Add Bonanza Produce multi-invoice statement template

- Added multi-invoice template for Bonanza Produce with :multi and :multi-match? flags
- Template uses keywords for statement header to identify multi-invoice format
- Extracts invoice-number, date, customer-identifier (from RETURN line), and total
- Parses 4 invoices from statement PDF 13595522.pdf
- All tests pass (29 assertions, 0 failures, 0 errors)

- Added test: parse-bonanza-produce-statement-13595522
- Updated invoice-template-creator skill: emphasized test-first approach

# Testing Conventions Skill
This skill documents the testing conventions for `test/clj/auto_ap/`.
## Test Focus: User-Observable Behavior
**Primary rule**: Test user-observable behavior. If an endpoint or function makes a database change, verify the change by querying the database directly rather than asserting on markup.
**other rules**:
1. Don't test the means of doing work. For example, if there is a middleware that makes something available on a request, don't bother testing that wrapper.
2. prefer :refer testing imports, rather than :as reference
3. Prefer structured edits from clojure-mcp
### When to Assert on Database State
When testing an endpoint that modifies data:
1. Verify the database change by querying the entity directly
2. Use `dc/pull` or `dc/q` to verify the data was stored correctly
```clojure
;; CORRECT: Verify the database change directly
(deftest test-create-transaction
(let [result @(post-create-transaction {:amount 100.0})]
(let [entity (dc/pull (dc/db conn) [:db/id :transaction/amount] (:transaction/id result))]
(is (= 100.0 (:transaction/amount entity))))))
;; CORRECT: Verify response status and headers
(is (= 201 (:status response)))
(is (= "application/json" (get-in response [:headers "content-type"])))
;; CORRECT: Check for expected text content
(is (re-find #"Transaction created" (get-in response [:body "message"])))
```
### When Markup Testing is Acceptable
Markup testing (HTML/SSR response bodies) is acceptable when:
- Validating response status codes and headers
- Checking for presence/absence of specific text strings
- Verifying small, expected elements within the markup
- Testing SSR component rendering
```clojure
;; ACCEPTABLE: Response codes and headers
(is (= 200 (:status response)))
(is (= "application/json" (get-in response [:headers "content-type"])))
;; ACCEPTABLE: Text content within markup
(is (re-find #"Transaction found" response-body))
;; ACCEPTABLE: Small element checks
(is (re-find #">Amount: \$100\.00<" response-body))
```
### When to Avoid Markup Testing
Do not use markup assertions for:
- Verifying complex data structures (use database queries instead)
- Complex nested content that's easier to query
- Business logic verification (test behavior, not presentation)
## Database Setup
All tests in `test/clj/auto_ap/` use a shared database fixture (`wrap-setup`) that:
1. Creates a temporary in-memory Datomic database (`datomic:mem://test`)
2. Loads the full schema from `io/resources/schema.edn`
3. Installs custom Datomic functions from `io/resources/functions.edn`
4. Cleans up the database after each test
## Using the Fixture
```clojure
(ns my-test
(:require
[auto-ap.integration.util :refer [wrap-setup]]
[clojure.test :as t]))
(use-fixtures :each wrap-setup)
(deftest my-test
;; tests here can access the test database
)
```
## Helper Functions
`test/clj/auto_ap/integration/util.clj` provides helper functions for creating test data:
### Identity Helpers
```clojure
;; Add a unique string to avoid collisions
(str "CLIENT" (rand-int 100000))
(str "INVOICE " (rand-int 1000000))
```
### Test Entity Builders
```clojure
;; Client
(test-client
[:db/id "client-id"
:client/code "CLIENT123"
:client/locations ["DT" "MH"]
:client/bank-accounts [:bank-account-id]])
;; Vendor
(test-vendor
[:db/id "vendor-id"
:vendor/name "Vendorson"
:vendor/default-account "test-account-id"])
;; Bank Account
(test-bank-account
[:db/id "bank-account-id"
:bank-account/code "TEST-BANK-123"
:bank-account/type :bank-account-type/check])
;; Transaction
(test-transaction
[:db/id "transaction-id"
:transaction/date #inst "2022-01-01"
:transaction/client "test-client-id"
:transaction/bank-account "test-bank-account-id"
:transaction/id (str (java.util.UUID/randomUUID))
:transaction/amount 100.0
:transaction/description-original "original description"])
;; Payment
(test-payment
[:db/id "test-payment-id"
:payment/date #inst "2022-01-01"
:payment/client "test-client-id"
:payment/bank-account "test-bank-account-id"
:payment/type :payment-type/check
:payment/vendor "test-vendor-id"
:payment/amount 100.0])
;; Invoice
(test-invoice
[:db/id "test-invoice-id"
:invoice/date #inst "2022-01-01"
:invoice/client "test-client-id"
:invoice/status :invoice-status/unpaid
:invoice/import-status :import-status/imported
:invoice/total 100.0
:invoice/outstanding-balance 100.00
:invoice/vendor "test-vendor-id"
:invoice/invoice-number "INVOICE 123456"
:invoice/expense-accounts
[{:invoice-expense-account/account "test-account-id"
:invoice-expense-account/amount 100.0
:invoice-expense-account/location "DT"}]])
;; Account
(test-account
[:db/id "account-id"
:account/name "Account"
:account/type :account-type/asset])
```
### Common Data Setup (`setup-test-data`)
Creates a minimal but complete dataset for testing:
```clojure
(defn setup-test-data [data]
(:tempids @(dc/transact conn (into data
[(test-account :db/id "test-account-id")
(test-client :db/id "test-client-id"
:client/bank-accounts [(test-bank-account :db/id "test-bank-account-id")])
(test-vendor :db/id "test-vendor-id")
{:db/id "accounts-payable-id"
:account/name "Accounts Payable"
:db/ident :account/accounts-payable
:account/numeric-code 21000
:account/account-set "default"}]))))
```
Use like:
```clojure
(let [{:strs [test-client-id test-bank-account-id test-vendor-id]} (setup-test-data [])]
...)
```
### Token Helpers
```clojure
;; Admin token
(admin-token)
;; User token (optionally scoped to specific client)
(user-token) ; Default: client-id 1
(user-token client-id) ; Scoped to specific client
```
## Example Usage
```clojure
(ns my-test
(:require
[clojure.test :as t]
[auto-ap.datomic :refer [conn]]
[auto-ap.integration.util :refer [wrap-setup admin-token setup-test-data test-transaction]]))
(use-fixtures :each wrap-setup)
(deftest test-transaction-import
(testing "Should import a transaction"
(let [{:strs [client-id bank-account-id]} (setup-test-data [])
tx-result @(dc/transact conn
[(test-transaction
{:db/id "test-tx-id"
:transaction/client client-id
:transaction/bank-account bank-account-id
:transaction/amount 50.0})])]
(is (= 1 (count (:tx-data tx-result))))
;; Verify by querying the database, not markup
(let [entity (dc/pull (dc/db conn) [:transaction/amount] (:db/id tx-result))]
(is (= 50.0 (:transaction/amount entity)))))))
```
## Note on Temp IDs
Test data often uses string-based temp IDs like `"client-id"`, `"bank-account-id"`, etc. When transacting, the returned `:tempids` map maps these symbolic IDs to Datomic's internal entity IDs:
```clojure
(let [{:strs [client-id bank-account-id]} (:tempids @(dc/transact conn txes))]
...)
```
## Memory Database
All tests use `datomic:mem://test` - an in-memory database. This ensures:
- Tests are fast
- Tests don't interfere with each other
- No setup required to run tests locally
The database is automatically deleted after each test completes.
# running tests
prefer to use clojure nrepl evaluation skill over leiningen, but worst case,
use leiningen to run tests
