I'm new to AWS server less programming. I've created a sample app. Blog(sample available with Visual Studio) using [.Net Core 1.0], now I want to deploy it locally and test it. I've tried AWS SAM Local and LocalStack but I'm confused as there is no clear explanation or steps for .Net Core application.

Can anyone provide me clear steps to deploy and execute this application locally?

The serverless sample out of the box from Amazon doesn't come with simple "press F5" way to run the code locally.

The easiest way to test your code locally is to create the sample with Unit Tests. These unit tests include everything you need to initialise Functions class so that you can run it. You could move this code into a simple console app or create unit tests that cover all the scenarios you want to test locally.

Here is the sample Unit Test from the project:

public class FunctionTest : IDisposable
{ 
    string TableName { get; }
    IAmazonDynamoDB DDBClient { get; }

    public FunctionTest()
    {
        this.TableName = "AWSServerless2-Blogs-" + DateTime.Now.Ticks;
        this.DDBClient = new AmazonDynamoDBClient(RegionEndpoint.USWest2);

        SetupTableAsync().Wait();
    }

    [Fact]
    public async Task BlogTestAsync()
    {
        TestLambdaContext context;
        APIGatewayProxyRequest request;
        APIGatewayProxyResponse response;

        Functions functions = new Functions(this.DDBClient, this.TableName);

        // Add a new blog post
        Blog myBlog = new Blog();
        myBlog.Name = "The awesome post";
        myBlog.Content = "Content for the awesome blog";

        request = new APIGatewayProxyRequest
        {
            Body = JsonConvert.SerializeObject(myBlog)
        };
        context = new TestLambdaContext();
        response = await functions.AddBlogAsync(request, context);
        Assert.Equal(200, response.StatusCode);

  • Thank you for the answer but I already know how to test APIs from Visual Studio, what I want know is, Is there any way to deploy serverless application in your local environment? As I said I've tried using AWS SAM Local and LocalStack. AWS SAM Local doesn't support dotnetcore runtime yet, and I don't know how to use locastack with dotnetcore as there is no documentation for dotnetcore application. – vishwas-trivedi Sep 12 '17 at 00:20
  • To be honest, I didn't even know AWS SAM Local was a thing. As you say, it doesn't support .NET Core at the moment. Hopefully that support is on its way. SAM Local supports the following AWS runtimes: node.js 4.3 node.js 6.10 python 2.7 python 3.6 java8 http://docs.aws.amazon.com/lambda/latest/dg/test-sam-local.html – Neil Bostrom Sep 12 '17 at 12:52
