Jme3-testable API

This is an initial implementation for the testable api, targeting issue jmonkeyengine#1649, which suggests building a better test chooser backend for jme3-examples, where one can pickup which test cases to run inside a package.

This is a video demonstrating testables in action:

F.A.Q:

How can I make my own test?: A: Your test should extends JmeTestApp or JmeTestState, in either cases, you will override launch() method and add what you want to test there, whether a JmeApplication.attachState(this); for AppStates or setting up AppSettings and start() or setting up a JmeSurfaceView for android.

Does this approach provide a recursive way of opening a package? A; Yep, all you need to do, is to give the package, which can be done by 2 methods : METHOD-A :

 TestableExecutor.getInstance().launch("jme3test", "--No-Data--", tags);

METHOD-B :

 TestableExecutor.getInstance().launch(Main.class.getPackage().getName(),
                                       "--No-Data--", tags);

Can I test multiple packages that aren't on the same tree, at the same time? A: Yep, just use :

TestableExecutor.getInstance().launch(new String[] {"jme3test.app", "jme3test.animation"},
                                     "--No-Data--", tags);

Can I use multiple tags in the same @TestableTags annoation? A: Yep, use this:

@TestableTags({Launcher.TAG_WATER_FILTERS, Launcher.TAG_ALL})

But, no @TestableTags repetition...it complicates simple stuff and not clean anyway.

What will happen if I have non-class files on my package A: Don't worry, the utility skips those.

What will happen if I have other classes not implementing the Testable? A: Those are skipped too.

Can I use this on android? A: Theoretically, you can, but I haven't found the time to test that yet.

What will happen if I extended JmeTestApp and didn't add a @TestableTags with a signature? A: The utility will exclude this test, because how should it know 'is it ready to be executed?', if you want to run all Testables under a package then use a unified tag in all those classes, for example, add this to all the testables you want to run Launcher.TAG_ALL while you can still use other tags to filter your tests for other run configurations:

@TestableTags({Launcher.TAG_WATER_FILTERS, Launcher.TAG_ALL})

I think that is it, for now, if that is what you are seeking, then i hope it will be helpful, please give a quick review.

Examples:

  1. The Testable class :
package jme3test.app.test;

import com.jme3.system.AppSettings;
import com.avrsandbox.jme3.testable.app.JmeAppTest;
import com.jme3.scene.Geometry;
import com.jme3.scene.shape.Box;
import com.avrsandbox.jme3.testable.TestableTags;
import jme3test.Launcher;

/**
 * Test a bare-bones application, without SimpleApplication.
 */
@TestableTags({Launcher.TAG_ALL})
public class BareBonesAppTest extends JmeAppTest<AppSettings> {

    private Geometry boxGeom;

    public static void main(String[] args){
        AppSettings settings = new AppSettings(true);
        settings.setRenderer(AppSettings.LWJGL_OPENGL2);
        settings.setAudioRenderer(AppSettings.LWJGL_OPENAL);
        new BareBonesAppTest().launch(settings);
    }


    @Override
    public void simpleUpdate(float tpf) {
        super.simpleUpdate(tpf);
        boxGeom.rotate(tpf * 2, tpf * 4, tpf * 3);
    }

    @Override
    public void simpleInitApp() {
        // create a box
        boxGeom = new Geometry("Box", new Box(2, 2, 2));

        // load some default material
        boxGeom.setMaterial(assetManager.loadMaterial("Interface/Logo/Logo.j3m"));

        // attach box to display in primary viewport
        rootNode.attachChild(boxGeom);
    }


    @Override
    public void launch(AppSettings userData) {
        super.launch(userData);
        setSettings(userData);
        setShowSettings(false);
        start();
    }
}
  1. The Launcher (main class) :
package jme3test;

import com.jme3.system.AppSettings;
import com.avrsandbox.testable.util.TestableExecutor;
import java.lang.reflect.InvocationTargetException;

/**
 * Tests the new jme test api.
 *
 * @author pavl_g.
 */
public class Launcher {
    public static final String TAG_ALL = "ALL";
    public static final String TAG_WATER_FILTERS = "WATER-FILTER";
    public static final String TAG_PBR = "PBR";

    public static final String[] tags = new String[] {
            TAG_ALL
    };

    public static void main(String[] args) throws InstantiationException, IllegalAccessException,
                                                  ClassNotFoundException, NoSuchMethodException,
                                                  InvocationTargetException {
        final AppSettings settings = new AppSettings(true);
        settings.setRenderer(AppSettings.LWJGL_OPENGL2);
        settings.setAudioRenderer(AppSettings.LWJGL_OPENAL);
        TestableExecutor.getInstance().launch(new String[] {"jme3test"}, settings, tags);
    }
}
