## groovy.lang
Class GroovyLogTestCase

Helper class to spoof log entries as produced by calling arbitrary code. This allows non-intrusive testing of dependent objects without explicitly using Mock objects as long as those dependent objects do some proper logging. As a measure of last resort, it can be used on MetaClass to spoof it's log entries on 'invokeMethod'.
