📝 WalkthroughWalkthroughThe project adds an opt-in row-count diagnostic. It captures table counts before setup, compares them after teardown, supports exclusions and custom counters, integrates with both test lifecycles, and reports unexpected changes.

Release and documentation
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to The row-count feature currently has unresolved correctness and resource-lifecycle defects: dropped tables can cause an unexpected null failure while newly added tables are missed, setup can break cached database connections, and integration tests can exhaust database connections.

Hey - I've left some high level feedback:
- The store key for the row count checker is duplicated as a string constant in DbUnitExtensionRowCountCheckTest rather than reusing the production constant, which makes the test brittle if the key ever changes; consider exposing the key via a package-visible constant or helper to keep them aligned.

Inline comments:
In `@src/main/java/org/dbunit/database/rowcount/RowCountCheck.java`:
- Around line 92-126: Update RowCountSnapshot.difference to compare the union of
baseline and current row-count table keys, treating absent counts as zero so
dropped or newly added tables produce RowCountDifference entries rather than a
NullPointerException. Add tests in RowCountCheckTest for both a baseline table
missing during verification and a table added during verification; no direct
change is required in RowCountCheck.java because verify already delegates
comparison there.
Apply the same fix in
`@src/test/java/org/dbunit/database/rowcount/RowCountCheckTest.java` around lines
102 - 121.
In `@src/main/java/org/dbunit/junit/jupiter/DbUnitExtension.java`:
- Around line 148-160: Update captureRowCountBaseline in DbUnitExtension so it
does not close the tester-owned connection returned by tester.getConnection();
obtain and close a separately owned connection for baseline capture, while
preserving null handling and row-count capture. Add a regression test using a
fixed-connection DefaultDatabaseTester to verify onSetup() still receives an
open connection.
In `@src/site/asciidoc/components/rowcountcheck.adoc`:
- Around line 121-124: Update the repair guidance in the row-count check
documentation to state that adding a table to the expected dataset for
DefaultPrepAndExpectedTestCase also requires a matching VerifyTableDefinition by
default; retain the existing guidance for legitimate exclusions and tables that
should remain untouched.
- Around line 155-175: Update the prose introducing UnionAllRowCounter to
identify it as an illustrative sketch rather than a complete implementation, and
explicitly state that vendor-safe quoting and escaping of table identifiers and
SQL literals is required before use.
In `@src/site/asciidoc/index.adoc`:
- Around line 49-51: Update the snapshot announcement sentence near the
RowCountCheck description to say it catches tables that teardown missed or
wrongly cleaned, preserving the surrounding wording.
In `@src/site/asciidoc/properties.adoc`:
- Around line 178-180: Update the RowCounter API reference in the rowcounter
property documentation to use the root-relative
link:/dbunit/apidocs/org/dbunit/database/rowcount/RowCounter.html form, while
leaving the surrounding description and other links unchanged.
In `@src/site/asciidoc/testcases/DbUnitExtension.adoc`:
- Around line 60-70: Update the “Row Count Check” documentation to state that
verification is skipped when either the test method or teardown lifecycle
throws, matching the current onTearDown() and verifyRowCountUnchanged() behavior
in DbUnitExtension. Do not change the lifecycle implementation.
In
`@src/test/java/org/dbunit/database/rowcount/ClearRowCountCheckSystemPropertiesExtension.java`:
- Around line 40-62: The public callback methods beforeEach and afterEach in
ClearRowCountCheckSystemPropertiesExtension lack JavaDoc; add complete JavaDoc
before each method with a sentence-case description and a complete `@param`
description for the ExtensionContext context parameter, ending documentation
sentences with periods.
In `@src/test/java/org/dbunit/database/rowcount/QueryPerTableRowCounterTest.java`:
- Around line 84-95: Rename
testCountRows_getRowCountThrows_propagatesSQLExceptionNamingTheTable to reflect
that it verifies unchanged SQLException propagation without table naming, and
remove the redundant eq matcher by stubbing getRowCount with the raw "ACCOUNT"
argument. Delete the now-unused eq static import.
In `@src/test/java/org/dbunit/DefaultPrepAndExpectedTestCaseRowCountCheckIT.java`:
- Around line 75-82: Update cleanUp() to always close cleanupConnection in a
finally block after attempting both deleteAllRowsQuietly calls, preserving the
existing cleanup operations and handling any close failure consistently with the
method’s throws contract.

Addressed the review feedback from CodeRabbit and Sourcery, pushed as fixups (branch not yet merged to Fixed, including two real bugs:
Declined:
Full unit suite (2183 tests), HSQLDB integration tests, the field test with the check itself enabled ( |
Adds the core of an opt-in diagnostic that compares every table's row count before and after a test, catching both a table the developer forgot to list for teardown and a table they listed that should never have been cleaned. Not yet wired into any test lifecycle. * Add RowCounter (strategy interface) and QueryPerTableRowCounter (the v1 implementation, looping IDatabaseConnection.getRowCount()). * Add RowCountSnapshot and RowCountDifference as immutable values, and UnexpectedRowCountException to report every affected table with direction-specific advice. * Add RowCountCheckConfiguration to resolve enabled/exclude patterns/RowCounter from a dbunit.* system property, then DatabaseConfig, then defaults; and RowCountCheck to orchestrate table enumeration, exclusion filtering, and counting. * Register FEATURE_ROW_COUNT_CHECK, PROPERTY_ROW_COUNT_CHECK_EXCLUDE_TABLES, and PROPERTY_ROW_COUNTER on DatabaseConfig, defaulting to disabled. Refs: 939 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_018swDroagnZVcrgSHPWH7va
…e tests Wires RowCountCheck into DefaultPrepAndExpectedTestCase: preTest() captures the baseline before setupData(), cleanupData() verifies it after the tear down operation runs, and postTest(false) discards the baseline so a test that already failed does not also report a row count difference as noise. Both capture and verify reuse the connection shared with the rest of the test's lifecycle, so the check costs no extra physical connection. * Add getRowCountCheck()/setRowCountCheck(), consistent with the class's existing configuration style, so a custom RowCounter or configuration can be injected; otherwise one is lazily built from the shared connection's DatabaseConfig. * Add DefaultPrepAndExpectedTestCaseRowCountCheckIT, covering a row leaked into a table absent from prep/expected, a reference table wrongly listed for cleanup, and the exclude list silencing either - against a real database connection. * Document the check in testcases/PrepAndExpectedTestCase.adoc (where the underlying problem is felt) and recommend a periodic, not permanent, enabled run in bestpractices.adoc. Refs: 939 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_018swDroagnZVcrgSHPWH7va
Adds capture/compare to beforeTestExecution/afterTestExecution, reusing RowCountCheck unchanged. Each capture/verify acquires and closes its own connection from the resolved IDatabaseTester, independent of whatever connection onSetup()/onTearDown() use internally, so the check never entangles with the tester's own connection lifecycle (e.g. a shared CachingConnectionProvider). * Skip verification when the test method itself threw (ExtensionContext.getExecutionException().isPresent()), matching DefaultPrepAndExpectedTestCase's postTest(false) rationale: the database is in an unknown state, so a count difference would be noise around the real failure. * Tolerate IDatabaseTester.getConnection() returning null (e.g. a test double, as DbUnitExtensionLifecycleTest's CallLoggingTester already does) by simply never activating the check for it, rather than throwing. * Add DbUnitExtensionRowCountCheckTest. Refs: 939 Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_018swDroagnZVcrgSHPWH7va
Neither IT's makeDatabaseTester() ever called setTearDownOperation(), so their prep rows into TEST_TABLE, SECOND_TABLE, and PK_TABLE were never cleaned up - AbstractDatabaseTester defaults tearDownOperation to NONE. The leaked rows only masked themselves in the normal suite: whichever of these tests' own CLEAN_INSERT ran next happened to net back to the same row count. Enabling the new row count check (-Ddbunit.rowCountCheck=true) across dbUnit's own suite surfaced it directly, exactly the under-listing failure mode that check exists to catch. * Add DatabaseOperation.DELETE_ALL to both makeDatabaseTester() helpers.
