Fluent Assertions tests

[agriffard]

Try to use https://github.com/fluentassertions/fluentassertions in tests.

I might disagree because we already using xUnit. We could use some extensions to simplify the assertion rather than introducing a new library that will change the entire unit tests

Damn, a thumb down emoji.

Don't take it in person :) I might create a PR in the future to simplify some assertions which will do the exact same thing. Thanks to point to this

There are no tests on this class:

OrchardCore/src/OrchardCore/OrchardCore.ContentManagement.Abstractions/Utilities/StringExtensions.cs

Line 12 in 4562415

public static class StringExtensions

There are multiple StringExtensions.cs files in different modules that add different extensions methods which are not tested.

If we manage to list some of them, we could open some issues labelled good first issue.
