GIPS Tests

GIPS is an open-source framework for Graph-Based (M)ILP Problem Specification. This repository holds some GIPS test projects.

Setup

• Install GIPS as described in its repository.
• Launch a runtime workspace (while using a runtime Eclipse) as stated in the eMoflon::IBeX installation steps. (Please refer to the installation steps of GIPS above.)
• Clone this Git repository to your local machine and import it into Eclipse: File -> Import -> General -> Existing Projects into Workspace. Import all projects.
• Build all your projects with the black eMoflon hammer. Sometimes, it is required to trigger a cleaning in Eclipse (Project -> Clean... -> Clean all projects).

Requirements

Currently, all of the tests use the Gurobi (M)ILP solver, which is a commercial solution. Thus, you have to install and configure Gurobi or change the configuration of all tests in the GlobalTestConfig file from GUROBI to another solver.

Running all tests

The easiest way of running the whole test suite is by using one of the provided Eclipse launch files:

• test.suite.gips.launch - launches all JUnit tests without explicitly setting environment variables. This file fits the use case that you are using an Eclipse runtime workspace with properly set up environment variables in your runtime launch config.
• test.suite.gips.envs.launch - launches all JUnit tests with standard environment variable values. This file fits the use case that you did not set up proper environment variables in your Eclipse runtime workspace or you are using GIPS as a deployed plug-in.
