`Assert.AreEqual` on IEnumerable<DepartmentDto> (which implements IEnumerable<T>) does not perform element-wise sequence comparison. Use `Assert.AreSequenceEqual` for ordered element-wise comparison, `Assert.AreSequenceEqual(..., SequenceOrder.InAnyOrder)` for unordered, or `Assert.AreEquivalent` for deep structural comparison.

In externally visible method 'List<T> StringExtensions.SplitAndConvert<T>(string value, char separator, out bool allConverted)', validate parameter 'value' is non-null before using it. If appropriate, throw an 'ArgumentNullException' when the argument is 'null'. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1062)

In externally visible method 'string ExceptionHttpMapper.GetDetailMessage(Exception exception, bool isDevelopment)', validate parameter 'exception' is non-null before using it.
