Munit: Automate Munit Test Case Creation Using API Specification
After Reading this blog you will be able to,
. Create MUnit test cases,
. Designing and Creating MUnit test cases using RAML API specification,
. Modify and Run autogenerated MUnit test cases and build the Coverage report.
Why MUnit?
MUnit is a MuleSoft feature that helps developers to build automated test cases for their Mule applications.
MUnit version 2.3 works for all the Mule 4 versions. MUnit is fully integrated with Anypoint Studio, allowing us to design, develop and run MUnit tests.
Scaffold MUnit test cases from an API specification
MUnit test cases play vital role in API life cycle. However, writing MUnit test cases takes considerable amount of time. In future whenever mule flows are updated, MUnit test cases also must be updated.
Fortunately we can save some of this time by making use of autogenerated MUnit test cases by API specifications.
However, developers can also use MuleSoft’s MUnit test recorder to fully automate the MUnit test case creation. Click here to know more about Munit test recorder.
In this blog we will learn simple steps to create and execute MUnit Test cases using API specs.
Step 1. Create a simple API specification that accepts sample json input and returns a json payload as an output as shown below.
Step 2. Import API specification from Design Center to Anypoint Studio to generate the flows through APIkit Router.
Step 3. Right click on the APIkit Router and select Create Test Suite for <yourapplicationname.xml> from API Specification.
observe the auto generated MUnit test cases and sample request and response payloads under src/test/resources folder.
Step 4. Make some important(but not necessary) changes to MUnit flow such as,
- Drag the set payload component from Behavior section to Execution section.
- Increase response timeout of HTTP Requester connector to avoide the time out issue.
- You can also make use of readUrl expression to read the sample payload files from src/test/resources.
Step 5. Right click on the flow and run MUnit test suite. You will observe that the MUnit test getting executed successfully.
