- Adds `LanguagePrimitives.IsNullLike()` method to account for `DBNull.Value` and `NullString.Value` so that they can be considered the same as a null value where sensible in PowerShell. - Updates `-ne` and `-eq` binders to treat `DBNull.Value` and `NullString.Value` as equal to null/AutomationNull. - Update code paths for comparing objects in LanguagePrimitives to ensure consistency with how the `-eq` and `-ne` binders work when calling LanguagePrimitives methods to do the comparisons. - Make `LanguagePrimitives.IsNull()` and `LanguagePrimitives.IsNullLike()` public methods. - Added tests for null behaviours in `NullRepresentatives.Tests.ps1`
Testing
The tests are organized by testing language. Thus Pester tests, which are written in the PowerShell language, are in ./powershell and xUnit tests, written in C#, are in ./xUnit. The third-party shebang test is in ./shebang.
