Mock component in munit
Download as PPTX, PDF0 likes587 views
The Mock component in MUnit allows you to define mocked behavior for a message processor. You can modify how a specific message processor responds when called with particular attributes. The example shows using Mock to replace the "Set Payload" processor with one that returns "Good Morning!" instead of "Hi", and asserting the payload is now "Good Morning!".

Mock component in munit
- 1. How to use Mock component in MUnit 04-04-2017
- 2. Abstract • The Mock feature provided by MUnit allows you to define mocked behavior for a message processor. In this case, MUnit replaces the normal behavior of the message processor with the behavior you define. Thus you can modify how a specific message processor responds when it is called with a particular set of attributes.
