Demonstrates how you can handle the case where you want to declare a Kotlin property as not being nullable but not specify a value at declaration time.
The approach used here is to use the Delegates.notNull property delegate which returns a property delegate for a read/write property with a non-null value that is not initialised during object construction.
Two JUnit 5 tests are provided demonstrating that:
- an exception is thrown if the property is accessed prior to initialisation; and
- the value can be accessed as usual once the property has been initialised.
