TelegramFunction Integration Test

[dgor82]

Implementing this test is more complicated than I thought, will leave for later. See: https://chat.openai.com/share/e9f1388e-d789-4c41-9637-2f4ffe5d4cb1

Below, initial attempt at coding

public class TelegramFunctionTests
{
    private ServiceProvider? _services;

    [Theory]
    [InlineData(BotType.Submissions)]
    [InlineData(BotType.Communications)]
    [InlineData(BotType.Notifications)]

    [Fact]    
    public async Task SubmissionsBot_RespondsWithOk_ForValidUpdate()
    {
         _services = new IntegrationTestStartup().Services.BuildServiceProvider();

        var mockLoggerBot = new Mock<ILogger<SubmissionsBot>>().Object;
        var updateHandler = _services.GetRequiredService<IBotUpdateHandler>();
        var submissionsBot = new SubmissionsBot(mockLoggerBot, updateHandler);

        const long validUserId = 123L;
        const string validText = "Valid text message";
        var now = DateTime.Now;

        var update = new Update
        {
            Message = new Message
            {
                From = new User
                {
                    Id = validUserId,
                    IsBot = false,
                    FirstName = "Daniel"
                },
                Date = now,
                Text = validText,
                Chat = new Chat()
            }
        };

        var jsonString = JsonConvert.SerializeObject(update);
        var stream = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));

        var requestMock = new Mock<HttpRequestData>();
        requestMock.Setup(x => x.Body).Returns(stream);

        var response = await submissionsBot.Run(requestMock.Object);

        response.Should().Be(HttpStatusCode.OK);
    }
