Thanks @0lai0 for the patch.
I have few more test case suggestions which could be added.

[Gargi-jais11]

testPutObjectTagging()and testGetObjectTagging(), are functionally very similar and could be merged into a single test named as testPutAndGetObjectTagging().

More Edge Cases which can be tested:

1. testPutObjectTaggingExceedsLimit() — Test 11 tags and validate it throws error there is 10-tag limit.
2. testPutObjectTaggingReplacesExistingTags() — verifies replacement behavior (Initially put 2 tags then replace it with 1 tag and check the last replcaed tag is only applied)
3. testPutObjectTaggingInvalidConstraints - This can be a parameterised test like below:

private static Stream<Arguments> invalidTagConstraintsProvider() {
    return Stream.of(
        // Test 1: Tag key exceeds maximum length (128 bytes)
        Arguments.of(
            "Tag key exceeding 128 bytes should be rejected",
            Arrays.asList(Tag.builder().key("a".repeat(129)).value("value").build()),
            400,
            "exceeds the maximum length"
        ),
        
        // Test 2: Tag value exceeds maximum length (256 bytes)
        Arguments.of(
            "Tag value exceeding 256 bytes should be rejected",
            Arrays.asList(Tag.builder().key("valid-key").value("b".repeat(257)).build()),
            400,
            "exceeds the maximum length"
        ),
        // Test 3: Tag key with invalid characters (@, #, $, (, {, ....)
        Arguments.of(
            "Tag key with invalid characters should be rejected",
            Arrays.asList(Tag.builder().key("t$ag@#invalid").value("value").build()),
            400,
            "does not have a valid pattern"
        ), 
        // Test 4: Tag key starting with "aws:" prefix
        Arguments.of(
            "Tag key starting with 'aws:' prefix should be rejected",
            Arrays.asList(Tag.builder().key("aws:test").value("value").build()),
            400,
            "cannot start with \"aws:\"" 
        )
    );
    }
@ParameterizedTest
@MethodSource("invalidTagConstraintsProvider")
public void testPutObjectTaggingInvalidConstraints(
    String testCaseName,
    List<Tag> invalidTags,
    int expectedStatusCode,
    String expectedErrorMessage) {
    // your code
}

4. testPutAndGetObjectTaggingOnNonExistentObject() - Verify NoSuchKeyException occurs and 404 status code.
5. testDeleteObjectTaggingOnNonExistentObject() - Verify NoSuchKeyException occurs and 404 status code.
