Summary

  • Add org.dbunit.annotation, a JUnit-free annotation vocabulary for declarative dbUnit
    test configuration: @DbUnitPrep/@DbUnitSetup for setup, @DbUnitExpected/
    @DbUnitVerifyTable/@DbUnitColumnComparer for prep/expected verification,
    @DbUnitTearDown for cleanup, @DbUnitConfig for loader/tester/properties/catalog
    wiring, @DbUnitProperty for DatabaseConfig properties, @DbUnitTester/
    @DbUnitTestCase field markers, @DbUnitRowCountCheck fronting the row count check
    (Add an opt-in row count check that detects tables missed by, or wrongly included in, test teardown #939), and the DataSetPathsProvider/DatabaseConfigPropertiesProvider/
    VerifyTableDefinitionsProvider SPIs for sharing values an annotation cannot
    reference directly (JLS 9.7.1). Layered under org.dbunit.annotation.runtime, the
    JUnit-free machinery that resolves and drives the annotations, so a future
    non-Jupiter binding (Add Spring TestExecutionListener integration #754) can reuse the same vocabulary.
  • Rewrite DbUnitExtension (JUnit 5/6) to run on this vocabulary instead of the
    package-private DbUnitSetup/DbUnitTeardown/DbUnitOperation/
    DataSetResourceLoader it shipped with in 3.5.0 - never released with that shape
    publicized, so free to replace. Adds the prep/expected path driving a
    PrepAndExpectedTestCase, @DbUnitConfig-driven tester/test-case resolution, a
    ParameterResolver for IDatabaseTester/PrepAndExpectedTestCase/
    IDatabaseConnection/Connection, @Nested test class support, and @DbUnitTest
    as a one-line opt-in.
  • Add JsonDataFileLoader, YamlDataFileLoader, and FileExtensionDataFileLoader
    (dispatching by file extension) to org.dbunit.util.fileloader, filling a gap where
    JSON and YAML datasets had no matching loader - now the default @DbUnitConfig
    loader.
  • New site page testcases/annotations.adoc, plus edits across components.adoc,
    fiveminutes.adoc, howto.adoc, testcases.adoc, and the individual component
    pages linking to it.

Test plan

  • ./mvnw clean test - 2246 unit tests, 0 failures/errors
  • ./mvnw clean verify -Phsqldb-2-7 / -Ph2-1-4 - 371 IT tests each, 0 failures/errors
  • ./mvnw clean install site - checkstyle, Javadoc/doclint, and site rendering all clean
  • All-database CI matrix (build-any-branch-with-all-dbs.yml) green across all ten
    profiles: derby, h2, hsqldb, mariadb, mssql, mysql, oracle-18, oracle-23,
    postgresql, db2
  • Manual read-through of the rendered testcases/annotations.adoc - every code
    sample checked against the final API

Summary by Sourcery

Add an annotation-driven configuration layer and supporting runtime for dbUnit tests, refactor the JUnit Jupiter DbUnitExtension to consume it (including prep/expected and row-count-check support), and extend dataset loading and documentation to cover JSON/YAML and the new annotation-based flows.

New Features:

  • Introduce a JUnit-independent org.dbunit.annotation vocabulary for declarative test configuration, including setup, expected verification, teardown, config, properties, tester/test-case markers, and row count check wiring.
  • Add JSON and YAML dataset file loaders plus a file-extension-based DataFileLoader dispatcher, and make them consumable from annotation-driven configuration.

Bug Fixes:

  • Ensure DbUnitExtension correctly applies setup and teardown in both simple and prep/expected paths, and fixes previous gaps around teardown on the prep/expected path.

Enhancements:

  • Refactor DbUnitExtension to drive tests via the new annotation runtime layer, adding support for prep/expected verification, tester/test-case resolution strategies, parameter injection, nested test classes, and the DbUnitTest composed annotation.
  • Add runtime support classes for resolving annotation-based configurations and executing tests, including dataset path resolution, verify-table catalogs, and row count check integration with annotation overrides.

Documentation:

  • Extend the Maven site with a new DbUnit Annotations testcases page and cross-links from existing lifecycle, components, datasets, and how-to documentation, and update the release notes to describe the new annotation-based configuration and loaders.

Tests:

  • Expand unit, integration, and engine-testkit coverage for DbUnitExtension’s new annotation-driven lifecycle, row count check behavior, parameter resolution, dataset loading by extension, and annotation runtime utilities, including real-database ITs verifying configuration and cleanup semantics.

Chores:

  • Update licensing years and contributor tooling guidance, including Conventional Commit scopes for annotations and JUnit-related changes.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟡 Moderate · up to c0dde

The annotation-driven lifecycle can reuse mutable database testers across tests, allowing setup state or callbacks to leak between executions; parameter injection may also provide null in a supported case, and the published tester interface may break external implementations. These bounded correctness and compatibility risks require explicit owner acceptance or fixes before merge.

Hey - I've found 1 issue, and left some high level feedback:

  • DbUnitExtension has grown quite large with mixed responsibilities (annotation discovery, tester/test-case resolution, parameter injection); consider extracting some of the resolution helpers (e.g., field discovery and configuration lookup) into dedicated classes to keep the extension focused and easier to maintain.
  • The reflective construction helpers (e.g., newInstance/instantiate patterns in DbUnitExtension, AnnotatedTestConfiguration, AnnotatedTestExecutor, VerifyTableDefinitionCatalog) are very similar; centralizing these into a shared utility would reduce duplication and make error handling more consistent.

**issue (bug_risk):** Parameter resolution recomputes tester/test-case independently of the executor, which can lead to duplicated or inconsistent instances.

`resolveParameter()` invokes `resolveConfiguration()` and `resolve()` for each parameter instead of reusing the `AnnotatedTestExecutor` stored in the `ExtensionContext` during `beforeTestExecution()`. This can create new `PrepAndExpectedTestCase` or `IDatabaseTester` instances that differ from those controlling the test lifecycle, causing inconsistent configuration, duplicated setup, and extra overhead. Please resolve parameters by retrieving the existing `AnnotatedTestExecutor` from the store and using its tester/testCase and connection so lifecycle and parameter injection use the same instances.

and true in the other enabled tests, and rename the helper if needed to reflect
that it supports both states while avoiding unnecessary Mockito stubs.

In
`@src/test/java/org/dbunit/annotation/runtime/DataSetResourcePathResolverTest.java`:
- Around line 49-57: Rename the test fixture class Nested to NestedTestClass and
update its reference in testResolve_nestedTestClass_prefixesEnclosingPackage,
preserving the existing package-prefix resolution assertion.

In `@src/test/java/org/dbunit/junit/jupiter/DbUnitExtensionLifecycleTest.java`:
- Around line 132-143: Reset the ExpectedPathSample fixture before executing the
engine by assigning a fresh RecordingPrepAndExpectedTestCase, matching the setup
in the other lifecycle tests so postTestCalls starts empty. Also remove the
initializer from ExpectedPathSample.testCase and declare it without an initial
value.

In
`@src/test/java/org/dbunit/junit/jupiter/DbUnitExtensionRowCountCheckLifecycleTest.java`:
- Around line 146-156: Replace the local ConnectionSupplier interface in
FixedConnectionTester with java.util.function.Supplier<IDatabaseConnection>,
updating the field, constructor parameter, and invocation sites while preserving
the existing fixed-connection behavior.
- Around line 70-83: Update
testAfterTestExecution_rowCountCheckAndFailingTest_skipsCheckAndReportsOriginalFailure
to assert the executed test’s reported throwable, following the existing pattern
from the first test in the class, instead of validating
FailingTestSample.connection.getRowCount("ACCOUNT"). Ensure the assertion
verifies the original test failure is reported and does not rely on the stubbed
row-count value.

In `@src/test/java/org/dbunit/junit/jupiter/DbUnitExtensionTest.java`:
- Around line 137-147: Rename the test method to follow the
test<MethodName>_<StartingStateConditions>_<AssertedOutcome> convention, using
supportsParameter and describing that an unsupported parameter type is not
claimed; do not change the test body or behavior.
- Around line 123-133: The afterTestExecution suppression path is untested. In
DbUnitExtensionTest, add a test alongside
testAfterTestExecution_noStoredExecutor_doesNothing that stores an executor
whose afterTest throws, configures context.getExecutionException() with the
original failure, invokes extension.afterTestExecution(context), and asserts the
original throwable contains the after-test exception as suppressed.
- Around line 245-261: Reset the mutable static fixtures
HasStaticMarkedTester.tester and RecordingFactory.next after each test, using an
`@AfterEach` method so test state cannot leak or interfere across executions.
- Around line 164-190: Add resolveParameter tests in DbUnitExtensionTest for
PrepAndExpectedTestCase, IDatabaseConnection, and Connection, covering
successful resolution with the appropriate configured test instance or field and
the missing `@DbUnitTestCase` case returning the expected failure rather than
null. Reuse the existing ParameterHost, givenTestInstance, and assertion
patterns, while preserving the existing IDatabaseTester tests.

Addressing CodeRabbit's 15 collapsed nitpick comments and Sourcery's general "Reviewer's Guide" comment together, since neither is individually reply-able (nitpicks are bundled in the review body rather than posted as separate line comments, and the Sourcery guide is a top-level issue comment, not a review comment). The 13 line-anchored comments (12 CodeRabbit actionable + 1 Sourcery) each got their own inline reply.

Nitpicks — fixed:

  • AnnotatedTestConfiguration.java: getDatabaseConfigProperties() now returns a defensive copy instead of the provider's shared Properties instance; getPrepDataFiles(), getExpectedDataFiles(), getVerifyTableDefinitions(), and getRowCountCheckExclude() now .clone() their backing arrays before returning, so a caller can't mutate this class's internal state through the getter.
  • DbUnitExtensionTest.java: renamed testResolveParameter_unsupportedType_neverInvoked_supportsParameterFalse to testSupportsParameter_unsupportedType_returnsFalse; added testAfterTestExecution_afterTestThrowsAfterTestMethodAlreadyFailed_attachesAsSuppressed covering the previously-untested suppression branch; added an @AfterEach resetting the static fixture fields two other tests were relying on being reset between runs.
  • DbUnitExtensionParameterResolverTest.java: added 4 EngineTestKit-based tests proving factory-invoked-once, @BeforeEach/@Test both receiving the same injected test case, a clear failure when injecting PrepAndExpectedTestCase without a @DbUnitTestCase field, and both connection parameter types receiving the tester's connection.
  • DbUnitExtension.java: swapped the deprecated AnnotationSupport.findAnnotation(Class, Class, SearchOption) overload for findAnnotation(Class, Class, List<Class<?>>) fed by context.getEnclosingTestClasses().
  • DataSetResourcePathResolverTest.java: renamed the Nested fixture to NestedTestClass to avoid colliding with JUnit's own @Nested in reader's eyes.
  • DbUnitOperation.java: refactored from a switch-based toDatabaseOperation() to enum-constructor-arg mapping (favors immutability/constructor-injection per this repo's own style guide).
  • VerifyTableDefinitionCatalog.java: readConstants() now sorts Class.getFields() by name before reading, since reflection's field order is unspecified; added a regression test with out-of-order-declared constants.
  • AnnotatedTestExecutorTest.java: refactored stubEnabledConnection() into stubConnection(boolean, String...) + a stubEnabledConnection that delegates with true, so the 3 precedence tests state their base FEATURE_ROW_COUNT_CHECK value explicitly instead of stubbing true then immediately re-stubbing false.
  • DbUnitExtensionRowCountCheckLifecycleTest.java: replaced the local ConnectionSupplier interface with java.util.function.Supplier<IDatabaseConnection>; fixed testAfterTestExecution_rowCountCheckAndFailingTest_skipsCheckAndReportsOriginalFailure to assert the actual reported Throwable from the failed-event payload instead of a stub value that would have passed even if the skip logic were broken.
  • DbUnitExtensionLifecycleTest.java: ExpectedPathSample.testCase is no longer initialized once at class-load; the test method now assigns a fresh instance at the top, matching the pattern the other sample fixtures already used.

Nitpicks — declined:

  • The suggestion to extract the near-identical 4-line reflective newInstance/instantiate helper duplicated across DbUnitExtension, AnnotatedTestConfiguration, and VerifyTableDefinitionCatalog into a shared utility. Per this repo's CLAUDE.md ("don't add abstractions beyond what the task requires," "three similar lines is better than a premature abstraction," and "do not create utils or helper packages/classes"), leaving these as three small private methods is the better fit here. Reasonable as a follow-up if a fourth call site shows up.
  • The docstring-coverage warning: not applicable — this project documents with Javadoc (already required and present on every public class/method per CLAUDE.md), not docstrings.

Sourcery's general "Reviewer's Guide" comment:

Its architecture note — that DbUnitExtension has grown large with mixed responsibilities (field/annotation resolution, parameter injection, lifecycle callbacks) — is a fair observation, but for the same reason as the helper-duplication nitpick above: it's a legitimate follow-up for a deliberate, separately-reviewed refactor PR, not something to fold into this one opportunistically.

151-160: 🚀 Performance & Scalability | 🔵 Trivial | 💤 Low value

Guard against nesting one listener wrapper per test on a shared tester.

installPropertyListenerIfNeeded() runs in the constructor, and one AnnotatedTestExecutor is created per test. When a fixture holds the tester in a static field and the class has several test methods, each new executor wraps the previously installed PropertyApplyingOperationListener again. The wrapper chain grows by one layer per test and is never removed. Behavior stays correct, but property application repeats once per layer.

Several fixtures in this PR use a shared static tester, for example PropertySample.databaseTester in src/test/java/org/dbunit/junit/jupiter/DbUnitConfigPropertiesIT.java.

♻️ Proposed guard
 private void installPropertyListenerIfNeeded() {
     final Properties properties = configuration.getDatabaseConfigProperties();
     if (!properties.isEmpty()) {
         final IOperationListener existingListener = tester.getOperationListener();
+        if (existingListener instanceof PropertyApplyingOperationListener) {
+            // already wrapped by a previous test sharing this tester; re-wrap its
+            // delegate instead of stacking another layer.
+            tester.setOperationListener(new PropertyApplyingOperationListener(properties,
+                    ((PropertyApplyingOperationListener) existingListener).delegate));
+            return;
+        }
         final IOperationListener delegate =
                 existingListener != null ? existingListener : new DefaultOperationListener();
         tester.setOperationListener(
                 new PropertyApplyingOperationListener(properties, delegate));
     }

Reset the static recorder fields between tests.

instance, lastTester, and lastCloseConnectionAfterTest are static and never cleared. Only testBeforeTest_expectedPathWithoutInjectedTestCase_constructsConfiguredClass reads them today, so the tests pass. When a second test constructs this fixture, stale values can satisfy assertions that should fail.

Add a @BeforeEach that clears the three fields, or move the recording into an instance field the test owns.

1628-1630: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Copy the configured properties before storing them.

setDatabaseConfigProperties retains the caller-owned Properties instance. A later caller mutation changes the database configuration that this test case applies. Copy the entries before assignment. Add a regression assertion that mutates properties after this call and still observes the original configured value.

As per coding guidelines, “Favor immutability. Try to not need setters.”

Proposed change
 public void setDatabaseConfigProperties(final Properties databaseConfigProperties)
 {
-    this.databaseConfigProperties = databaseConfigProperties;
+    if (databaseConfigProperties != null)
+    {
+        final Properties copy = new Properties();
+        copy.putAll(databaseConfigProperties);

40-46: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Initialize the loader field directly and drop setUp().

FileExtensionDataFileLoader needs no per-test state reset except a fresh instance. A final field with an inline initializer gives each test instance its own loader and removes the lifecycle method. This also matches the guideline preference for immutability.

♻️ Proposed change
-    FileExtensionDataFileLoader loader = null;
-
-    `@BeforeEach`
-    protected void setUp() throws Exception
-    {
-        loader = new FileExtensionDataFileLoader();
-    }
+    private final FileExtensionDataFileLoader loader = new FileExtensionDataFileLoader();

Remove the now-unused import:

-import org.junit.jupiter.api.BeforeEach;

Consider enforcing the "every constant" claim.

Consider restoring the tester's original listener after the test.

installOperationListener() replaces the tester's listener in the constructor. Nothing restores it. For a static tester field shared across a class, the ExecutorOperationListener from the last test stays installed after the class finishes. It captures this::peekResolvedConnection, so the last executor and its memoized IDatabaseConnection stay reachable for the lifetime of that static field.

unwrapExistingDelegate() already prevents wrapper nesting, so this is retention only, not growth. Restoring the delegate at the end of afterTest(boolean) would remove the retention.

Wrap the remaining reflective failures from newPrepAndExpectedTestCase().

constructor.newInstance(...) also throws InstantiationException and IllegalAccessException. The catch block handles only InvocationTargetException. Both other failures propagate raw through beforeTest(), so an abstract or otherwise non-instantiable prepAndExpectedTestCase class produces a bare reflective exception without the class name or the attribute name. The NoSuchMethodException branch at Line 389 and instantiateComparer in AnnotatedTestConfiguration already wrap their failures.

- Around line 166-170: Correct the scope statement in the step 4 JUnit 5/6
example: do not claim only the test method changes, since the example also adds
DbUnitTest and DbUnitTester configuration and replaces programmatic teardown
with DbUnitTearDown. State instead that createSchema() and the DRIVER_CLASS,
CONNECTION_URL, ACCOUNT_PREP, and ACCOUNT_EXPECTED constants remain unchanged.

Add JsonDataFileLoader and YamlDataFileLoader to
org.dbunit.util.fileloader, filling the gap where the JSON and YAML
dataset formats had no matching DataFileLoader.

Add FileExtensionDataFileLoader, which dispatches to the right loader -
flat XML, JSON, YAML, or Excel - by a data file's extension, sharing its
delegate loaders as immutable statics. Note on XlsDataFileLoader that it
also loads .xlsx.

Add org.dbunit.annotation, a JUnit-free vocabulary for declarative
DbUnit test configuration:
* @DbUnitPrep and @DbUnitSetup for setup
* @DbUnitExpected, @DbUnitVerifyTable, and @DbUnitColumnComparer for
  prep/expected verification
* @DbUnitTearDown for cleanup
* @DbUnitConfig for loader, tester, properties, and catalog wiring
* @DbUnitProperty for DatabaseConfig properties
* @DbUnitRowCountCheck as the front end for the row count check (issue
  939)
* @DbUnitTester and @DbUnitTestCase field markers

Add org.dbunit.operation.DbUnitOperation mirroring DatabaseOperation's
constants for the operation attributes and three value-sharing SPIs,
each in the package of what it supplies:
* DataSetPathsProvider
* DatabaseConfigPropertiesProvider
* VerifyTableDefinitionsProvider

Add org.dbunit.annotation.runtime, the JUnit-free machinery that
resolves the annotations and drives a test's setup, verification,
teardown, and row count check: AnnotatedTestConfiguration and
AnnotatedTestExecutor as the entry points, the SetupTeardownLifecycle,
ExpectedLifecycle, and AnnotatedRowCountCheck steps they drive, and the
resolver and support classes behind them, plus
org.dbunit.DatabaseTesterFactory.

Extend RowCountChecker with per-scope enable and table-exclude
overrides, and clearEnabledOverride() to reset them for a checker reused
across test methods, so @DbUnitRowCountCheck can override
DatabaseConfig.FEATURE_ROW_COUNT_CHECK for a class or method while the
dbunit.rowCountCheck system property still wins outright.

Add IDatabaseTester#getOperationListener() (a default method,
implemented in AbstractDatabaseTester) so listener wiring wraps the
tester's existing IOperationListener instead of discarding it.

Widen the PrepAndExpectedTestCase interface with default methods -
tester, data file loader, failure handler, close-connection,
DatabaseConfig properties, and row count check override hooks - that a
binding calls on a @DbUnitTestCase-injected instance to push
@DbUnitConfig-resolved values into it after construction;
DefaultPrepAndExpectedTestCase overrides each, and its getReusableConnection()
is promoted to a public interface method.

Factor the per-test connection lifecycle shared by the setup/teardown
and prep/expected paths into org.dbunit.database.connection -
TestScopedConnection (acquire once, memoize, re-acquire a connection the
pool or server closed between reused test methods, release only when
this lifecycle owns the close), ConnectionOwnership (the close-or-keep
decision), and AutoCommitOffWarning - and promote the connection-preserving
listener DefaultPrepAndExpectedTestCase had inline to a top-level
org.dbunit.ConnectionPreservingOperationListener. Move
DefaultPrepAndExpectedTestCase onto them: its 3.5.2 non-autocommit
warning and closed-connection replacement move into these classes
unchanged in effect, and a tester IOperationListener that is or wraps
NO_OP_OPERATION_LISTENER now also stops setupData()/cleanupData() from
closing the shared connection when closeConnectionAfterTest is true.

Note: these are not yet wired into any JUnit binding.

Drive a test through org.dbunit.annotation via
AnnotatedTestConfiguration and AnnotatedTestExecutor: the prep/expected
path, @DbUnitConfig-driven tester and test-case resolution, @nested test
class support, the @DbUnitTest composed annotation, and a
ParameterResolver for IDatabaseTester, PrepAndExpectedTestCase,
IDatabaseConnection, and java.sql.Connection parameters.

The resolver is claimed only for a test that opts into the annotations -
one carrying a @dbunit* annotation or a @DbUnitTester or @DbUnitTestCase
field - so a bare @ExtendWith(DbUnitExtension.class) class with a plain
IDatabaseTester field never competes with another extension;
@DbUnitConfig(injectConnectionParameter = false) drops just the
java.sql.Connection claim for a co-registered resolver such as Spring or
Testcontainers.

Capture the @DbUnitRowCountCheck baseline before test execution and
verify it after, skipping the verify when the test itself failed so the
check never masks the real failure.

A zero-annotation test keeps the existing non-annotation lifecycle
exactly: onSetup, onTearDown, and the row count check run around the
test without the extension wrapping the tester's IOperationListener or
holding its connection past onSetup; the wrapping, connection
memoization, and parameter injection are reserved for a test that opts
in.

Integration-test the connection-ownership machinery under the
combination behind issues 962, 964, and 965:
* a CachingConnectionProvider
* closeConnectionAfterTest = false
* an active row count check
* a @DbUnitTestCase instance reused across methods
* an autocommit-off connection

Add ITs:
* DbUnitExtensionConnectionReuseIT - a pool-killed connection mid-run is
  re-acquired; prep data is committed and visible through a separate
  connection.
* DbUnitExtensionAutoCommitOffIT - the autocommit-off WARN fires and
  nothing the test writes persists.
* DbUnitExtensionRealTesterRowCountCheckIT - a real
  fresh-connection-per-call JdbcDatabaseTester through the baseline
  piggyback and memoize path; a leak into an unlisted table fails the
  check.
* DbUnitExtensionBoundedPoolIT and DbUnitExtensionConnectionBalanceIT
  - CountingDataSource pins exact peak concurrency, 1 for the
  prep/expected path and 2 for the setup/teardown path, and asserts
  zero leaked connections.
* DbUnitExtensionSelfManagedTestCaseIT - a composition
  PrepAndExpectedTestCase that manages its own tester and connection.
