Get IPnPContextFactory for class library

[wonderplayer]

Hello!

I'm trying to create integration tests with PnP.Core.
I'm able to constructor inject IPnPContextFactory as per documentation, but how can I set it up for class library, that doesn't have a startup class?

Thank you!

Never mind, I was really close to the answer myself :D
It's not the best, but if anyone is interested, here is how I got it:

    [TestClass]
    internal static class AssemblyInitialize
    {
        public static ServiceProvider ServiceProvider { get; private set; }
        [AssemblyInitialize()]
        public static void StartUp(TestContext context)
        {
            ApplicationSettings applicationSettings = TestCommon.GetAllSettings();

            var serviceProvider = new ServiceCollection()
                    .AddPnPContextFactory(options =>
                    {
                        var authProvider = new X509CertificateAuthenticationProvider(
                            applicationSettings.SharePointOnlineClientId,
                            applicationSettings.TenantId,
                            StoreName.My,
                            StoreLocation.CurrentUser,
                            applicationSettings.SharePointOnlineCertificateThumbPrint);
                        options.DefaultAuthenticationProvider = authProvider;
                    }
                ).BuildServiceProvider();
            ServiceProvider = serviceProvider;
        }
    }
