Mocking Multiple connectors in the flow

Question

I have a flow where I have a connector to query and connector create record in Salesforce. I am a newbie to Mulesoft and the Munit tests. I just created a simple Munit tests for the flow with one connector to Salesforce. Just trying to do the same but running in to issue with the Munit tests with two mock

Flow with two Salesforce connectors

And the Munit Test is like below

        </munit:validation>
    </munit:test>

It thows error saying

org.mule.runtime.api.el.ExpressionExecutionException: You called the function 'Value Selector' with these arguments: 
  1: String ("Q138446")
  2: Name ("Id")

But it expects one of these combinations:
  (Array, Name)
  (Array, String)
  (Date, Name)
  (DateTime, Name)
  (LocalDateTime, Name)
  (LocalTime, Name)
  (Object, Name)
  (Object, String)
  (Period, Name)
  (Time, Name)

4| if(payload[0].Id != null)
      ^^^^^^^^^^^^^
Trace:
  at anonymous::main (line: 4, column: 4)

The transform before the create connector is erroring. How can I set the payload there and mock the create connector in my flow. Any help is greatly appreciated

Answer 1

It appears you are setting the condition for the mock but didn't actually set a value to replace the execution.

See this example from the documentation:

<munit-tools:mock-when processor="http:request">
   <munit-tools:with-attributes>
       <munit-tools:with-attribute attributeName="method" whereValue="#['POST']"/>
   </munit-tools:with-attributes>
   <munit-tools:then-return>
       <munit-tools:payload value="#['mockPayload']"/>
   </munit-tools:then-return>
</munit-tools:mock-when>

Notice that after <munit-tools:with-attributes> there is a <munit-tools:then-return> element that sets the mock payload.

Read the documentation link above to understand how to use mock and the various options it has.
