DB Tester Limitations

Data Format Limitations

Limitation	Impact	Workaround
No YAML/JSON support	Cannot use human-friendly formats for complex nested data	Use CSV with clear column naming
No XML support	Cannot migrate from existing DBUnit XML datasets	Convert XML to CSV manually or via script
No Excel support	Business users cannot maintain test data in spreadsheets	Export Excel to CSV
No programmatic dataset builder	Cannot generate dynamic test data in code	Implement custom DataLoader via SPI

Feature Limitations

Limitation	Impact	Alternative
No delta assertions	Cannot verify only the changes made by test	Verify full expected state

| No scriptable datasets | Cannot embed dynamic values in CSV | Prepare data programmatically before each test | | No dataset export | Cannot capture current DB state for debugging | Use database client tools | | No replacement/placeholder | Cannot use variables in datasets | Define explicit values per scenario | | No sequence reset | Cannot reset auto-increment counters | Handle via SQL in @BeforeEach | | No connection leak detection | Connection leaks may go unnoticed | Use external monitoring tools |

Ecosystem Limitations

Limitation	Impact	Consideration
No JUnit 4/5 support	Cannot use with legacy test suites	Migrate to JUnit 6 or use Database Rider
No TestNG support	Limited options for TestNG users	Use DbSetup or JDBDT
No CDI integration	Cannot auto-inject in Jakarta EE	Register DataSource manually
No Cucumber support	Cannot use in BDD scenarios	Use Database Rider for BDD
New project	Smaller community, less battle-tested	Evaluate thoroughly before production use
Limited documentation	Fewer examples and tutorials	Refer to test cases in source code

When NOT to Choose DB Tester

Consider alternatives if you need:

1. Multiple data formats → Choose Database Rider
2. Existing XML datasets → Choose DBUnit or Database Rider
3. BDD/Cucumber integration → Choose Database Rider
4. JUnit 4/5 or TestNG → Choose DBUnit, Database Rider, or DbSetup
5. Delta assertions → Choose JDBDT
6. Code-only approach → Choose DbSetup
7. Mature, battle-tested solution → Choose DBUnit

Framework Deep Dive

DB Tester

Philosophy: Convention over configuration with minimal boilerplate.

Unique Strengths:

• Zero-configuration dataset discovery based on test class and method names
• Scenario filtering shares datasets across multiple test methods
• YAML-formatted assertion errors provide readable debugging output
• Native Kotest support (only framework with this feature)
• SPI enables custom extensions

Architecture:

db-tester-api     → Public annotations and interfaces
db-tester-core    → JDBC implementation (internal)
db-tester-junit   → JUnit 6 extension
db-tester-spock   → Spock 2 extension
db-tester-kotest  → Kotest 6 extension

Example:

@ExtendWith(DatabaseTestExtension.class)
@DataSet  // Loads com/example/UserTest/users.csv
@ExpectedDataSet  // Verifies against com/example/UserTest/expected/users.csv
class UserTest {
    @Test
    void shouldCreateUser() {
        // [Scenario] column filters rows for this method
        repository.create(new User("john", "john@example.com"));
    }
}

DBUnit

Philosophy: Comprehensive database state management with extensive customization options.

Unique Strengths:

• Most mature and battle-tested framework (since 2002)
• Extensive XML dataset support with schema validation
• ReplacementDataSet supports dynamic placeholders
• Database export captures production-like data
• Wide IDE and tool integration

Core Components:

• IDatabaseConnection - Database connection abstraction
• IDataSet - Collection of tables (FlatXml, Xml, Xls, Query, and others)
• DatabaseOperation - CRUD operations on datasets

Example:

@Before
public void setUp() throws Exception {
    IDatabaseConnection connection = new DatabaseConnection(dataSource.getConnection());
    IDataSet dataSet = new FlatXmlDataSetBuilder().build(new File("dataset.xml"));
    DatabaseOperation.CLEAN_INSERT.execute(connection, dataSet);
}

Database Rider

Philosophy: Comprehensive DBUnit wrapper with annotation-driven API.

Unique Strengths:

• Widest data format support (YAML, JSON, XML, CSV, Excel)
• Scriptable datasets use Groovy/JavaScript
• Regex matching in expected datasets
• CDI and Cucumber integration
• Connection leak detection
• Active development and active community

Configuration Options:

@DataSet(
    value = "users.yml",
    strategy = SeedStrategy.CLEAN_INSERT,
    cleanBefore = true,
    cleanAfter = true,
    disableConstraints = true,
    transactional = true,
    executeStatementsBefore = "SET FOREIGN_KEY_CHECKS=0",
    executeStatementsAfter = "SET FOREIGN_KEY_CHECKS=1"
)

Example:

@ExtendWith(DBUnitExtension.class)
class UserTest {
    @Test
    @DataSet("users.yml")
    @ExpectedDataSet(value = "expected.yml", ignoreCols = {"id", "created_at"})
    void shouldUpdateUser() {
        repository.update(1L, new User("john.doe"));
    }
}

Spring Test DBUnit

Philosophy: Seamless Spring integration for DBUnit.

Unique Strengths:

• Deep Spring TestContext integration
• Transaction management integrates with Spring
• Familiar annotation style for Spring developers
• TestExecutionListener-based approach

Limitations:

• No active maintenance (last release 2016)
• No JUnit 5 support
• Spring-only

Example:

@RunWith(SpringJUnit4ClassRunner.class)
@TestExecutionListeners({
    DependencyInjectionTestExecutionListener.class,
    TransactionDbUnitTestExecutionListener.class
})
@DatabaseSetup("/initial-data.xml")
@ExpectedDatabase("/expected-data.xml")
public class UserRepositoryTest {
    @Test
    public void shouldUpdateUser() { ... }
}

DbSetup

Philosophy: Pure code, no external files, fast execution.

Unique Strengths:

• Zero external dependencies
• Type-safe Java/Kotlin DSL
• DbSetupTracker optimizes test execution
• Value generators handle sequences
• Fast execution

Limitations:

• Setup only, no assertion capabilities
• No annotation support
• Requires more boilerplate code

Example:

private static final Operation DELETE_ALL = deleteAllFrom("users", "orders");
private static final Operation INSERT_REFERENCE_DATA = sequenceOf(
    insertInto("users")
        .columns("id", "name", "email")
        .values(1L, "john", "john@example.com")
        .values(2L, "jane", "jane@example.com")
        .build()
);

@BeforeEach
void prepare() {
    new DbSetup(destination, sequenceOf(DELETE_ALL, INSERT_REFERENCE_DATA)).launch();
}

Kotlin DSL:

val operation = dbSetup(to = destination) {
    deleteAllFrom("users")
    insertInto("users") {
        columns("id", "name", "email")
        values(1L, "john", "john@example.com")
    }
}
operation.launch()

JDBDT

Philosophy: Lightweight delta testing without external dependencies.

Unique Strengths:

• Delta assertions verify only changes
• Self-contained (Java 8 SE only)
• Programmatic dataset builders
• CSV import/export support
• Lightweight (~100KB)

Delta Assertion Concept:

Initial State (Snapshot) → Test Execution → Final State
                                ↓
                          δ = Final - Initial
                                ↓
                    Assert: δ matches expected changes

Example:

@Before
public void setup() {
    // Take snapshot of initial state
    snapshot = takeSnapshot(userTable);
}

@Test
public void testInsertUser() {
    // Execute code under test
    repository.insert(new User("john"));

    // Assert only the delta (inserted rows)
    assertInserted(
        data(userTable)
            .row("john", "john@example.com")
    );
}

@Test
public void testQueryDoesNotModify() {
    repository.findAll();

    // Assert no changes were made
    assertUnchanged(userTable);
}
