Invoke Kotlin tests via CLI

[ford-at-aws]

User story

As example code engineer, I want a way to execute “functional” integration tests for my language from a top-level directory using a single command.

By “functional”, I mean:

1. automation-friendly (no setup required)
2. passing without intermittent failures.

Acceptance criteria

I know this is done when:

• All functional integration tests can be executed on my machine from the CLI from the top-level (e.g. php/)

Had a call with Ford to go over this stuff.

To invoke a Kotlin test from command line - use gradle clean test -i
