Static Guid

Consider the following code;

public static class StaticKeys
{
	public static Guid StaticPersonKey = new("C8901F9D-4227-4BAC-903F-46E899D863F4");
}

Using Stryker would result in:

public static class StaticKeys
{
	public static Guid StaticPersonKey = new("");
}

This will always throw because an empty string can not be parsed as a Guid. It would be great if Stryker in this case mutated to Guid.Empty or some random Guid. Maybe configurable?

@Liam-Rougoor well yes and no. We already do this for regex as well. If we find a string in a constructor called “Regex” we assume the string is a regex and we mutate regex specifically.

We could do the same with Guid. It’s not foolproof as with the above anonymous constructor we can’t find the name. Or someone could have their own class called Guid (but why would they…).

So basically, yes we can do this. But only if the syntax new Guid("C8901F9D-4227-4BAC-903F-46E899D863F4") is used.

@Iceeman76 : bear in mind that this behavior is considered as normal for Stryker: there is no strong guarantee that generated mutations are relevant (while ensuring of them are, of course). So this is definitely a low priority request, until proven otherwise.

That being said, it looks like something that can be addressed simply by configuration: you just need to add *.Guid.ctor as to be ignored. See the configuration doc for details.
