Alternatively you inject ProtectedBrowserStorage into your components that use PSS currently, and configure your services provider to return a PSS when a component asks for ProtectedBrowserStorage.
ProtectedBrowserStorage is abstract which means it's mockable.
But again, I would create a class you own that takes a PSS in its ctor and otherwise mimicks it's interface, but just forwards to the PSS. Then you can make your class mockable, and it's one you own.
internal class MyProtectedSessionStorage{
private ProtectedSessionStorage pss;
public MyProtectedSessionStorage(ProtectedSessionStorage pss)
=> this.pss = pss;
public virtual TValue GetAsync<TValue>(string key) => pss.GetString<TValue>(key);
...
}

Hey, question, I'm trying to use bUnit from source, and also trying to use Microsoft.AspNetCore.Components / Microsoft.AspNetCore.Components.Web from source, (because I'm debugging something)
However, when I point bUnit to the sources instead of the nuget, I'm getting loads of errors about missing namespaces from System.ComponentModel : https://i.imgur.com/tDP8ld8.png
Anyone have an idea how to solve this? It kinda seems like I'm missing some implicit usings, because the namespaces aren't in the files either

context.RenderComponent<>(); with my component, it just throws a null reference exception without telling me anything useful. Something in my component is null. I was trying to see if I can add a fix somewhere to tell me exactly what is null, if that's possible. The exception is being thrown from somewhere inside base.ProcessPendingRender();
alright sure. I think it's pretty easy to reproduce. You kinda just have to make a .razor file throw a null reference exception. Maybe you have bind null to something that's not expecting it, but that's it.
in my project I made a null check helper extension which is like this public static bool IsNull(this object input, [CallerArgumentExpression("input")] string message = null, [CallerMemberName] string caller = "")
and actually tells you which expression threw the null exception. Was hoping I could add something similar in whatever is throwing that null exception during rendering

Hello. I thought I'd join the chat, as I'm using BUnit and really liking it. I have and I'm going to have questions/general thoughts. I should buy you a coffee, Egil, if it's not too expensive in Iceland!
One thing that I think would be useful and something that I am happy to contribute to is the documentation around how to use event handlers with some basic types and then how to check results. I found myself struggling with checking the state of the HTML after a change. I can use var cut = ctx.RenderComponent<HelloWorld>() and check cut.Markup but after an event click on a radio button, cut.Markup is still the same, and I'm not sure what is the best way to get the revised Markup (this may just be that I am missing something).
