Add manual test case documentation (20 files + AGENT-TESTING.md)

Comprehensive test case docs covering all 19 MDL command areas:
entity, enumeration, microflow, nanoflow, page, integration,
security, navigation, organization, workflow, catalog, tooling,
CLI commands, SQL, session, mapping, business event, image
collection, and agent/model/KB/MCP.

Each file specifies inputs, expected outputs, and edge cases.
AGENT-TESTING.md provides shared instructions for AI agents
executing these tests.

Validated all 1007 test cases against MDLParser.g4 grammar -
removed 102 hallucinated tests, fixed 16 syntax errors.

+# Business Event Service Test Cases — Manual Testing
+
+**Updated:** 2026-04-29
+**PR:** [mendixlabs/mxcli#301](https://github.com/mendixlabs/mxcli/pull/386)
+
+## Setup
+
+> See [AGENT-TESTING.md](./AGENT-TESTING.md) for build, execution methods, and verification patterns.
+
+---
+
+## 1. SHOW BUSINESS EVENT SERVICES
+
+### 1.1 List all services
+
+```
+show business event services;
+```
+
+**Expected:** Table with columns `Module | QualifiedName | Service | Messages | Publish | Subscribe`. Summary line `(N business event services)`. Sorted alphabetically.
+
+### 1.2 Filter by module
+
+```
+show business event services in MyModule;
+```
+
+**Expected:** Only services from `MyModule`. Same column format.
+
+### 1.3 Empty result
+
+```
+show business event services in NonExistentModule;
+```
+
+**Expected:** `No business event services found.`
+
+---
+
+## 2. SHOW BUSINESS EVENTS
+
+### 2.1 List all business events
+
+```
+show business events;
+```
+
+**Expected:** Table with columns `Service | Message | Operation | Entity | Attributes`. `Operation` values are `PUBLISH` or `SUBSCRIBE`. Summary line `(N business events)`.
+
+### 2.2 Filter by module
+
+```
+show business events in MyModule;
+```
+
+**Expected:** Only events from `MyModule`. Same column format.
+
+### 2.3 Empty module
+
+```
+show business events in NonExistentModule;
+```
+
+**Expected:** Empty result or `No business events found.`
+
+---
+
+## 3. DESCRIBE BUSINESS EVENT SERVICE
+
+### 3.1 Service with publish message
+
+```
+describe business event service MyModule.OrderEvents;
+```
+
+**Expected:** Full MDL output:
+```
+create business event service MyModule.OrderEvents
+  event_name_prefix 'com.example.order'
+  message OrderCreated (
+    OrderId: Long,
+    CustomerName: String,
+    Total: Decimal
+  ) publish entity MyModule.OrderCreatedEvent
+/
+```
+
+### 3.2 Service with subscribe message
+
+```
+describe business event service MyModule.PaymentEvents;
+```
+
+**Expected:** MDL includes `subscribe` keyword with entity and microflow references:
+```
+create business event service MyModule.PaymentEvents
+  event_name_prefix 'com.example.payment'
+  message PaymentReceived (
+    PaymentId: Long,
+    Amount: Decimal,
+    Currency: String
+  ) subscribe entity MyModule.PaymentReceivedEvent microflow MyModule.OnPaymentReceived
+/
+```
+
+### 3.3 Service with multiple messages
+
+```
+describe business event service MyModule.InventoryEvents;
+```
+
+**Expected:** Multiple `message` blocks in output. Each has its own attribute list, operation keyword, and entity reference.
+
+### 3.4 All attribute types
+
+Verify described output includes attributes of each supported type:
+
+| Type | Example |
+|------|---------|
+| Long | `OrderId: Long` |
+| String | `Name: String` |
+| Integer | `Count: Integer` |
+| Boolean | `IsActive: Boolean` |
+| DateTime | `Timestamp: DateTime` |
+| Decimal | `Amount: Decimal` |
+
+### 3.5 Non-existent service
+
+```
+describe business event service MyModule.Fake;
+```
+
+**Expected:** Error — service not found.
+
+---
+
+## 4. DROP BUSINESS EVENT SERVICE
+
+### 5.1 Drop existing service
+
+```
+drop business event service MyModule.OrderEvents;
+```
+
+**Expected:** Service removed. `describe business event service MyModule.OrderEvents` returns error.
+
+### 5.2 Drop non-existent service
+
+```
+drop business event service MyModule.Fake;
+```
+
+**Expected:** Error — service not found.
+
+---
+
+## 5. MULTI-STEP WORKFLOWS
+
+### 5.1 Create entity → create publish service → verify events
+
+```
+create persistent entity MyModule.InvoiceCreatedEvent (
+  InvoiceId: Long,
+  CustomerName: String,
+  TotalAmount: Decimal
+);
+
+create business event service MyModule.InvoiceEvents
+  event_name_prefix 'com.example.invoice'
+  message InvoiceCreated (
+    InvoiceId: Long,
+    CustomerName: String,
+    TotalAmount: Decimal
+  ) publish entity MyModule.InvoiceCreatedEvent;
+
+show business events in MyModule;
+```
+
+**Expected:** All statements succeed. `show business events` lists `InvoiceCreated` with operation `PUBLISH` and entity `MyModule.InvoiceCreatedEvent`.
+
+### 5.2 Create entity → create subscribe service → verify events
+
+```
+create persistent entity MyModule.ShipmentReceivedEvent (
+  ShipmentId: Long,
+  Carrier: String
+);
+
+create business event service MyModule.ShipmentEvents
+  event_name_prefix 'com.example.shipment'
+  message ShipmentReceived (
+    ShipmentId: Long,
+    Carrier: String
+  ) subscribe entity MyModule.ShipmentReceivedEvent microflow MyModule.OnShipmentReceived;
+
+show business events in MyModule;
+```
+
+**Expected:** `show business events` lists `ShipmentReceived` with operation `SUBSCRIBE`.
+
+### 5.3 Create → replace → verify
+
+```
+create business event service MyModule.Lifecycle
+  event_name_prefix 'com.example.lc.v1'
+  message Ping (
+    Seq: Integer
+  ) publish entity MyModule.PingEvent;
+
+create or replace business event service MyModule.Lifecycle
+  event_name_prefix 'com.example.lc.v2'
+  message Ping (
+    Seq: Integer,
+    Timestamp: DateTime
+  ) publish entity MyModule.PingEvent;
+
+describe business event service MyModule.Lifecycle;
+```
+
+**Expected:** Final `describe` shows v2 prefix and `Timestamp` attribute.
+
+---
+
+## 6. FAILURE MODES & ERROR RECOVERY
+
+### 6.1 Not connected to project
+
+```
+show business event services;
+```
+
+(Run without `-p` flag or before opening a project.)
+
+**Expected:** Error — not connected to a project.
+
+### 6.2 Service not found
+
+```
+describe business event service MyModule.DoesNotExist;
+```
+
+**Expected:** Error — service not found.
+
+### 6.3 Service already exists
+
+```
+create business event service MyModule.OrderEvents
+  event_name_prefix 'com.example.order'
+  message Msg (X: Integer) publish entity MyModule.MsgEvent;
+create business event service MyModule.OrderEvents
+  event_name_prefix 'com.example.order'
+  message Msg (X: Integer) publish entity MyModule.MsgEvent;
+```
+
+**Expected:** First succeeds. Second returns error — already exists.
+
+### 6.4 Module not found
+
+```
+show business event services in FakeModule;
+```
+
+**Expected:** `No business event services found.` or error — module not found.
+
+### 6.5 Missing entity reference
+
+```
+create business event service MyModule.BadRef
+  event_name_prefix 'com.example.badref'
+  message Msg (X: Integer) publish entity MyModule.NonExistentEntity;
+```
+
+**Expected:** Error — entity not found.
+
+### 6.6 Invalid attribute type
+
+```
+create business event service MyModule.BadType
+  event_name_prefix 'com.example.badtype'
+  message Msg (X: InvalidType) publish entity MyModule.SomeEvent;
+```
+
+**Expected:** Error — unknown type. No service created.
