Types

type WorkflowTester

type WorkflowTester[TResult any] interface {
	// Now returns the current time of the simulated clock in the tester.
	Now() time.Time

	// Execute executes the workflow under test with the given inputs.
	Execute(ctx context.Context, args ...interface{})

	// Registry returns the registry used by the tester.
	Registry() *registry.Registry

	// OnActivity registers a mock activity.
	OnActivity(activity workflow.Activity, args ...interface{}) *mock.Call

	// OnActivityByName registers a mock activity with the given name.
	OnActivityByName(name string, activity workflow.Activity, args ...interface{}) *mock.Call

	// OnSubworkflow registers a mock sub-workflow.
	OnSubWorkflow(workflow workflow.Workflow, args ...interface{}) *mock.Call

	// OnSubWorkflowByName registers a mock sub-workflow with the given name.
	OnSubWorkflowByName(name string, workflow workflow.Workflow, args ...interface{}) *mock.Call

	// SignalWorkflow signals the workflow under test with the given signal name and value.
	SignalWorkflow(signalName string, value interface{})

	// SignalWorkflowInstance signals the given workflow instance with the given signal name and value.
	SignalWorkflowInstance(wfi *core.WorkflowInstance, signalName string, value interface{}) error

	// WorkflowFinished returns true if the workflow under test is finished.
	WorkflowFinished() bool

	// WorkflowResult returns the result of the workflow under test. If the workflow is not finished yet, this will
	// error.
	WorkflowResult() (TResult, error)

	// AssertExpectations asserts any assertions set up for mock activities and sub-workflow
	AssertExpectations(t *testing.T)

	// ScheduleCallback schedules the given callback after the given delay in workflow time (not wall clock).
	ScheduleCallback(delay time.Duration, callback func())

	// ListenSubWorkflow registers a listener that is called whenever a sub-workflow is started. The listener is called
	// with the workflow instance of the sub-workflow and the name of the sub-workflow.
	ListenSubWorkflow(listener func(instance *core.WorkflowInstance, name string))
