MocKMP

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

  • Mocking only applies to interfaces

  • Faking only applies to concrete trees

A Mock is an object implementing an interface 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 a concrete class 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 class to test an API but do not care about the data it contains.
