Technical notes about the configuration of Hudson (for developers).

Writing tests during model development is a good practice:

1. It ensures that code modification do not modify the coherence of the expected results.
2. It validates the model on particular cases.

Tests are written with JUnit4 : https://www.junit.org/

All the tests are stored in a particular package hierarchy in the directory:

test/src

Tests can be written in Java or Groovy.

test/src/maddmodule/MaddModuleScriptTest.java

package maddmodule.model;
 
import static org.junit.Assert.assertTrue;
import maddmodule.script.MaddEvolutionParameters;
import maddmodule.script.MaddInitialParameters;
 
import org.junit.Test;
 
import capsis.kernel.Step;
import capsis.script.C4Script;
 
public class MaddModuleScriptTest {
 
    @Test
    public void testC4Script() throws Throwable {
 
	// init
        C4Script s = new C4Script("maddmodule");
        MaddInitialParameters i = new MaddInitialParameters (s.getModel(), 
							     s.getDataDir() + "/maddmodel/A.inv");
        s.init(i);
        int nbTree = ((MaddStand)(i.getInitStand())).getTrees().size();
 
        // evolution
        Step result = s.evolve(new MaddEvolutionParameters (200));
 
        // nb of trees is growing
        assertTrue(result != null); 
        assertTrue( nbTree < ((MaddStand)(result.getStand())).getTrees().size());;
    }  
}

test/src/test/test.groovy

package test
 
import org.junit.Test
import static org.junit.Assert.assertEquals
 
class ArithmeticTest {
    @Test
    void additionIsWorking() {
        assertEquals 4, 2+2
    }
 
    @Test(expected=ArithmeticException)
    void divideByZero() {
        println 1/0
    }
}

You may use the assertion methods in the doc below in your test methods to check for expected values for some interesting variables.

To compile all the tests, type from the Capsis install directory:

On Linux/macOS:

sh ant compile-test

On Windows:

ant compile-test

To run all the tests, type from the Capsis install directory:

On Linux/macOS:

sh ant test

On Windows:

To run a particular test, type from the Capsis install directory:

On Linux/macOS:

sh ant run-test -Dtest=Full/TestName

# e.g. for douglas.DouglasTest in test/src/
sh ant run-test -Dtest=douglas/DouglasTest

On Windows:

ant run-test -Dtest=Full/TestName

# e.g. for douglas.DouglasTest in test\src\
ant run-test -Dtest=douglas/DouglasTest
