MocKMP

A Kotlin/Multiplatform Kotlin Symbol Processor that generates Mocks & Fakes at compile-time.

Mocking applies to interfaces & abstract classes, which are mocked by implementing them
Faking applies to concrete trees, and to interfaces & abstract classes, which are faked by implementing them

A Mock is an object implementing an interface (or extending an abstract class) whose behaviour is configurable at run-time, usually specifically for unit-tests.
Mocks can be used to validate that a method or property was (or wasn’t) accessed in specific conditions.

A fake is an instance that contains bogus data: all nullables are null, all strings are empty, all numbers are 0.
A fake can be used when you need to instantiate a type to test an API but do not care about the data it contains.
An interface (or abstract class) is faked by a generated implementation: its functions do nothing, and its properties are themselves fakes.
