Munit parameterization in Mule 4

In this tutorial we will demonstrate how can we use munit parameterization in mule 4 to run the single test case for multiple input and output

To demonstrate we will create a sample mule application and create a munit suite to test the mule application

Sample application:

Here we will create 2 scenarios when the age is greater than and equal to 18 and less than 18, we will create a single test case and configure the 2 different scenarios and run the munit

To create the test case-> right click on the flow and create a blank munit test case for this flow as shown below

Blank test case is created

Create the input and output(expected result) under test folder

To configure the scenarios, go to testcase-> go to global elements->click on edit->

Click on + sign to add the parameterization, provide the name as adult-flow, now select the flow and add the input and output

Now add another scenario as a new parameter and follow the same process

Now set the input as set payload as shown below in munit

Configure the assert as shown below

Now run the munit, you can see both the test cases are passed and both the condition are tested and coverage is 100 %.
