After the pom is added, the CBA can be used in IntelliJ as a maven project.CBA as
Create a new empty project
Image Removed
You should now .png?version=1&modificationDate=1646749031000&cacheVersion=1&api=v2&height=400)
Image Added
Give it a name
.png?version=1&modificationDate=1646749073000&cacheVersion=1&api=v2&height=400)
Image Added
Click the + symbol and select import module
.png?version=1&modificationDate=1646749111000&cacheVersion=1&api=v2&height=400)
Image Added
Select the pom.xml in your CBA directory
.png?version=1&modificationDate=1646749178000&cacheVersion=1&api=v2&height=400)
Image Added
CBA with JSON & Templates
Inorder to Validate the Templates we require JSON file where we include variable values, so that it maps to the VTL
For each variable in base-config-template.vtl we have base-config-velocity.json which has variable values
.png?version=1&modificationDate=1646750279000&cacheVersion=1&api=v2&height=400)
Image Added
Similarly, we have default-variable-value-data.json which has only one variable value for default-variable-value-template.vtl
.png?version=1&modificationDate=1646750626000&cacheVersion=1&api=v2&height=400)
Image Added
You should now be able to write, run unit tests
.png?version=1&modificationDate=1646728020000&cacheVersion=1&api=v2&height=400)
Image Removed
Once we run the testsunit tests
Create BlueprintVelocityTemplateTest class , Under Test directory to implement unit tests
.png?version=1&modificationDate=1646751909000&cacheVersion=1&api=v2&height=400)
Image Added
Here we use the existing class BlueprintVelocityTemplateService whichis in CDS container by importing it to project ,where
it has Velocity Engine implementation
.png?version=1&modificationDate=1646752023000&cacheVersion=1&api=v2&height=400)
Image Added
You can implement following methods to test the templates
First we use assertNotNull() method means "passed parameter must not be null ": if it is null then the test case fails
.png?version=1&modificationDate=1646752944000&cacheVersion=1&api=v2&height=400)
Image Added
Second, assertEquals can be used to check if two objects is equally defined or not
.png?version=1&modificationDate=1646753047000&cacheVersion=1&api=v2&height=400)
Image Added
Third , we take the Expected value variable from a file
.png?version=1&modificationDate=1646753421000&cacheVersion=1&api=v2&height=400)
Image Added
Then we write tests
.png?version=1&modificationDate=1646753487000&cacheVersion=1&api=v2&height=400)
Image Added
Once you include Test code, Make sure your CBA is working properly, then run the below command in the terminal
.png?version=1&modificationDate=1646752276000&cacheVersion=1&api=v2&height=400)
Image Added
we get Build Success
.png?version=1&modificationDate=1646752467000&cacheVersion=1&api=v2&height=400)
Image Added
Then, Modify run configuration add Environmental variables
.png?version=1&modificationDate=1649647067000&cacheVersion=1&api=v2&height=400)
Image Added
Once you run the BlueprintVelocityTemplateTest class, then we get the result result
.png?version=1&modificationDate=1646728474000&cacheVersion=1&api=v2&width=768)
Image Removed.png?version=1&modificationDate=1646753704000&cacheVersion=1&api=v2&height=400)
