This speeds up the development process for applications, compared to Mule 3. Does anyone have an idea about how a response payload from a cache-scoped request should be mocked in a way that does not affect all the test suite? MUnit is an integrated feature with Anypoint Studio and supports dependency tools like Maven. If set true, then it clones the event produced by the code and by default this property is false. For example, to assert that a payload is equal to a certain value, you can configure the Assert-That processor using the equalTo() matcher. In Mule 3 there was an option to set properties using mock:invocation-property but . While mocking HTTP-requester components in the MUnit test case, we need to configure the then-return element of the mocking component and refer downstream-flow to throw HTTP errors with the support of mule flow to produce HTTP error codes scenarios and asserts payload which will be assigned in the on-error scope of integration flow. Once the MUnit suite is triggered, then it will provide details such as errors, failures (if any), coverage report, and test status. Logging using Elastic Cloud for MuleSoft using HTTP Appender, CICD Implementation in Standalone Server using Jenkins [POC]. You can use either a then-return to return a static, constant value, or you can use a then-call to invoke a flow for cases where you might want the returned value to change over time, or to have different responses according to certain inputs. rev2023.3.3.43278.

So im guessing the tests are failing because the previous value is cached. How to tell which packages are held back due to phased updates. It will raise errors and use variables that are assigned in the set-event from the YAML configuration file to transform the expected payload in the HTTP error scenario. Assert that the returned payload is the one you set inside the On-error scope. As MUnit facilitates and supports parameterized files as input for trigger events for MUnit test cases based on parameters configured in a configuration file.
