Show HN: FaKeTime – A Kotlin library for easy fake time control in tests

2 points

10 months ago

I created faKeTime, a small Kotlin library to make testing time-dependent code easier and more reliable.

Time-dependent tests often cause flaky failures. With faKeTime, you can:

Freeze time at a fixed instant (FakeDateTime.fixed(...))

Auto-advance time on each call (coming soon)

Manually adjust time (coming soon)

Currently JVM-only. Kotlin Multiplatform support is in the works.

I’m happy to hear feedback or contributions.
