colored log(back) for unit tests in two steps




The goal

Make my own stuff yellow, and keep the other stuff grey.

1. src/test/resources/logback.groovy
(modify the namespace you wanna highlight as your own)

	import ch.qos.logback.classic.boolex.GEventEvaluator
	import ch.qos.logback.classic.encoder.PatternLayoutEncoder
	import ch.qos.logback.core.ConsoleAppender
	import ch.qos.logback.core.filter.EvaluatorFilter
	import static ch.qos.logback.classic.Level.DEBUG
	import static ch.qos.logback.core.spi.FilterReply.DENY
	import static ch.qos.logback.core.spi.FilterReply.NEUTRAL
	appender("CONSOLE", ConsoleAppender) {
	encoder(PatternLayoutEncoder) {
	pattern = "[%thread] %-5level %logger{15} - %msg %n" }
	filter(EvaluatorFilter) {
	evaluator(GEventEvaluator) {
	expression = "!(e.getLoggerName().contains('com.finnjohnsen'))" }
	onMismatch = DENY onMatch = NEUTRAL }
	}
	appender("COLOR_CONSOLE", ConsoleAppender) {
	withJansi = true encoder(PatternLayoutEncoder) {
	pattern = "[%thread] %highlight(%-5level) %boldWhite(%logger{15}) - %boldYellow(%msg) %n" }
	}
	root(DEBUG, ["CONSOLE"])
	logger("com.finnjohnsen", DEBUG, ["COLOR_CONSOLE"])

2. Add this to your build.gradle (in addition to logback):

testCompile "org.fusesource.jansi:jansi:1.12"

Done.
