Blazorme.TestHost

Support library for Blazor component unit testing. The source code is taken from Steve Sanderson's BlazorUnitTestingPrototype project. See his blog post for more details. His project is available only as source code; this package makes it usable as a dependency.

Consider bUnit first

bUnit grew out of the same prototype and is the actively maintained library for this job. For a new test suite, prefer it. This package exists for projects already built on it.

Requirements

Targets net8.0 and net10.0. Earlier versions targeted netstandard2.1 and net5.0; those are no longer supported.

.NET 8 is included deliberately. A net10.0-only package would leave every project on .NET 5 to .NET 9 resolving 1.0.0, which crashes at runtime (see below), so those users would be worse off than before.

Version 1.0.0 did not work on .NET 5 or later, despite advertising that it did. Duplicate PackageReference items meant its net5.0 build was compiled against ASP.NET Core 3.1, whose RenderTreeFrame exposed public fields that became properties in .NET 5. Rendering a component threw MissingFieldException at runtime. Fixed in this release.

Installation

  Install-Package Blazorme.TestHost

Usage

  using Blazorme;

  var host = new TestHost();
  host.AddService<IMyService, IMyService>(myServiceStub);

  var component = host.AddComponent<MyComponent>();

  component.Find("button.submit")?.Click();
  component.GetMarkup().Should().Contain("Saved");

Find returns null when the selector matches nothing; FindAll returns every match. Both accept CSS selectors, resolved by Fizzler over the rendered markup.

1.0.0 9,719 12/2/2020 1.0.0 is deprecated because it has critical bugs.

Modernised for .NET 10, and multi-targeted so .NET 8 projects have a working version too. netstandard2.1 and net5.0 are no longer supported.
Fixed: version 1.0.0 did not work on .NET 5 or later at all, despite advertising .NET 5 support. Duplicate PackageReference items meant both of its builds were compiled against ASP.NET Core 3.1, whose RenderTreeFrame exposed public fields that later became properties, so rendering a component threw MissingFieldException at runtime.
