Some of the Markup testcases are designed with different input parameters e.g. hashConfiguration, outputFields. In order to generate Markup testcases with these input parameters you need to use a template file. The testcase which use a template file will have a *.yaml file within the testcase directory.
In order to run testcase generation which utilises the template file you need to add the -Dtask.template=filename.yaml variable to the command when running the worker testing application.
