See theZTestWorkflowEnvironment companion object

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:

def awaitTermination(options: ZAwaitTerminationOptions): UIO[Unit]

Blocks until all tasks have completed execution after a shutdown request, or the timeout occurs, or the current thread is interrupted, whichever happens first.

def currentTimeMillis: UIO[ZCurrentTimeMillis]

This time might not be equal to java.lang.System.currentTimeMillis() due to time skipping.

This time might not be equal to java.lang.System.currentTimeMillis() due to time skipping.

Attributes

Returns

the current in-memory test Temporal service time in milliseconds or java.lang.System.currentTimeMillis() if an external service without time skipping support is used

def getDiagnostics: UIO[String]

Currently prints histories of all workflow instances stored in the service. This is useful information to print in the case of a unit test failure.

Attributes

Returns

the diagnostic data about the internal service state.

def namespace: String
def newWorker(taskQueue: String, options: ZWorkerOptions): UIO[ZWorker]

Creates a new Worker instance that is connected to the in-memory test Temporal service.

Creates a new Worker instance that is connected to the in-memory test Temporal service.

Value parameters

taskQueue

task queue to poll.

Attributes

def setup(options: ZAwaitTerminationOptions): URIO[Scope, Unit]

Setup test environment with a guaranteed finalization.

Setup test environment with a guaranteed finalization.

Value parameters

options

await options with polling interval and poll delay

Attributes

def shutdown: UIO[Unit]

Initiates an orderly shutdown in which polls are stopped and already received workflow and activity tasks are executed.

def shutdownNow: UIO[Unit]

Initiates an orderly shutdown in which polls are stopped and already received workflow and activity tasks are attempted to be stopped. This implementation cancels tasks via Thread.interrupt(), so any task that fails to respond to interrupts may never terminate.

def sleep(duration: Duration): UIO[Unit]

Wait until internal test Temporal service time passes the specified duration. This call also indicates that workflow time might jump forward (if none of the activities are running) up to the specified duration.

This method falls back to Thread.sleep if an external service without time skipping support is used
