Thank you very much, sir.

Another good article is on https://automationrhapsody.com/net-core-integration-testing-mock-dependencies/

Great article! Could be improved using HttpClient rather than HttpClientFactory? How it works if web application have a lot of dependencies? All of them are stored in properties when tests starts.

Not sure what you mean. We're not using HttpClientFactory.

The only mocks you should have is for external systems like DB's.

Hi,

Thank you for the article.

However, I came across an issue when i tried this method.

this.ApplicationOptions = serviceProvider.GetRequiredService<IOptions>().Value;

The thing inside IOptions should be non-abstract, but ApplicationOptions is an abstract class.

Is there any possible way to fix that?

Cheers, Nicole

Getting error in CustomWebApplicationFactory.cs for this.Services.CreateScope() in ConfigureClient method. It does not recognize it. What is this.Services?

ApplicationOptions is just a class that I myself wrote to contain some custom configuration options. It doesn't have to be abstract.

The class inherits from WebApplicationFactory and that is where the Services property comes from.

You don' t need to extend startup to configure your test services for dotnet core 3+. IWebHostBuilder has a ConfigureTestServices extension method that will allow you to update the service registrations. In your custom web application factory override ConfigureWebHost and call the ConfigureTestServices method from there. This is documented here.

This is true. However, there was/is a known bug that stops this working at the time of writing. Also, I find that splitting it out into a separate class is helpful.
