When working on a task with parameters, we suggest you use mock parameters first for testing before using the actual parameters. Using mock parameters will be easier for you and save time while writing and testing the task. Because the actual parameter that will be used later maybe contain large values such as a hundred list of data from Excel or CSV. So, you can just create the mock parameter and fill it in a few numbers of the data or values that represent the actual data. By doing this, you won't be overwhelmed by the long parameter values to be loaded and checked while testing.
