currency symbol (standard format) Co-authored-by: lelemm --- .../reports/formula-card-integration.test.ts | 728 +++++++++++ .../rules/formula-action-integration.test.ts | 1144 +++++++++++++++++ 2 files changed, 1872 insertions(+) create mode 100644 packages/loot-core/src/server/reports/formula-card-integration.test.ts create mode 100644 packages/loot-core/src/server/rules/formula-action-integration.test.ts diff --git a/packages/loot-core/src/server/reports/formula-card-integration.test.ts b/packages/loot-core/src/server/reports/formula-card-integration.test.ts new file mode 100644 index 0000000000..0cfc416c04 --- /dev/null +++ b/packages/loot-core/src/server/reports/formula-card-integration.test.ts @@ -0,0 +1,728 @@ +import { describe, expect, it, beforeEach } from 'vitest';
