+
+## Test Structure
+
+### `events_test.go`
+
+The main test file contains the following test suites:
+
+#### `EventEmissionTestSuite`
+Main test suite that validates:
+
+1. **Real Transaction Event Emissions** (`TestDIDModuleEventEmissions`, `TestDWNModuleEventEmissions`)
+   - Executes actual transactions that trigger events
+   - Verifies events are emitted correctly with proper attributes
+   - Tests each event type individually
+
+2. **Event Persistence and Replay** (`TestEventPersistenceAndReplay`)  
+   - Verifies events persist across multiple queries
+   - Tests event queryability by attributes
+   - Ensures event data consistency over time
+
+3. **Event Querying** (`TestEventQuerying`)
+   - Tests CometBFT query syntax patterns
+   - Validates filtering by event type, creator, and custom attributes
+   - Tests complex query conditions
+
+4. **Multi-Event Transactions** (`TestMultiEventTransactions`)
+   - Tests transactions that emit multiple events
+   - Verifies correct event ordering
+   - Validates block height consistency across events
+
+5. **Event Subscription** (`TestEventSubscription`)
+   - Tests WebSocket-based event subscription via CometBFT
+   - Subscribes to new blocks, transactions, and custom events
+   - Validates real-time event streaming
+
+6. **Event Attribute Validation** (`TestEventAttributeValidation`)
+   - Verifies all required attributes are present
+   - Validates attribute values are correctly populated
+   - Tests attribute consistency
+
+## Client Extensions
+
+### Enhanced StarshipClient (`client/chain.go`)
+
+Extended the existing StarshipClient with comprehensive event querying capabilities:
+
+- `QueryEventsByHeight(height)` - Query events by block height
+- `QueryEventsByType(eventType, minHeight, maxHeight)` - Query by event type
+- `QueryEventsByAttribute(key, value, minHeight, maxHeight)` - Query by attribute
+- `SearchEvents(query, minHeight, maxHeight)` - General CometBFT query search
+- `GetLatestBlockHeight()` - Get current block height
+- `WaitForNextBlock()` - Wait for next block production
+- `FilterEventsByType(events, eventType)` - Filter events by type
+- `GetEventAttribute(event, key)` - Extract specific attribute values
+
+### WebSocket Client (`client/websocket.go`)
+
+New WebSocket client for real-time event subscription:
+
+- `Connect()` - Establish WebSocket connection to CometBFT
+- `Subscribe(query)` - Subscribe to events matching query
+- `SubscribeToNewBlocks()` - Subscribe to new block events
+- `SubscribeToTxEvents()` - Subscribe to transaction events  
+- `SubscribeToDIDEvents()` - Subscribe to DID module events
+- `SubscribeToDWNEvents()` - Subscribe to DWN module events
+- `WaitForEvent(timeout, filter)` - Wait for specific events
+- `WaitForEventByType(timeout, eventType)` - Wait for events by type
+- `Unsubscribe()` - Unsubscribe from events
+
+## Running the Tests
+
+### Prerequisites
+
+1. **Start the Sonr testnet:**
+   ```bash
+   make testnet  # or make start
+   ```
+
+2. **Ensure IPFS is running** (required for DWN tests):
+   ```bash
+   make ipfs-up
+   ```
+
+3. **Verify chain is running:**
+   ```bash
+   curl http://localhost:1317/cosmos/base/tendermint/v1beta1/node_info
+   ```
+
+### Run Event Tests
+
+```bash
+# Run all event tests
+cd test/e2e
+go test -v ./tests/modules/ -run TestEventEmission
+
+# Run specific test suites  
+go test -v ./tests/modules/ -run TestEventEmissionTestSuite/TestDIDModuleEventEmissions
+go test -v ./tests/modules/ -run TestEventEmissionTestSuite/TestEventSubscription
+go test -v ./tests/modules/ -run TestEventEmissionTestSuite/TestEventPersistenceAndReplay
+
+# Run with detailed logging
+go test -v ./tests/modules/ -run TestEventEmission -args -test.v
+```
+
+### Run Integration Tests (for comparison)
+```bash
+# Run the existing integration tests
+cd ../..
+go test -v ./test/ -run TestEventIntegration
+```
+
+## Configuration
+
+### Default Test Configuration (`utils/utils.go`)
+
+- **Chain ID**: `sonrtest_1-1`
+- **Base URL**: `http://localhost:1317` (REST API)
+- **WebSocket URL**: `ws://localhost:26657/websocket` (CometBFT WebSocket)
+- **Staking Denom**: `usnr`
+- **Normal Denom**: `snr`
+
+### Pre-funded Test Accounts
+
+The tests use pre-funded localnet accounts:
+- `idx1fcqk3crpnyvyhtd4jepsnx5eat5ehc920epq29` (Account 0)
+- `idx10n78mn09nx0f056wam35wkfvanf37kepuj28x4` (Account 1)  
+- `idx1xygwjmmj8rq3rq3k4adqvhd55x5yqjc8ktcm7e` (Account 2)
+
+## Implementation Status
+
+### ✅ Completed Features
+
+1. **Event Querying Infrastructure**
+   - REST API event queries
+   - Block height filtering
+   - Attribute-based filtering
+   - CometBFT query syntax support
+
+2. **WebSocket Event Subscription**
+   - Real-time event streaming
+   - Custom query subscriptions
+   - Event filtering and waiting
+
+3. **Test Framework**
+   - Comprehensive test structure
+   - Mock transaction creation
+   - Event validation helpers
+   - Multi-event testing
+
+### 🚧 In Progress / TODO
+
+1. **Real Transaction Building**
+   - Currently using mock transactions for testing
+   - Need to implement actual DID/DWN message building and signing
+   - Integration with existing transaction building utilities
+
+2. **Complete Event Coverage**
+   - Some event tests are marked as "Skip" pending real transaction implementation
+   - Need to create actual transactions for each event type
+
+3. **Chain Restart Testing**
+   - Event persistence across chain restarts
+   - Historical event replay validation
+
+4. **Performance Testing**
+   - Event query performance under load
+   - WebSocket subscription scalability
+   - Large event volume handling
+
+## Key Testing Patterns
+
+### Event Validation Pattern
+```go
+// 1. Execute transaction
+txResp := suite.createTestTransaction(...)
+
+// 2. Wait for inclusion
+finalTx, err := suite.cfg.Client.WaitForTx(ctx, txResp.TxHash, 30*time.Second)
+
+// 3. Filter and validate events
+events := client.FilterEventsByType(finalTx.TxResponse.Events, "EventType")
+require.NotEmpty(t, events, "should emit EventType")
+
+// 4. Validate attributes
+event := events[0]
+value, found := client.GetEventAttribute(event, "key")
+require.True(t, found, "attribute should be present")
+require.Equal(t, expectedValue, value, "attribute value should match")
+```
+
+### WebSocket Subscription Pattern
+```go
+// 1. Connect to WebSocket
+wsClient := client.NewWebSocketClient("ws://localhost:26657")
+err := wsClient.Connect(ctx)
+
+// 2. Subscribe to events
+subscription, err := wsClient.Subscribe(ctx, "custom.query='value'")
+
+// 3. Trigger event (execute transaction)
+txResp := suite.executeTransaction(...)
+
+// 4. Wait for event
+event, err := subscription.WaitForEvent(ctx, 30*time.Second, filterFunc)
+```
+
+### Query Testing Pattern
+```go
+// 1. Record start height
+startHeight, err := suite.cfg.Client.GetLatestBlockHeight(ctx)
+
+// 2. Execute transactions
+// ... create multiple transactions
+
+// 3. Query events with filters
+events, err := suite.cfg.Client.QueryEventsByType(ctx, "EventType", startHeight, 0)
+
+// 4. Validate results
+require.GreaterOrEqual(t, len(events.Events), expectedCount)
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **WebSocket Connection Failed**
+   - Ensure CometBFT is running on port 26657
+   - Check WebSocket endpoint configuration
+   - Verify network connectivity
+
+2. **Event Not Found**
+   - Verify transaction was actually executed
+   - Check event type spelling and case sensitivity
+   - Confirm transaction succeeded (code = 0)
+
+3. **Query Timeout** 
+   - Increase timeout values for slow networks
+   - Check block production is active
+   - Verify query syntax is correct
+
+4. **Missing Events**
+   - Ensure event emission is implemented in keeper
+   - Verify protobuf event definitions match
+   - Check transaction actually triggered the event
+
+### Debug Commands
+
+```bash
+# Check chain status
+curl http://localhost:1317/cosmos/base/tendermint/v1beta1/node_info
+
+# Query latest block
+curl http://localhost:1317/cosmos/base/tendermint/v1beta1/blocks/latest
+
+# Check WebSocket endpoint
+curl -H "Connection: Upgrade" -H "Upgrade: websocket" -H "Sec-WebSocket-Key: test" -H "Sec-WebSocket-Version: 13" http://localhost:26657/websocket
+
+# Query specific transaction
+curl http://localhost:1317/cosmos/tx/v1beta1/txs/{TX_HASH}
+```
+
+## Future Enhancements
+
+1. **Event Analytics Dashboard** - Real-time event monitoring and analytics
+2. **Event Replay Service** - Historical event streaming service  
+3. **Event Benchmarking** - Performance testing for high event volumes
+4. **Cross-Chain Event Testing** - IBC event emission testing
+5. **Event Schema Validation** - Automatic protobuf schema compliance testing
