Arbitrater is a library for creating arbitrary instances of classes by reflection,

for example to use in testing. It was designed primarily for use with Kotlin 'data classes', 

but may work with regular classes too.

It is similar to libraries like [random-beans](https://github.com/benas/random-beans) and

[podam](https://devopsfolks.github.io/podam/), but with support for nullable types and default values. 

## Quick start

```kotlin

data class Order(val name: String, val quantity: Int = 1, val promotionCode: String?)

val defaultOrder: Order = arbitrary()

println(defaultOrder) // Order(description=\VccV/esz{54[!FAU(a{, quantity=1, promotionCode=5b$`i1AsT54t[Hwf%W*&)    

val customOrder = Order::class.arbitrater()

        .generateNulls()

        .useDefaultValues(false)

        .createInstance()    

        

println(customOrder) // Order(description= 5{L_vUnvMIJ!y]03*
