CrossCutting

Generic utilities and other stuff, usable in any layer of any solution. We're targeting .NET Standard 2.0, so you can even use .NET Framework 4.x if you want to.

This repository consists of the following packages:

Using NSubstitute or Moq as mock factory for CrossCutting.Common.Testing

To use NSubstitute as a mock factory for the code in CrossCutting.Common.Testing, create a test helper project within your solution, and add the following code:

    public static void ShouldThrowArgumentNullExceptionsInConstructorsOnNullArguments(
        this Type type,
        Func<ParameterInfo, bool>? parameterPredicate = null,
        Func<ParameterInfo, object?>? parameterReplaceDelegate = null,
        Func<ConstructorInfo, bool>? constructorPredicate = null)
        => ShouldThrowArgumentNullExceptionsInConstructorsOnNullArguments(
            type,
            t => t.CreateInstance(parameterType => Substitute.For(new[] { parameterType }, Array.Empty<object>()), parameterReplaceDelegate, constructorPredicate),
            parameterPredicate,
            parameterReplaceDelegate,
            constructorPredicate);

You can easily replace NSubstitute with Moq, if you want, by changing the factory delegate argument to this:

t => t.CreateInstance(parameterType => ((Mock)Activator.CreateInstance(typeof(Mock<>).MakeGenericType(parameterType))).Object, parameterReplaceDelegate, constructorPredicate),

Upgrade from 2.x to 3.0

There has been a breaking change in the Result class, which lead to a new major version. To port the old code, you can fix most errors by replace this:

Result<([^>]+)>\.([^(]+)\(

With this:

Result.$2<$1>(
