Code review comment: This has been verified in the other test. We don't need to test it again here.

Code under review:
public void testTableSourceWithPattern() {
		
		final DataType producedDataType = SOURCE_SCHEMA.toPhysicalRowDataType();

		final Map<KafkaTopicPartition, Long> specificOffsets = new HashMap<>();

		DecodingFormat<DeserializationSchema<RowData>> decodingFormat =
			new TestFormatFactory.DecodingFormatMock(",", true);

		
		ObjectIdentifier objectIdentifier = ObjectIdentifier.of(
			"default",
			"default",
			"scanTable");

		final Map<String, String> modifiedOptions = getModifiedOptions(
			getFullSourceOptions(),
			options -> {
				options.remove("topic");
				options.put("topic-pattern", TOPIC_REGEX);
				options.put("scan.startup.mode", KafkaOptions.SCAN_STARTUP_MODE_VALUE_EARLIEST);
				options.remove("scan.startup.specific-offsets");
			});
		CatalogTable catalogTable = createKafkaSourceCatalogTable(modifiedOptions);

		final DynamicTableSource actualSource = FactoryUtil.createTableSource(null,
			objectIdentifier,
			catalogTable,
			new Configuration(),
			Thread.currentThread().getContextClassLoader());

		
		final KafkaDynamicSourceBase expectedKafkaSource = getExpectedScanSource(
			producedDataType,
			null,
			Pattern.compile(TOPIC_REGEX),
			KAFKA_PROPERTIES,
			decodingFormat,
			StartupMode.EARLIEST,
			specificOffsets,
			0);
		final KafkaDynamicSourceBase actualKafkaSource = (KafkaDynamicSourceBase) actualSource;
		assertEquals(actualKafkaSource, expectedKafkaSource);

		
		ScanTableSource.ScanRuntimeProvider provider =
			actualKafkaSource.getScanRuntimeProvider(ScanRuntimeProviderContext.INSTANCE);
		assertThat(provider, instanceOf(SourceFunctionProvider.class));
		final SourceFunctionProvider sourceFunctionProvider = (SourceFunctionProvider) provider;
		final SourceFunction<RowData> sourceFunction = sourceFunctionProvider.createSourceFunction();
		assertThat(sourceFunction, instanceOf(getExpectedConsumerClass()));
		
		assertTrue(((FlinkKafkaConsumerBase) sourceFunction).getEnableCommitOnCheckpoints());
	}

Line commented on: assertTrue(((FlinkKafkaConsumerBase) sourceFunction).getEnableCommitOnCheckpoints());

Revised code:

				options.remove("scan.startup.specific-offsets");
			});
		CatalogTable catalogTable = createKafkaSourceCatalogTable(modifiedOptions);

		final DynamicTableSource actualSource = FactoryUtil.createTableSource(null,
			objectIdentifier,
			catalogTable,
			new Configuration(),
