            func init() vs func main() for initalizing global state in AWS Lambda handlers
            Asked 2021-Jun-03 at 16:35

            Looking at the Using global state section in the official AWS Lambda function handler in Go doc

            suggests to initialise all global state in func init() i.e. Any package level vars which we want to share across multiple lambda invocations go here.
            And my understanding is that this initialisation is done once per lambda container start (i.e cold start).

            My question is, is it possible to do the same using func main() instead of func init().
            Using func init() basically makes my handler function (func LambdaHandler) non unit-testable due to side-effects from func init() running.
            Moving the func init() code to func main() seems to solve this easily.
            Are there any side effects to using func main() vs func init()

            Code Example

            Operation not permitted when executing an arbitrary binary
            Asked 2021-May-14 at 10:57

            In Running arbitrary binary, AWS explains:

            Including your own executables is easy; just package them in the ZIP file you upload, and then reference them (including the relative path within the ZIP file you created) when you call them from Node.js or from other processes that you’ve previously started. Ensure that you include the following at the start of your function code: process.env[‘PATH’] = process.env[‘PATH’] + ‘:’ + process.env[‘LAMBDA_TASK_ROOT’] You can use all the usual forms of interprocess communication as well as files in /tmp to communicate with any of the processes you create.

            Answered 2021-May-08 at 19:18

            You've downloaded the Terraform binary as a zip file, so it isn't in a form that can be executed.

            You'll need to decompress it before repackaging it with zip.

            Are you importing both and If so, try importing the former with:

            Unit tests panic when returning dereferenced struct attribute rather than struct
            Asked 2021-Jan-18 at 09:15

            How does one go about testing a function that is returning a struct attribute that is of type string or number, rather than the struct itself?

            I am trying to test the Lambda Code block with the Test Code block.

            In Lambda Code block below, I am returning *resp.UserPoolClient.ClientSecret which dereferences to a string, rather than the *string.

            When I run my test, I believe I get a panic error as *resp.UserPoolClient.ClientSecret is nil in the debugger.

            Is my returning of the de-referenced attribute the wrong approach? Wondering if I'm better off just returning the whole resp object, not de-referenced? I was doing it this way as I didn't need to modify the values at all, just needed copies available for reference.

            Lambda Code

            Is my returning of the de-referenced attribute the wrong approach?

            Personally, I don't think it is wrong. I would do the same. But more seasoned Go developers might be able to contribute a more nuanced and detailed answer here.

            In regards to the panic, I think the issue is that the mock you create does not return all the required information.

            AWS SDK Go Lambda Unit Testing
            Asked 2020-Dec-27 at 13:32

            I'm trying to wrap my head around writing some unit tests for the first time ever, and I'm doing it in golang for a side project utilising aws lambda.

            Below are two files.

            main.go takes an event containing an email address, and creates the user in a cognito user pool.

            main_test.go is supposed to mock the createUser function in main.go, but I'm getting an error when I try to run the test.

            I've just switched my code from instantiating the client globally to using pointer receiver methods on the aws sdk interfaces after watching this youtube video.




            Answered 2020-Dec-27 at 13:32

            I think the issue here is, that you wanted to mock the AdminCreateUser() method, but did actually mock the CreateUser() method.

            Therefore, when you create a new instance of the mockCreateUser struct, that "implements" the cidpif.CognitoIdentityProviderAPI interface, and then call the AdminCreateUser() method on it, it is not implemented and fails.

            The relevant code in your main_test.go should be this:

            as per documetation The handler parameter must match the name of the executable containing your handler.

            have you updated the handler name in the lambda configuration to main

            by default its set to hello

            Update it to main

            Your else needs to be inline with the } closing the if.
