Csla.Net with Bunit

[ashishsinha24]

Hi,

Congratulations on creating an amazing library.

I am just starting out with Bunit. I have understood most of things, but am stuck on a silly issue.
Csla.Blazor injects a ViewModel into a page

@page "/"
@using ProjectTracker.Library
@inject Csla.Blazor.ViewModel<Dashboard> vm

and then this Viewmodel exposes the properties which can be used in the blazor page.

@if (vm.Model != null)
{
  <table>
    <tbody>
      <tr><td>Projects</td><td>@vm.Model.ProjectCount</td></tr>
      <tr><td>Open projects</td><td>@vm.Model.OpenProjectCount</td></tr>
      <tr><td>Resources</td><td>@vm.Model.ResourceCount</td></tr>
    </tbody>
  </table>
}

The viewmodel can be initialized by

protected override async Task OnParametersSetAsync()
{
  await vm.RefreshAsync(() => Csla.DataPortal.FetchAsync<Dashboard>());
}

My problem is , how do I inject and use it in my test.

Hi @ashishsinha24

Thank you. You inject things by registering them with your TestContext.Services collection, to learn more, see https://bunit.dev/docs/providing-input/inject-services-into-components.html.

E.g.:

using var ctx = new TestContext();

// Register services
var dashboardViewModel = ... something here;
ctx.Services.AddSingleton<Csla.Blazor.ViewModel<Dashboard>>(dashboardViewModel);

var cut = ctx.RenderComponent<Index>();

Thanks for the interest.
I have already tried it.

Cannot convert from Dashboard' to 'System.Func<System.IServiceProvider, Csla.Blazor.ViewModel<Dashboard>>

Not sure i can help any more. Registering the right service implementation is how you inject services into components with bUnit. It's very similar to the regular blazor runtime in that regard.

I think you need to ask for help from the csla community on this one. I'm am not familiar with it so cannot really help with regards to it.

Already did so.
