Represents ZTestEnvironment options.

TestWorkflowEnvironment provides workflow unit testing capabilities.

Testing the workflow code is hard as it might be potentially very long running. The included in-memory implementation of the Temporal service supports an automatic time skipping. Anytime a workflow under the test as well as the unit test code are waiting on a timer (or sleep) the internal service time is automatically advanced to the nearest time that unblocks one of the waiting threads. This way a workflow that runs in production for months is unit tested in milliseconds. Here is an example of a test that executes in a few milliseconds instead of over two hours that are needed for the workflow to complete:

Expose methods to read and deserialize workflow execution history from json.

NOTE from Java SDK: 2021-11-29 Experimental because the user facing interface to history replay functionality is actively evolving.

Replays a workflow given its history. Useful for backwards compatibility testing.
