+# Testing Guide for Hommr
+
+## Overview
+
+This project includes a comprehensive test suite with over 2,000 lines of test code covering all major components of the Hommr plugin.
+
+## Quick Start
+
+### Running All Tests
+
+```bash
+./gradlew test
+```
+
+### Running Tests with Detailed Output
+
+```bash
+./gradlew test --info
+```
+
+### Running Specific Test Classes
+
+```bash
+# Run tests for Home model
+./gradlew test --tests HomeTest
+
+# Run tests for PlayerHomes model
+./gradlew test --tests PlayerHomesTest
+
+# Run tests for DatabaseManager
+./gradlew test --tests DatabaseManagerTest
+
+# Run tests for HomeManager
+./gradlew test --tests HomeManagerTest
+
+# Run tests for Hommr plugin class
+./gradlew test --tests HommrTest
+```
+
+### Running Tests for Specific Methods
+
+```bash
+# Run a single test method
+./gradlew test --tests HomeTest.testFromLocationCreatesHomeWithCorrectData
+
+# Run tests matching a pattern
+./gradlew test --tests HomeTest.*Location*
+```
+
+## Test Structure
+
+```
+src/test/java/me/axeno/hommr/
+├── HommrTest.java                    # Main plugin lifecycle tests
+├── managers/
+│   ├── DatabaseManagerTest.java     # Database operations tests
+│   └── HomeManagerTest.java         # Home management logic tests
+└── models/
+    ├── HomeTest.java                 # Home model tests
+    └── PlayerHomesTest.java          # Player homes collection tests
+```
+
+## Test Coverage
+
+- **HomeTest**: 22 tests covering location conversion, data persistence, and edge cases
+- **PlayerHomesTest**: 30 tests covering home collections, thread safety, and case sensitivity
+- **DatabaseManagerTest**: 28 tests covering database operations, persistence, and integrity
+- **HomeManagerTest**: 30+ tests covering business logic, events, and player interactions
+- **HommrTest**: 35+ tests covering plugin lifecycle and component initialization
+
+**Total**: 145+ comprehensive test cases
+
+## Requirements
+
+- **Java**: 21 or higher
+- **Gradle**: 8.x (included via wrapper)
+
+## Test Dependencies
+
+The test suite uses:
+- **JUnit 5** (Jupiter 5.10.1) - Modern testing framework
+- **Mockito 5** (5.8.0) - Mocking framework for dependencies
+- **Paper API** - For Bukkit/Spigot testing
+- **ORMLite** - For database testing
+- **SQLite JDBC** - For in-memory database tests
+
+## Continuous Integration
+
+Tests are automatically run in CI/CD via GitHub Actions on:
+- Pull requests
+- Pushes to main branches
+
+See `.github/workflows/build.yml` for CI configuration.
+
+## Test Patterns
+
+### Mocking Bukkit Objects
+
+```java
+@Mock
+private World mockWorld;
+
+@Mock
+private Player mockPlayer;
+
+@BeforeEach
+void setUp() {
+    when(mockWorld.getName()).thenReturn("world");
+    when(mockPlayer.getUniqueId()).thenReturn(testPlayerId);
+}
+```
+
+### Testing Events
+
+```java
+ArgumentCaptor<HomeSetEvent> eventCaptor = ArgumentCaptor.forClass(HomeSetEvent.class);
+HomeManager.setHome(mockPlayer, "home1", location);
+verify(mockPluginManager).callEvent(eventCaptor.capture());
+HomeSetEvent event = eventCaptor.getValue();
+assertEquals("home1", event.getHomeName());
+```
+
+### Testing Database Operations
+
+```java
+@TempDir
+Path tempDir;
+
+@BeforeEach
+void setUp() {
+    when(mockPlugin.getDataFolder()).thenReturn(tempDir.toFile());
+    databaseManager.init();
+}
+```
+
+## Writing New Tests
+
+### Best Practices
+
+1. **Test Naming**: Use descriptive names that explain what is being tested
+   - ✅ `testSetHomeCreatesNewHome()`
+   - ❌ `testSetHome1()`
+
+2. **Arrange-Act-Assert**: Structure tests clearly
+   ```java
+   @Test
+   void testSetHomeCreatesNewHome() {
+       // Arrange
+       Location location = new Location(mockWorld, 100, 64, 200);
+
+       // Act
+       boolean result = HomeManager.setHome(mockPlayer, "home1", location);
+
+       // Assert
+       assertTrue(result);
+       assertTrue(HomeManager.hasHome(testPlayerId, "home1"));
+   }
+   ```
+
+3. **Test Isolation**: Each test should be independent
+   - Use `@BeforeEach` for setup
+   - Use `@AfterEach` for cleanup
+   - Don't rely on test execution order
+
+4. **Edge Cases**: Always test boundary conditions
+   - Null values
+   - Empty collections
+   - Maximum/minimum values
+   - Special characters
+
+5. **Mock Cleanup**: Close static mocks in `@AfterEach`
+   ```java
+   @AfterEach
+   void tearDown() {
+       if (bukkitMockedStatic != null) {
+           bukkitMockedStatic.close();
+       }
+   }
+   ```
+
+## Debugging Tests
+
+### Enable Debug Logging
+
+```bash
+./gradlew test --debug
+```
+
+### Show Standard Output
+
+Edit `build.gradle`:
+```gradle
+test {
+    testLogging {
+        showStandardStreams = true
+    }
+}
+```
+
+### Run Tests in IDE
+
+Most IDEs (IntelliJ IDEA, Eclipse, VS Code) can run JUnit 5 tests directly:
+1. Right-click on test class or method
+2. Select "Run Test" or "Debug Test"
+
+## Common Issues
+
+### Test Failures
+
+1. **Mockito Issues**: Ensure all mocks are properly initialized with `@ExtendWith(MockitoExtension.class)`
+2. **Static Mocks**: Always close `MockedStatic` instances in `@AfterEach`
+3. **Bukkit API**: Use mocks for all Bukkit classes (Server, World, Player, etc.)
+
+### Build Issues
+
+1. **Java Version**: Ensure Java 21 is installed
+   ```bash
+   java -version
+   ```
+
+2. **Gradle Sync**: Refresh Gradle dependencies
+   ```bash
+   ./gradlew --refresh-dependencies
+   ```
+
+## Performance
+
+Tests are designed to run quickly:
+- **Unit Tests**: < 1 second per test
+- **Database Tests**: Use in-memory SQLite for speed
+- **Full Suite**: Typically completes in < 30 seconds
+
+## Coverage Reports
+
+To generate code coverage reports (requires JaCoCo plugin):
+
+```bash
+./gradlew test jacocoTestReport
+```
+
+Report will be available at: `build/reports/jacoco/test/html/index.html`
+
+## Contributing Tests
+
+When adding new features:
+1. Write tests first (TDD approach) or alongside the implementation
+2. Ensure at least 80% code coverage for new code
+3. Include both positive and negative test cases
+4. Test edge cases and boundary conditions
+5. Update this documentation if adding new test patterns
