# Step 7: Tests & Validation
|
|
|
|
Create tests in `tests/Duempelkas.Tests/`.
|
|
|
|
## Test 1: Transfer Consistency (`TransferServiceTests.cs`)
|
|
|
|
### Scenario: CreateTransfer_CreatesLinkedExpenseAndIncome
|
|
Given:
|
|
- Account A and Account B exist
|
|
- Both have AccountYear for 2026 with OpeningBalance = 0
|
|
|
|
When:
|
|
- A transfer of 100.00 EUR is created from A/2026 to B/2026 with title "Test Transfer"
|
|
|
|
Then:
|
|
- Exactly 2 entries are created in the database
|
|
- Entry on A is `EntryType.Expense`, amount = 100.00
|
|
- Entry on B is `EntryType.Income`, amount = 100.00
|
|
- Both entries share the same date and title
|
|
- Exactly 1 `TransferLink` exists linking the two entries
|
|
- Account A total balance = -100.00
|
|
- Account B total balance = +100.00
|
|
|
|
### Scenario: DeleteTransfer_RemovesBothSides
|
|
Given:
|
|
- A transfer exists between A and B
|
|
|
|
When:
|
|
- The source entry is deleted via `IEntryService.DeleteEntryAsync`
|
|
|
|
Then:
|
|
- Both entries are removed
|
|
- The TransferLink is removed
|
|
- Account A and B balances return to 0
|
|
|
|
## Test 2: Yearly Statement Calculation (`YearlyStatementCalculationTests.cs`)
|
|
|
|
### Scenario: YearlySummary_CalculatesCorrectTotals
|
|
Given:
|
|
- Account with Year 2026, OpeningBalance = 500.00
|
|
- Entries: Income 800.00, Income 400.00, Expense 200.00, Expense 250.00
|
|
|
|
Then:
|
|
- TotalIncome = 1200.00
|
|
- TotalExpense = 450.00
|
|
- YearlyMovement = 750.00
|
|
- ClosingBalance = 1250.00
|
|
|
|
### Scenario: YearlySummary_IncludesTransfersCorrectly
|
|
Given:
|
|
- Account A, Year 2026, OpeningBalance = 500.00
|
|
- Income entry: 1000.00
|
|
- Transfer out to Account B: 300.00 (creates Expense entry on A)
|
|
|
|
Then:
|
|
- A's TotalIncome = 1000.00
|
|
- A's TotalExpense = 300.00
|
|
- A's YearlyMovement = 700.00
|
|
- A's ClosingBalance = 1200.00
|
|
|
|
## Test Setup
|
|
- Use EF Core `InMemory` or SQLite in-memory (`Data Source=:memory:`) for test database.
|
|
- Wire up real service implementations against the test database.
|
|
- Use `FluentAssertions` for readable assertions.
|
|
- Arrange/Act/Assert pattern throughout.
|
|
|
|
## Manual Verification Checklist (as code comments)
|
|
1. Launch on Windows — app window opens with dashboard
|
|
2. Launch on Linux — app window opens (requires WebKit2GTK)
|
|
3. Create account → appears on dashboard with 0 balance
|
|
4. Add year 2026 with carryover 500 → year appears in selector
|
|
5. Add income/expense entries → table populates, balance updates
|
|
6. Create transfer between accounts → both sides appear with transfer badge
|
|
7. Export PDF → file saves, totals match on-screen values
|
|
8. Delete transfer → both sides removed, balances correct
