Bunit & Csla.Blazor

[ashishsinha24]

I am trying to use Bunit to test my Csla Blazor project, but am stuck up in basics.

I am initialising my XUnit constructor with this code.

public ControlTest()
{
Services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme).AddCookie();
Services.AddCsla().WithBlazorServerSupport();

        `CslaConfiguration.Configure().DataPortal().
            DefaultProxy(typeof(Csla.DataPortalClient.HttpProxy), "http://localhost:8040/api/dataportal/");`

        `Csla.ApplicationContext.User = new GenericPrincipal(new GenericIdentity("test"), new[] { "Administrator", "ServiceManager" });`

        `var credentials = Csla.DataPortal.Create<Credentials>("admin", "admin");`
        `var validator = Csla.DataPortal.Fetch<CredentialValidator>(credentials);`
        `var principal = validator.GetPrincipal();`

        `Csla.ApplicationContext.User = principal;`

        `if (principal.Identity.IsAuthenticated)`
        `{`
            `AuthenticationProperties authProperties = new AuthenticationProperties();`
            `App.ApplicationUser = validator;`
        `}`

    `}`

And trying to run this test.

[Fact]
public async Task TextInputTest()
{
// Arrange
ViewModel<ServiceEdit> vm = new ViewModel<ServiceEdit>();
await vm.RefreshAsync(() => DataPortal.CreateAsync<ServiceEdit>(1));

        `Services.AddSingleton<ViewModel<ServiceEdit>>(vm);`

        `var component = RenderComponent<TextInput>(`
        `Parameter(nameof(TextInput.Property), vm.GetPropertyInfo("ServiceName")));`

    `}`

But unfortunately I cant even compile this. How do I pass my ViewModel to the test?
Any help would be be nice.

I've never used bunit.

Normally you need to configure CSLA differently for a unit test framework/runtime than for a normal (aspnet, blazor, winforms) runtime.

In other words, Services.AddCsla().WithBlazorServerSupport() is designed to configure CSLA to run inside server-side Blazor, not a unit test runtime.

Thanks,

How can I create a New Blazor ViewModel(). It expects a parameter of type IDataportal.
How can I get it from my businessobject?

It is designed to use dependency injection, and so in a normal setting it would get that value injected automatically.

When building unit tests you either set up DI, or do it by hand. Either way, you normally inject a mock of the type, rather than the real thing. In other words, you probably don't provide an actual data portal instance, but rather use a mocking tool (Rocks, MOQ, etc.) to create a mock of IDataPortal to pass into the constructor.
