WebApplicationFactory throws error that contentRootPath does not exist in ASP.NET Core integration test

Question

I have a ASP.NET Core project with some simple Razor pages and a Web API controller.

I\'m using Clean Architecture as a starting point. I\'ve renamed the project names,

Answer 1

My solution for this problem is define WebApplicationFactory with Application Startup but setup WebHostBuilder with TestStartup.

Example:

public class MyApplicationFactory : WebApplicationFactory
{
    protected override IWebHostBuilder CreateWebHostBuilder()
    {
        return WebHost.CreateDefaultBuilder();
    }

    protected override void ConfigureWebHost(IWebHostBuilder builder)
    {
        builder.UseStartup();

        base.ConfigureWebHost(builder);
    }
}
