# Test Only Library for Kotlin

This directory (`/lib/kotlin`) contains test only library code for Kotlin code gen. Because Kotlin code gen produces code that works on top of libthrift (i.e. Java library), the purpose of this library is to encode the cross test server and client to make sure it conforms to the thrift specifications.

The output artifact in this library is _not_ published to Maven central. Unlike the Java library where:

1. source code is put under `main` sources set i.e. `src/main`,
2. unit test code is put under `test` sources set i.e. `src/test`,
3. cross test code is put under `crossTest` sources set, i.e. `src/crossTest` directory which, unlike the default `main` and `test`, is created and configured on demand;

this kotlin library uses a multi-module project setup for separation of concern:

1. root module for configuring unit tests,
2. `cross-test-client` module for bundling a standalone test client,
3. `cross-test-server` module for bundling a standalone test server

## How to compile

This library is managed using Gradle 6.9.2, run the following command (requires C++ thrift compiler):

```bash
gradle build
```

```bash
gradle installDist
```

## How to run cross test server / client

```bash
gradle :cross-test-server:run
```

```bash
gradle :cross-test-client:run
```
