Mule requester in a MUnit Test case


I have to use a Mule Requester Inside MUnit test case to read a file under src/test/resources so that i can assert the payload . With the current implementation I have Ftp connector inside MUnits xml which I am referring from mule requester . I clearly see that mule requester is trying to access the connector even before it it initialized . Is there any way i can tell mule to early intialize ftp connector ?

Exception :

    ********************************************************************************
 Message               : Cannot perform an action on a connector when it is not started. Connector "no-delete-file-connector-test" is currently in lifecycle phase "initialise"

Following is my configuration :

<flow-ref name="processMainFlow" doc:name="processMainFlow" />
  <mulerequester:request resource="file://src/test/resources/expected-discrete.csv?connector=no-delete-file-connector-test" doc:name="Mule Requester" returnClass="java.lang.String"/>
<munit:assert-payload-equals expectedValue="#[flowVars.outputCSV]" doc:name="Assert Payload"/>
 <logger message="response for test #[payload] actual data : #[flowVars.outputCSV]" level="INFO"
     doc:name="Logger" />

Solution

  • To load a file in your Munit test, you don't need the file connector, use a Set Payload or Set Message, eg:

    <set-payload value="#[getResource('expected-discrete.csv').asStream()]" doc:name="Set Payload"/>
    

    The path inside getResource is relative to testResources specified in your pom file (defaults to src/test/munit and src/test/resources).

    The file connector is stopped because that is the default behaviour of connectors in Munit tests. There is more info about this in the Mulesoft forums: https://forums.mulesoft.com/questions/44649/munit-config-mock-inbounds-mock-connectors.html
