WorkManagerTestInitHelper

public static void closeWorkDatabase()

Closes internal androidx.work.WorkManager's database.

It could be helpful to avoid warnings by CloseGuard in testing infra. You need to be make sure that WorkManager finished all operations and won't touch database anymore. Meaning that both getTaskExecutor and getExecutor are idle.

It shouldn't be called from getTaskExecutor because this method will block until all internal work is complete after cancellation. To complete this work getTaskExecutor could be require and blocking it may lead to deadlocks.
