Hi, I think I’m using OnWorkflow incorrectly. Could someone enlighten me please? Thanks! func SimpleWorkflow(ctx workflow.Context, u []uuid.UUID) error { if workflow.GetInfo(ctx).ContinuedExecutionRunID == "" { if err := workflow.ExecuteActivity(workflow.WithActivityOptions(ctx, workflow.Acti…

Doesn’t that mean that the parent workflow will wait until the child workflow is completed? Not sure I understand the question exactly. Basically if you call “Future.Get()” in a workflow, it waits for “Get()” to complete. If that “Get()” is on a child future, it will wait for the child workflow t…

Imo you just do not need to register SimpleChildWorkflow in the test. Though I did not try this in action :slightly_smiling_face:

Mmm, when that line is removed, the code panics with: unable to find workflow type: SimpleChildWorkflow. Supported types: [SimpleWorkflow]

Use it like this: env.OnWorkflow("SimpleChildWorkflow", .... It is testyfy-like, so… It seems that all those things you register before are things that will be used in a test as real implementations.

The code still panics. //env.RegisterWorkflow(SimpleChildWorkflow) env.OnWorkflow("SimpleChildWorkflow", mock.Anything, mock.Anything).Return( panic: unable to find workflow type: SimpleChildWorkflow. Supported types: [SimpleWorkflow]

You never wait on a child workflow, so the workflow just completes immediately. You should at least confirm the child workflow got started without error much less actually runs without error. Something like this: func SimpleWorkflow(ctx workflow.Context, u []uuid.UUID) error { if workflow.GetInfo(…

Silly question, is there a way to wait until the child workflow starts? I don’t want to block until all the children workflow have completed.

Absolutely, see workflow package - go.temporal.io/sdk/workflow - Go Packages . Specifically the future has a getter for a “start” future on it that returns the execution if err := future.GetChildWorkflowExecution().Get(ctx, nil); err != nil { // Problem starting workflow. return err }

Perhaps I’m not reading the documentation correctly. The Get() method will block until the workflow completes and results are available. from: workflow package - go.temporal.io/sdk/workflow - Go Packages Doesn’t that mean that the parent workflow will wait until the child workflow is completed? I…

Just to add, this forum post has good info on starting child async.
