Unable to resolve service for type ILogger

[InzeNL]

Describe the bug
I am running into a problem trying to test my Blazor app which uses Blazorise. When I try to render my component Index (initially occurred with another page, but also happens with my very simple Index page), it throws an error saying it's unable to resolve a service for the type ILogger. I cannot find a proper way to inject this, but I also think this is not the proper way to fix it anyway.

Initially I ran into the problem of the test not being able to inject IConfiguration, but I "fixed" this by using services.AddSingleton<IConfiguration>(new ConfigurationBuilder().Build());.

I am thinking that something went wrong before that already. In the bUnit documentation, I don't see any configuration being specified, so my guess is I'm already doing something wrong there.

Since the error does not seem to contain Blazorise calls, I assume it's an issue with bUnit, not with Blazorise. If it is, please let me know so I can close this ticket here and move it to the Blazorise repository.

Example:
Testing this component:

App.razor

@using WeedIt.Web.Pages.Elements
<Blazorise.ThemeProvider Theme="@_theme">
    <Router AppAssembly="@typeof(Program).Assembly" PreferExactMatches="@true">
        <Found Context="routeData">
            <RouteView RouteData="@routeData" DefaultLayout="@typeof(MainLayout)"/>
        </Found>
        <NotFound>
            <LayoutView Layout="@typeof(MainLayout)">
                <p>Sorry, there's nothing at this address.</p>
            </LayoutView>
        </NotFound>
    </Router>
</Blazorise.ThemeProvider>

MainLayout.razor

@inherits LayoutComponentBase

<Layout Sider="true">
    <LayoutSider>
        <LayoutSiderContent>
            <NavMenu/>
        </LayoutSiderContent>
    </LayoutSider>

    <Layout Padding="Padding.Is5">
        <LayoutContent>
            @Body
        </LayoutContent>
    </Layout>
</Layout>

Index.razor

@page "/"

<h3>My page</h3>

<Paragraph>
    Some text here
</Paragraph>

With this test:

var testContext = new TestContext();

var services = testContext.Services;
services.AddRazorPages();
services.AddServerSideBlazor();
services.AddBlazorise(options => { options.ChangeTextOnKeyPress = true; });
services.AddBootstrapProviders();
services.AddFontAwesomeIcons();

services.AddSingleton<IConfiguration>(new ConfigurationBuilder().Build());

_renderedComponent = testContext.RenderComponent<Index>();

Results in this output:

Unable to resolve service for type 'Microsoft.Extensions.Logging.ILogger`1[Microsoft.AspNetCore.Components.Server.Circuits.RemoteJSRuntime]' while attempting to activate 'Microsoft.AspNetCore.Components.Server.Circuits.RemoteJSRuntime'.

Looking at the actual error message, I see you are trying to set up the runtime to use remote JSInterop and SinglR circuit, most likely because you call AddServerSideBlazor. bUnit doesnt run a browser, so there is no need for JSInterop. This needs a ILogger, but you should not use any of that with bUnit.

But to answer your question, here is an example of setting up logging while testing: https://bunit.dev/docs/misc-test-tips.html#capturing-logs-from-ilogger-in-test-output

@stsrki can probably guide you to what is need to configure bUnit's TestContext to render Blazorise components.

Im moving this to the discussion forum as this is not a bug.

@InzeNL As @egil already mentioned, JSInterop is unavailable since it doesn't run a browser. Same with ILogger probably. You can always look at the Blazorise test code for reference https://github.com/Megabit/Blazorise/tree/master/Tests/Blazorise.Tests. It was done mostly by the community members and it works well for our use cases.

Also is you need a fully working test code that runs in the browser you can see our E2E tests. They are somewhat slower and harder to maintain but are closest to the real thing as possible https://github.com/Megabit/Blazorise/tree/master/Tests/Blazorise.E2ETests
