This page describes one of the test cases of the EODiSP. The test case described in this page instantiates a nominal scenario of the use case UC_302.

This test case describes the steps required to generate an HLA wrapper for an excel-based model. The test case assumes that the excel-based model is identical to the Sim_Controller model of the EarthCARE Simulator with one difference: The target excel-based model has one additional output parameter called offset.

Overview

Identifier	TC_302
Name	Generate Wrapper Code for an Excel Workbook
Primary Actor	ETH_2 Model Owner
Description	Describes the steps required to change the existing sim_controller federate. This is the federate that wraps an Excel Workbook. The change to be performed is to add an offset parameter to the orbit_propagator.
Pre-Condition	(1) The SOM for the sim_controller must be available. (2) The Java template class file for the sim_controller federate is available. (3) The Excel Workbook is available. (4) Microsoft Excel is installed on the model owner's computer.
Post-Condition	A sim_controller federate with the additional offset parameter added. This federate could be integrated into the EarthCARE simulator.

Steps

1. Actor adds the offset attribute to the sim_controller SOM file.
2. Actor runs the HLA Wrapper Generator Application to create the HLA wrapper skeleton (see test case TC_320).
3. System generates the Java classes.
4. Actor adds the offset parameter to the appropriate Excel Worksheet and associates a name to it.
5. Actor uses the Excel Wrapper Generator to generate the Java classes for the changed sim_controller Workbook.
6. System generates the Java classes.
7. Actor opens the Excel wrapper template file provided by the EODiSP. The template file is a Java class with comments. These comments are self-explanatory and show the actor where to insert custom code.
