Disable logs when doing integration tests

Summary

This extension allows you to configure the log level when running integration tests.

Motivation

I want to be able to do integration tests as defined in introduction to integration tests but I don't want any logs to be produced.

By default when running integration tests you will see several log messages from the test server starting up as well as from the requests being made to the test server. These might clutter your output specially in build pipelines.

Requirements

You will have to add the dotnet-sdk-extensions-testing nuget to your test project.

How to use

Start by creating an integration test as shown in introduction to integration tests. After you can disable logs as follows:

public class ConfigurationDemoTests : IClassFixture<WebApplicationFactory<Progam>>
{
    private readonly WebApplicationFactory<Progam> _webApplicationFactory;

    public ConfigurationDemoTests(WebApplicationFactory<Progam> webApplicationFactory)
    {
        _webApplicationFactory = webApplicationFactory;
    }

    [Fact]
    public async Task DemoTest()
    {
        var httpClient = _webApplicationFactory
            .WithWebHostBuilder(builder =>
            {
                builder
                    .UseDefaultLogLevel(LogLevel.None)
                    .ConfigureTestServices(services =>
                    {
                        // inject mocks for any other services
                    });
            })
            .CreateClient();

        // rest of test
    }
}

Alternatively you can set the log level to LogLevel.Critical which will hide all logs except critical ones which you might be interested in seeing in the log output.
