This new example project show four testing strategies for Swift Lambda function - Unit testing the business logic (not specific to Swift Lambda) - Integration testing the handler method - Local invocation with the Swift Lambda Runtime - Local invocation with SAM **[IMPORTANT]** To allow testing the handler, I had to change visibility of a method in the Runtime project. This method is clearly marked for testing only, so it should not be a problem. Happy to read feedback and discuss however.
