Gradle Wrapper and proxy issues

I wanted to use the Gradle Wrapper, but wanted to keep the download internal to avoid having to expose proxy setting in the gradlew scripts.

The change was quite simple. We hosted the files on a staging server (Windows) and simply changed the gradle-wrapper.properties to the following:

	distributionBase=GRADLE_USER_HOME
	distributionPath=wrapper/dists
	zipStoreBase=GRADLE_USER_HOME
	zipStorePath=wrapper/dists
	distributionUrl=file:////SERVER/some/path/gradle/distributions/gradle-1.7-bin.zip

Gradle task rule for Selenium testing

I've been working quite closely with one of the testers who's written a test suite using Selenium. He had initially wrote a single gradle task for each browser.

As i hope you can see its a little clunky:

	task intTestFirefox(type: Test) {
	maxParallelForks = 2
	systemProperties['LOCAL_DRIVER'] = false
	systemProperties['REMOTE_DRIVER'] = true
	systemProperties['SAUCE_DRIVER'] = false
	systemProperties['GRID_HOST'] = 'localhost'
	systemProperties['GRID_PORT'] = '4444'
	systemProperties['BROWSER'] = 'firefox'
	systemProperties['PLATFORM'] = 'WINDOWS'
	systemProperties['BASE_TEST_RESULTS_PATH'] = "$buildDir/Screenshots/$version"
	systemProperties['APPLICATION_URL'] = 'http://someurl'
	testClassesDir = sourceSets.inttest.output.classesDir
	classpath = sourceSets.inttest.runtimeClasspath
	useTestNG()
	}
	task intTestChrome(type: Test) {
	maxParallelForks = 2
	systemProperties['LOCAL_DRIVER'] = false
	systemProperties['REMOTE_DRIVER'] = true
	systemProperties['SAUCE_DRIVER'] = false
	systemProperties['GRID_HOST'] = 'localhost'
	systemProperties['GRID_PORT'] = '4444'
	systemProperties['BROWSER'] = 'chrome'
	systemProperties['webdriver.chrome.driver'] = 'C:/Automation/lib/chromedriver.exe'
	systemProperties['PLATFORM'] = 'WINDOWS'
	systemProperties['BASE_TEST_RESULTS_PATH'] = "$buildDir/Screenshots/$version"
	systemProperties['APPLICATION_URL'] = 'http://someurl'
	testClassesDir = sourceSets.inttest.output.classesDir
	classpath = sourceSets.inttest.runtimeClasspath
	useTestNG()
	}

So, I set out to make this more flexible and minimize the amount of code in the build file. Using rules which are provided by the Gradle API I was able to write the following task:

	tasks.addRule('Rule Usage: intTest<Browser>') { String taskName ->
	if(taskName.startsWith('intTest')) {
	task(taskName, type: Test) {
	ext.browser = taskName - 'intTest'
	systemProperties['LOCAL_DRIVER'] = false
	systemProperties['REMOTE_DRIVER'] = true
	systemProperties['SAUCE_DRIVER'] = false
	systemProperties['BROWSER'] = ext.browser
	systemProperties['GRID_HOST'] = 'localhost'
	systemProperties['GRID_PORT'] = '4444'
	systemProperties['PLATFORM'] = 'WINDOWS'
	systemProperties['BASE_TEST_RESULTS_PATH'] = "$buildDir/Screenshots/$version"
	systemProperties['APPLICATION_URL'] = 'http://someurl'
	maxParallelForks = 2
	testClassesDir = sourceSets.inttest.output.classesDir
	classpath = sourceSets.inttest.runtimeClasspath
	useTestNG()
	}
	}
	}

Now all thats required is "gradle intTestChrome" or "gradle intTestFirefox".... perfect!

Gradle Logging - writing to a log to file

This simple Gist adds 2 additional output listeners; Standard Out and Standard Error and pipes their output to a build log.

	def tstamp = new Date().format('yyyy-MM-dd_HH-mm-ss')
	def buildLogDir = "${rootDir}/build/logs"
	mkdir("${buildLogDir}")
	def buildLog = new File("${buildLogDir}/${tstamp}_buildLog.log")
	import org.gradle.logging.internal.*
	System.setProperty('org.gradle.color.error', 'RED')
	gradle.services.get(LoggingOutputInternal).addStandardOutputListener (new StandardOutputListener () {
	void onOutput(CharSequence output) {
	buildLog << output
	}
	})
	gradle.services.get(LoggingOutputInternal).addStandardErrorListener (new StandardOutputListener () {
	void onOutput(CharSequence output) {
	buildLog << output
	}
	})
