@Test
public void testExtractWalPathInfo_withPrefix()
                                       throws Exception

extractWalPathInfo: happy path where WALs dir has a prefix. e.g. /some/prefix/WALs/2025-09-14/some-wal

Throws:

Exception

testExtractWalPathInfo_rootWALs

@Test
public void testExtractWalPathInfo_rootWALs()
                                     throws Exception

extractWalPathInfo: case where WALs is at root (leading slash). e.g. /WALs/2025-09-14/some-wal Expect prefixBeforeWALs to be "/" (root) or non-null; resolution should still work.

Throws:

Exception

testExtractWalPathInfo_nullPath

@Test
public void testExtractWalPathInfo_nullPath()
                                     throws Exception

extractWalPathInfo: null input should throw IllegalArgumentException.

Throws:

Exception

testExtractWalPathInfo_missingDateDir

@Test
public void testExtractWalPathInfo_missingDateDir()
                                           throws Exception

Throws:

Exception

@Test
public void testResolveBulkLoadFullPath_withPrefix()
                                            throws Exception

resolveBulkLoadFullPath: normal case with prefix.

Throws:

Exception
