Overview

WorkManager Testing is a library for testing app code that runs using WorkManager.

This testing library provides a way to manually initialize WorkManager for tests by using WorkManagerTestInitHelper. Once initialized, you can use WorkManagerTestInitHelper to drive constraints and timing-related triggers for your background work.

For ease of testing, this library defaults to using a synchronous java.util.concurrent.Executor; you can change this in the Configuration if you wish.
