Philips Hue gets Groovy

My first Groovy script when figuring out how to use the Philips Hue lights.

Details on the Philips Hue Api can be found here.

import groovyx.net.http.*

@Grab(group='org.codehaus.groovy.modules.http-builder',

    module='http-builder', version='0.5.2' )


class HueLamp {
int id 

HueLamp(int id = 1) {
this.id = id
}

def status(boolean on, int hue) {
def base = "http://192.168.2.32/"
def api = "api/newdeveloper/lights/$id/state"
def url = base + api

def http = new HTTPBuilder( url)
http.request( Method.PUT, ContentType.JSON ) { req ->
           body = ["on" : on, "transitiontime" : 1,
                      "hue" : hue, "sat" : 255, "bri" : 255 ]
           response.success = { resp, json ->
println json
           }

           response.failure = { resp ->
println resp
           }
}
}
}

Details on how to use the Groovy Http builder are found here. 

The status method updates the lamp hue. Below an example of looping over different colors:

def hueMax = 65535

def stepSize = (int)hueMax/nrSteps

def hues = (0..25).collect{ it*stepSize }

def lamp = new HueLamp(1)

hues.each{ hue ->

lamp.status(true, hue)

Thread.sleep(100)

}

Interested an need more code? Check out this java/groovy project on Github from Stephan Jaetzold.

Enjoy. 

RoboLectric with Gradle and Android Studio

Below you will find a small log of trying to run Robolectric on Android studio using the gradle build.

Used sources:
[1] build.gradle file: http://stackoverflow.com/questions/16649397/robolectric-with-gradle-resources-not-found?rq=1
[2] Add jars to Android Studio: http://stackoverflow.com/questions/16881936/android-studio-missing-external-dependencies

Adapting the build.gradle file according to this link on stackoverflow. build.gradle:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.5.+'
    }
}

repositories {
    mavenCentral()
    maven {
        url 'https://oss.sonatype.org/content/repositories/snapshots/'
    }
}

apply plugin: 'android'

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 16
    }
}

sourceSets {
    testLocal {
        java.srcDir file('src/test/java')
        resources.srcDir file('src/test/resources')
    }
}

dependencies {
    compile 'org.roboguice:roboguice:2.0'
    compile 'com.google.android:support-v4:r6'


    testLocalCompile 'junit:junit:4.8.2'
    testLocalCompile 'org.robolectric:robolectric:2.1'
    testLocalCompile 'com.google.android:android:4.0.1.2'
    testLocalCompile 'com.google.android:support-v4:r6'
    testLocalCompile 'org.roboguice:roboguice:2.0'
}

task localTest(type: Test, dependsOn: assemble) {
    testClassesDir = sourceSets.testLocal.output.classesDir

    android.sourceSets.main.java.srcDirs.each { dir ->
        def buildDir = dir.getAbsolutePath().split('/')
        buildDir =  (buildDir[0..(buildDir.length - 4)] + ['build', 'classes', 'debug']).join('/')

        sourceSets.testLocal.compileClasspath += files(buildDir)
        sourceSets.testLocal.runtimeClasspath += files(buildDir)
    }

    classpath = sourceSets.testLocal.runtimeClasspath
}

check.dependsOn localTest

This results in a working build using this DummyTest class in src/test/java/...

package org.fhict.calculator.rtest;

import junit.framework.Assert;

import roboguice.test.RobolectricRoboTestRunner;

import org.junit.runners.Parameterized;
import org.junit.runners.Parameterized.Parameters;

import org.junit.runner.RunWith;
import org.junit.Before;
import org.junit.Test;

import org.robolectric.Robolectric;
import org.robolectric.RobolectricTestRunner;


@RunWith(RobolectricTestRunner.class)
public class DummyTest {

    @Before
    public void setUp() {
    }

    @Test
    public void testSomeNumber() {
        Assert.assertEquals(true,true);
    }

}

From command line a build is now running ('gradle localTest' from terminal). Generating a test-report in file:///home/ben/AndroidStudioProjects/CalculatorProject/Calculator/build/reports/tests/org.fhict.calculator.rtest.DummyTest.html

AndroidStudio does not yet recognize the new jar files as defined by testLocalCompile in build.gradle. Manually add them to AndroidStudio using this link.

Remaining open issues:

(1) How to show the output of the Robolectric unit tests in AndroidStudio?

(2) How to force recompile when the RoboLectric unit test has been changed? Now only a gradle clean && gradle localTest. Not so nice...

Please comment if you know how to solve these?
