Getting started with the MUnit Test Recorder | MuleSoft Below flow will receive an event triggered from flow test-mock-http-call-downstream-error and raise an error by Raise Error component and transform payload as expected for http error within On error continue component. I have create two test flows for subflow, which is working fine. View the coverage report to find out the test result report. The set-event has the cloneOriginalEvent property. If the database in this application and the connector used in the message processor are not ready to accept any request, we still we want to test it. I am trying to create MUnit for the below flow. This attribute is optional. <munit-tools:mock-when doc:name="Mock When" doc:id="5d-1aa . Then it will automatically generate a MUnit configuration file with the MUnit Scalitone.

After the test connection is successful press OK. Now we have to give the query as shown below: And after that we have to add a transform message to make the payload to json and then add a logger as shown below in the image: And after that we will have to deploy the project and once the project is deployed, we will send the request in Advanced REST Client and will check the response as shown below: After getting the200OK status we can check the response. MUnit coverage is based on the volume of MUnit message processors executed. Asking for help, clarification, or responding to other answers.

python_Python_Unit Testing_Mocking - For example: Given this flow, setup a named object store and caching strategy that uses said object store: Then is your tests, setup a before action to clear that store: Where as, without the os:clear it would only miss the cache first time, and print out the same payload from the cache: Or alternatively, you could move the cache and http processors to their own flow and mock the flow instead so cache is never used in your tests.

Suppose you have a processor inside a foreach scope and you want to provide different values on each iteration: Use an munit-tools:mock-when processor to mock the processor in your flow and use the then-call operation to call a new flow that set payloads depending on the foreach status: Inside the flow that is called by the then-call you can use a Choice processor to evaluate a value and set a mocked payload. Understanding MUnit Test In MuleSoft Mule 4. For mocking of the database we passed one dummy database payload in value as MunitTools::getResourceAsString('sample_payloads/database_payload.json'\), inside the folder location where it will compare with the actual database payload.
