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.
motivation: examples can be confusing since they use relative path to the library for CI purposes
changes:
* update examples to use the library URL, expect when env variable is set for CI purposes
* rename docker compose job to test-examples since it is more accurate
motivation: define stable API in preperation 1.0 release
changes:
* require swift 5.7, remove redundant backwards compatibility code
* make LambdaHandler, EventLoopLambdaHandler, and ByteBufferLambdaHandler disjointed protocols to reduce API surface area
* create coding wrappers for LambdaHandler and EventLoopLambdaHandler to provide bridge to ByteBufferLambdaHandler
* reuse output ByteBuffer to reduce allocations
* add new SimpleLambdaHandler with no-op initializer for simple lambda use cases
* update callsites and tests
* update examples

* take advantage of @main where possible
* move the top level Sample code to the examples subdirectory
* extract a few examples form the "LambdaFunctions" directory (which is really a deployment demo) and move them to the top level Examples directory
* rename "LambdaFunctions" examples as "Deployments" to make their intent clearer
* add a sample that demonstrates how to test a lambda now that SwiftPM can test executables directly
* update the test-sample docker setup to build & test th new samples
* fix a few typos and In/Out typealias left overs
* remove LinuxMain since its no longer required
