## Development Workflow

### Build Commands

```bash
mvn compile                              # Compile
mvn test                                 # Run all tests
mvn test -Dtest=SuggesterTest           # Run specific test
mvn package                              # Package JAR
mvn formatter:format license:format     # Format code and apply licenses

                        .numOfNode(1)
                        .pluginTypes("org.codelibs.opensearch.extension.ExtensionPlugin"));
        runner.ensureYellow();

        suggester = Suggester.builder().build(runner.client(), "SuggesterTest");
    }

    @AfterClass
    public static void afterClass() throws Exception {
        runner.close();
        runner.clean();
    }

    @Test
    public void test_normalize() throws Exception {

    @Before
    public void before() throws Exception {
        runner.admin().indices().prepareDelete("_all").execute().actionGet();
        runner.refresh();
        suggester = Suggester.builder().build(runner.client(), "SuggesterTest");
        suggester.createIndexIfNothing();
    }

    @Test
    public void test_Read() throws Exception {
        String indexName = "test-index";
        Client client = runner.client();

```

### Testing

The project uses JUnit 4 with embedded OpenSearch for integration testing:

```bash
# Run all tests
mvn test

# Run specific test class
mvn test -Dtest=SuggesterTest

# Run with verbose output
mvn surefire:test -Dmaven.surefire.debug=true
```

### Running Tests with Coverage

```bash
mvn clean jacoco:prepare-agent test jacoco:report
```

    }

    /**
     * Integration test for complete index lifecycle with refactored methods.
     * Tests that createNextIndex and switchIndex work together correctly.
     * Note: Full lifecycle testing is covered by SuggesterTest.test_switchIndex()
     */
    @Test
    public void testIndexLifecycle_withRefactoredMethods() throws Exception {
        final Suggester suggester = Suggester.builder().build(client, "lifecycle-test");
