Aspire testing library

As explained in Building Distributed Applications that Work

Aspire.Hosting.Testing is a .NET package that provides components for testing Aspire applications.

Aspire.Hosting.Testing supplies components for integration testing Aspire applications. Its libraries work with xUnit, NUnit, and MSTest; xUnit is the default for the Aspire test-project template. section 6.6.1 section 6.6.2

To prepare a test project for testing the whole Aspire application:

  • Add a reference to the Aspire.Hosting.Testing NuGet package. section 6.6.2
  • Reference the application’s AppHost project from the test project. section 6.6.2
dotnet new aspire-xunit

Create an xUnit Aspire test project with the .NET CLI. section 6.6.1

How Building Distributed Applications that Work covers it

How deep it goes
Specifies test-project dependencies and setup, but stops short of detailing test implementation.
Examples
Uses an OnlineShop.Tests xUnit project and the aspire-xunit template command.
What it assumes
Assumes an existing Aspire application and demonstrates creating a test project and adding Aspire dependencies.
What you can do after
Configure a .NET test project for Aspire integration testing by adding the package and AppHost reference.
How it connects
Connects Aspire integration testing to .NET test projects, AppHost, xUnit, NUnit, and MSTest.
