+
+## Running Tests
+
+### Prerequisites
+
+1. **Start MCP Server**:
+   ```bash
+   cd moqui-mcp-2
+   ../gradlew run --daemon > ../server.log 2>&1 &
+   ```
+
+2. **Verify Server is Running**:
+   ```bash
+   curl -s -u "john.sales:opencode" "http://localhost:8080/mcp"
+   ```
+
+### Run All Tests
+
+```bash
+cd moqui-mcp-2
+./test/run-tests.sh
+```
+
+### Run Individual Tests
+
+#### General MCP Test Client
+```bash
+cd moqui-mcp-2
+groovy -cp "lib/*:build/libs/*:../framework/build/libs/*:../runtime/lib/*" \
+    test/client/McpTestClient.groovy
+```
+
+#### E-commerce Workflow Test
+```bash
+cd moqui-mcp-2
+groovy -cp "lib/*:build/libs/*:../framework/build/libs/*:../runtime/lib/*" \
+    test/workflows/EcommerceWorkflowTest.groovy
+```
+
+## Test Workflows
+
+### 1. Basic MCP Test Client (`McpTestClient.groovy`)
+
+Tests core MCP functionality:
+- ✅ Session initialization and management
+- ✅ Tool discovery and execution
+- ✅ Resource access and querying
+- ✅ Error handling and validation
+
+**Workflows**:
+- Product Discovery Workflow
+- Order Placement Workflow
+- E-commerce Full Workflow
+
+### 2. E-commerce Workflow Test (`EcommerceWorkflowTest.groovy`)
+
+Tests complete business workflow:
+- ✅ Product Discovery
+- ✅ Customer Management
+- ✅ Order Placement
+- ✅ Screen-based Operations
+- ✅ Complete Workflow Execution
+- ✅ Test Data Cleanup
+
+## Test Data Management
+
+### Automatic Cleanup
+Test data is automatically created and cleaned up during tests:
+- Products: Prefix `TEST-`
+- Customers: Prefix `TEST-`
+- Orders: Prefix `TEST-ORD-`
+
+### Manual Cleanup
+```bash
+# Using mcp.sh
+./mcp.sh call org.moqui.mcp.McpTestServices.cleanup#TestData olderThanHours=24
+
+# Direct service call
+curl -u "john.sales:opencode" -X POST \
+  "http://localhost:8080/rest/s1/org/moqui/mcp/McpTestServices/cleanup#TestData" \
+  -H "Content-Type: application/json" \
+  -d '{"olderThanHours": 24}'
+```
+

+
+## Troubleshooting
+
+### Common Issues
+
+#### 1. MCP Server Not Running
+```
+❌ MCP server is not running at http://localhost:8080/mcp
+```
+**Solution**: Start the server first
+```bash
+cd moqui-mcp-2 && ../gradlew run --daemon > ../server.log 2>&1 &
+```
+
+#### 2. Authentication Failures
+```
+❌ Error: Authentication required
+```
+**Solution**: Verify credentials in `opencode.json` or use default `john.sales:opencode`
+
+#### 3. Missing Test Services
+```
+❌ Error: Service not found: org.moqui.mcp.McpTestServices.create#TestProduct
+```
+**Solution**: Rebuild the project
+```bash
+cd moqui-mcp-2 && ../gradlew build
+```
+
+#### 4. Classpath Issues
+```
+❌ Error: Could not find class McpTestClient
+```
+**Solution**: Ensure proper classpath
+```bash
+groovy -cp "lib/*:build/libs/*:../framework/build/libs/*:../runtime/lib/*" ...
+```
+
+### Debug Mode
+
+Enable verbose output in tests:
+```bash
+# For mcp.sh
+./mcp.sh --verbose ping
+
+# For Groovy tests
+# Add debug prints in the test code
+```
+
+### Log Analysis
+
+Check server logs for detailed error information:
+```bash
+tail -f ../server.log
+tail -f ../moqui.log
+```
+
+## Extending Tests
+
+### Adding New Test Services
+
+1. Create service in `../service/McpTestServices.xml`
+2. Rebuild: `../gradlew build`
+3. Add test method in appropriate test client
+4. Update documentation
+
+### Adding New Workflows
+
+1. Create new test class in `test/workflows/`
+2. Extend base test functionality
+3. Add to test runner if needed
+4. Update documentation
+
+## Performance Testing
+
+### Load Testing
+```bash
+# Run multiple concurrent tests
+for i in {1..10}; do
+    groovy test/workflows/EcommerceWorkflowTest.groovy &
+done
+wait
+```
+
+### Benchmarking
+Tests track execution time and can be used for performance benchmarking.
+
+## Security Testing
+
+The test suite validates:
+- ✅ Authentication requirements
+- ✅ Authorization enforcement
+- ✅ Session isolation
+- ✅ Permission-based access control
+
+## Integration with CI/CD
+
+### GitHub Actions Example
+```yaml
+- name: Run MCP Tests
+  run: |
+    cd moqui-mcp-2
+    ./test/run-tests.sh
+```
+
+### Jenkins Pipeline
+```groovy
+stage('MCP Tests') {
+    steps {
+        sh 'cd moqui-mcp-2 && ./test/run-tests.sh'
+    }
+}
+```
+
+## Contributing
+
+When adding new tests:
+1. Follow existing naming conventions
+2. Include proper error handling
+3. Add comprehensive logging
+4. Update documentation
+5. Test with different data scenarios
+
+## Support
+
+For test-related issues:
+1. Check server logs
+2. Verify MCP server status
+3. Validate test data
+4. Review authentication setup
+5. Check network connectivity
+
+---
+
+**Note**: These tests are designed for development and testing environments. Use appropriate test data and cleanup procedures in production environments.
