I'm getting this error while running junit test in android module
Exception in thread "main" java.lang.IllegalStateException: Module with the Main dispatcher had failed to initialize. For tests Dispatchers.setMain from kotlinx-coroutines-test module can be used
Does anyone know Dispatchers.setMain with what parameter should be called?

[Allan Wang]

Did you import an appropriate dependency to set your main dispatcher?

[Allan Wang]

See

https://github.com/Kotlin/kotlinx.coroutines/blob/master/ui/coroutines-guide-ui.md

Otherwise you need the test dependency to set your own main dispatcher

[Saiedmomen]

the one mentioned in the message of exception? yes#

[Saiedmomen]

I just don't know what to pass into setMain

[Allan Wang]

Are you not using android, swing, or javafx? Do you actually need a main dispatcher?

[Allan Wang]

You can find examples here

https://github.com/Kotlin/kotlinx.coroutines/blob/master/core/kotlinx-coroutines-test/README.md

[Saiedmomen]

yes. android. It is working on main source set. It is throwing this in junit test

[Saiedmomen]

Thank you but I'm still getting the same exception

[Allan Wang]

Can you post your unit test?

[Saiedmomen]
