Add Schaad.Accounting.Tests (xUnit + NSubstitute + Shouldly, net9.0)
wired into Accounting.sln with a direct Reference to
Schaad.Finance.Api.dll so it flows into the test binary.
Naming convention: file/class is <Subject>TestShould, each test method
is DoThisWhenThat. Reads as a sentence:
"ViewService test should sum activa and passiva totals separately when
getting balance view". All assertions use Shouldly (.ShouldBe,
.ShouldBeNull, .ShouldContain, ...) rather than xUnit Assert.*.
38 tests across seven files:
- ViewServiceTestShould: balance math (activa/passiva totals, per-
account balance from start balance + credits - debits, FX conversion
to CHF) and bank-transaction auto-matching (booking-rule text,
value-matching preference, same-accounts-last-month fallback,
open-transaction filter).
- TransactionRepositoryTestShould: FX round-trip against a temp XML
directory, unknown-id -> null, and the mutation-on-read regression
from PR A (a second Get on the same FX transaction used to divide
by FxRate again).
- FormattingTestShould: Swiss thousands separator, two-decimal
rounding, culture independence.
- RepositoryCacheTestShould: loader called once, per-key isolation,
invalidation forces reload, case-insensitive keys.
- AccountRepositoryTestShould: id assignment, in-place update,
currency defaulting, delete, bank-account lookup, bank-balance
update, and constructor re-run against an existing file.
- ChartServiceTestShould: honours settingsService.GetYear() without
mutating it (locks in PR E), account vs sub-class grouping
heuristic, skips empty accounts.
- FileServiceTestShould: CSV header + running balance for debit and
credit lines, ordering by BookingDate/ValueDate/Value, no in-place
value mutation (locks in PR A).
CLAUDE.md gains a `dotnet test` line. IMPROVEMENT_PLAN.md notes that
this landed as three PRs (G, H, I) and was squashed on request.
Also add `*.DotSettings.user` to .gitignore so Rider's per-user
solution settings don't get accidentally staged.
