Hi,  
I was able to resolve the issue following this

> [@Issues with Unit Testing a Workflow with signal method](https://community.temporal.io/t/issues-with-unit-testing-a-workflow-with-signal-method/1735):
>
> Hello I am using java temporal-sdk v1.0.6. I am trying to test a Workflow with signal method using mocks for Activity. Sample code is here [Comparing temporalio:master...ansujohn:SignalWF\_Test · temporalio/samples-java · GitHub](https://github.com/temporalio/samples-java/compare/master...ansujohn:SignalWF_Test?expand=1) Couple of issues that i get in [samples-java/HelloSignalWorkflowTest.java at SignalWF\_Test · ansujohn/samples-java · GitHub](https://github.com/ansujohn/samples-java/blob/SignalWF_Test/src/test/java/io/temporal/samples/helloSignal/HelloSignalWorkflowTest.java#L19) Test failing with error “Actually, there were zero interactions with this mock” Though signalChange method is called twice, processing is done …

I have a follow up query. Can we retry a signal just like activities?
