Hi, for testing is there anyway to make my unit tests work if I use

Dispatchers.Main

dispatcher, or do I need to mock that guy? I'm getting

java.lang.IllegalStateException: Module with the Main dispatcher had failed to initialize

Hi @julioyg, you need to provide an implementation. I made an example in this PR: https://github.com/Kotlin/kotlinx.coroutines/pull/760/files Look for the

build.gradle

file,

TesMainDispatcher

, the

test/resources/META-INF/services/kotlinx.coroutines.internal.MainDispatcherFactory

file and the

LifecycleTest

file using it.

hey @louiscad I see the TestDispatcher, but I fail to see how to use it, and where to tell your tests to use it

It's automatically added via

ServiceLoader

with the resource in META-INF

ok... so I just copy that file under the same directory? sorry if it's a stupid question..

It works because it's integrated into the resources sourceSets from

build.gradle

, or is in a default resources directory
