#MunitTools::notNullValue()0 discussing

I am writing MUnit for a flow like below

My Munit looks like

But when try to run i ma getting an exception like below . The XML in exception is the sample response given as thre payload value in mock response.

Let's say i have munit

	</munit:test>

but got empty string '' value when enter to testing flow. What am I doing wrong?

I have a flow that has the Salesforce create connector, the Munit test that references the flow Runs fine locally. But when I try to deploy them to the CloudHub using the Azure Devops CI/CD pipeline throws error like

WARN 2022-04-07 23:41:54,103 [[MuleRuntime].uber.04: [mule-salesforce-sys].salesforce-Opportunity-create-flow/processors/3.ps.BLOCKING @3c7baec] org.mule.extension.salesforce.internal.connection.provider.BasicConnectionProvider: Couldn't obtain access token because an exception has occurred. Runtime to handle the ConnectionException. Root exception was: Invalid status code: 400, response body: {"error":"invalid_client","error_description":"invalid client credentials"}

.

org.mule.runtime.extension.api.exception.ModuleException: Invalid status code: 400, response body: {"error":"invalid_client","error_description":"invalid client credentials"}

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Invalid status code: 400, response body: {"error":"invalid_client","error_description":"invalid client credentials"}

But before I created the Munit tests I deployed the flow to the CloudHub and there was no issues or error. I can still access the endpoint. After adding the Munit tests and deploying it throws error. All the credentials are stored in the Pipeline Variables..

And the Munit test

I have a customer assertion class which is located under src/test/java or /src/test/munit either 

If I run the munit, I get  

java.lang.ClassNotFoundException: com.example.CustomAssertion

the definition of the customer assertion is taken from the documentation 

https://docs.mulesoft.com/munit/2.1/run-custom-event-processor

the munit test file

 <munit:validation >

<munit-tools:assert-that doc:name="Assert the return of MessageID " doc:id="61e7edf9-fa90-4228-8794-5ff31c20cc6c" expression="#payload" is="#MunitTools::notNullValue()" message="MessageID should not be null or empty"/>

<!-- customer assertion -->

<munit-tools:run-custom assertion="com.example.CustomAssertion" expression="#payload" />

</munit:validation>

The documentation does not state any additional details.

Any idea why this class is not found even it is on the test class path
