Quarkus Amazon Lambda extension and testing multiple handlers

I have a Quarkus project with a few different Lambda handlers.

In order to 'deploy' or 'select' the handler to use, the documentation states that we should set the quarkus.lambda.handler application.properties setting, or QUARKUS_LAMBDA_HANDLER environment variable accordingly.

E.g.

quarkus.lambda.handler=my-handler

The handler is named with the @Named annotation. E.g.

@Named("my-handler")

The application.properties setting or environment variable works for selecting a single handler for testing purposes, but I run into trouble when trying to test multiple handlers in one go in the project.

I've tried using a System property to set quarkus.lambda.handler in the hopes that it would override the setting, and also tried modifying the live JVM system environment variables using my test setup method (@BeforeAll), however I think that the test run caches environment variables at the start, and so modifying things during a test session doesn't work.

Is there a known or valid way to test multiple quarkus lambda function handlers in a project without having to edit the application.properties file each time I want to test a different handler?

If I understood correctly your problem you could use QuarkusTestProfile just implements this interface and return something like this

@Override
public Map<String, String> getConfigOverrides() {
        return Map.of("quarkus.lambda.handler", "name-of-the-handler");
}

After this annotate your test with @TestProfile(ClassImplementingQuarkusTestProfile) and this should be enough to let you run it.

Unfortunately after you have multiple handlers you have to set the TestProfile for all the tests.
