WalkthroughThis update introduces three new test functions across different files to enhance test coverage. The additions include an IPv6 increment test for IP range logic, a test for byte conversion capping at the maximum integer, and a test verifying file reading without a custom filesystem. No production code was modified. Changes

Summary of Changes
Hello @ReneWerner87, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request focuses on enhancing the reliability and robustness of existing utility functions by expanding their unit test coverage. The changes introduce new test cases for critical edge scenarios, such as IPv6 address manipulation, handling of maximum integer values in conversions, and direct operating system file access, ensuring the functions behave as expected under diverse conditions.
Highlights
- Unit Test Coverage Enhancement: This pull request significantly increases unit test coverage for several utility functions, addressing specific edge cases and scenarios to improve overall code robustness.
- IPv6 Address Increment Testing: A new test case,
Test_IncrementIPRange_IPv6, has been added tocommon_test.goto verify the correct behavior of theIncrementIPRangefunction when dealing with IPv6 addresses, including handling of zero and all-ones addresses (wrap-around). ConvertToBytesMax Integer Handling: A new test,Test_ConvertToBytes_MaxInt, was introduced inconvert_test.goto ensure that theConvertToBytesfunction correctly caps input values atmath.MaxInt, preventing potential integer overflow issues for very large inputs.- OS-level File Reading Test: A test case,
Test_ReadFile_NoFS, has been added tofile_test.goto validate theReadFilefunction's ability to read files directly from the operating system when no explicitfs.FS(filesystem) is provided.

Code Review
The pull request adds new test cases to increase unit test coverage for IPv6 addresses, integer limits in ConvertToBytes, and OS-level file reading. The IPv6 test has a correctness issue, the ConvertToBytes test has a potential accuracy issue, and the file reading test is dependent on the file system.

The test compares the expected value with the input, but the input is modified by the IncrementIPRange function. It should compare with the value after the increment. This could lead to false positives if the increment logic is faulty.

The test case Test_ConvertToBytes_MaxInt uses integer division which might lead to unexpected results. Multiplying by a float before converting to an integer will be more accurate.
big := fmt.Sprintf("%dT", int64(float64(math.MaxInt)/1000+1))
require.Equal(t, math.MaxInt, ConvertToBytes(big))| data, err := ReadFile(".github/tests/john.txt", nil) | ||
| require.NoError(t, err) | ||
| require.Contains(t, string(data), "doe") |

The test Test_ReadFile_NoFS reads a file directly from the OS. This makes the test dependent on the file system and the presence of the .github/tests/john.txt file. This is not ideal for unit tests, as they should be isolated and reproducible. Consider using a mock file system for testing.
