For those DAO, Services, how about using static objects with mockk for test
The official suggests using dagger/hilt to inject them. However, they could be static based on the static ApplicationContext. Although Dagger/hilt aids in unit testing, mockk can accomplish this easily as well by modifying bytecode during run time. As for the stability, `mockk` has 5000+ stars on GitHub and keeps renewing.

Best practices for Unit Testing Android Apps with Mockk, Kotest and others
Mockk is a rather new framework; it was originally designed for Kotlin, although it supports Java as well. Before mockito-kotlin was released, using Mockk was much easier and beneficial for Kotlin developers, but right now both these frameworks have nearly the same set of features and similar syntax. For example, assume that our function loadUsers is no longer synchronous, but rather suspended:
-
LocalDateTime.now() mockk
You can use mockkStatic for that, see docs. Also don't forget to unmockkStatic afterwards.

reflective-mockk: Stub methods programmatically using kotlin-reflect
WARNING: reflective-mockk is currently powered by a reflective “hack” on mockK, and is thereby subject to removal/breakage by the mockK team at any time. If you enjoy this library & want it to be officially supported, post a comment saying so on this PR: https://github.com/mockk/mockk/pull/1005.

mockk VS mockative - a user suggested alternative

Spring with java vs Spring with kotlin
https://mockk.io/ is great, too.

From Java to Kotlin. There and back again
Mockito does not work correctly with Kotlin types out of the box. Spring recommends using Mockk. There is also a special module for Mockito, which adds support for Kotlin - Mockito-Kotlin.

Jackson, moshi or kotlinx.serialization?
strictNullCheck option in the Kotlin module doesn't cover non-object-field situations at all. https://github.com/FasterXML/jackson-module-kotlin/issues/479

Strings, Please! Eliminating Data Leaks Caused by Kotlin Assertions
But, it sucked. I was constantly finding bugs related to nullability, around generics, inline/value classes, etc. And it wasn't the typical trivial ones, either. Figuring out that you're calling a Java library and encountering a "platform type" is the least problematic. My biggest struggle came from using libraries that were written in Java first, but then added a Kotlin API on top. So, my code didn't know I was dealing with a platform type and neither did I. Yet they were still broken. Some of them are broken in an unfixable way, such as JacksonXML's Kotlin module: https://github.com/FasterXML/jackson-module-kotlin/issues/479. So many Java libraries rely on reflection even when it's not obvious that they might, so you pretty much can't ever use value classes in Kotlin, including the unsigned number types.

You should add Jackson Module Kotlin in your project. After that, you can't specify a type of object explicitly.

How Cloudflare security responded to log4j2 vulnerability
Not really, you just need to handle some standard types and have a good extension mechanism to let the user implement factories. That library having built in support for UUID and datetime is probably a bit much, I'd prefer a plugin like https://github.com/FasterXML/jackson-module-kotlin

Ktor vs Spring for creating an API
There is a bug at this very moment that makes it literally impossible to deserialize [1, 2, 3, null] into a List with Jackson's Kotlin module. Yes- even if you set KotlinModule(strictNullChecks = true). It's just broken. (Here's the link: https://github.com/FasterXML/jackson-module-kotlin/issues/479)

Kotlin Team AMA #3: Ask Us Anything
Got you, thanks. I didn’t mean to sound offensive - a better wording would be that they don’t seem to prioritize this part, at least based on https://github.com/FasterXML/jackson-module-kotlin/issues/199, which has one abandoned branch from a 3rd party and a couple of comments from from maintainers.
