Setting Headers and UriParams in MUnit test case in Mule 4 Set Event Processor can be used to pass headers before calling any sub-flow in MUnit test flow.  Uri Parameters also can be set in the same way. Headers < munit:set-event doc:name = "Set Event" doc:id = "70453df1-e368-488b-abcc-f8522185dd4f" >        < munit:payload value = " #[''] " encoding = "UTF-16" />        < munit:attributes value = " #[{headers : {' token ' :' b536b9a9-5e11-4773-93d3-8c973519ad54 ' , ' role ' :' Administrator,User '}}] " encoding = "UTF-16" /> </ munit:set-event >   UriParams < munit:set-event doc:name = "Set Event" doc:id = "70453df1-e368-488b-abcc-f8522185dd4f" >        < munit:payload value = " #[''] " encoding = "UTF-16" />        < munit:attributes...

Creating a test case with mocking of SOAP web service call using MUnit 2.1.3 in Mulesoft Transform processor will not work if you are just providing the original response of SOAP service as mock response. So you need to you tweak little in order to make it work with Transform message processor. Look at the following example.  The is the complete SOAP message taken from the original response. <? xml version = '1.0' encoding = 'windows-1252' ?> < body > < env:Envelope xmlns:env = " http://schemas.xmlsoap.org/soap/envelope/ " >    < env:Header />    < env:Body >       < m:getTokenWSResponse xmlns:m = " http://example.net/example-services " >          < m:SessionResponse >             < com:RequestStatus xmlns:com = " http://example.net/security/common " > 0 </ com:R...

MUnit Matchers MUnit matchers are a set of DataWeave functions to define assertion conditions in terms of general values instead of specific hardcoded values . When defining matchers you need to add the  MunitTools::  prefix to the expression. Matchers are grouped according to the type of conditions you want to validate. You can find: Core Matchers These matchers evaluate core values in the expression. You can use these matchers to evaluate: o    Whether the expression is null or not. o    Media Type or Encoding of the expression. o    Whether the returns false. o    Whether two evaluations were successful. These matchers are: Matcher Description Example nullValue() Checks that the expression is null. o    #[MunitTools::nullValue()] notNullValue() Checks that the expression is not null. o    #[MunitTools::notNullValue(...
