/**
 * Container for all test logging related options. Different options
 * can be set for each log level. Options that are set directly (without
 * specifying a log level) apply to log level LIFECYCLE. Example:
 *
 * <pre class='autoTested'>
 * apply plugin: 'java'
 *
 * test {
 *     testLogging {
 *         // set options for log level LIFECYCLE
 *         events "failed"
 *         exceptionFormat "short"
 *
 *         // set options for log level DEBUG
 *         debug {
 *             events "started", "skipped", "failed"
 *             exceptionFormat "full"
 *         }
 *
 *         // remove standard output/error logging from --info builds
 *         // by assigning only 'failed' and 'skipped' events
 *         info.events = ["failed", "skipped"]
 *     }
 * }
 * </pre>
 *
 * The defaults that are in place show progressively more information
 * on log levels WARN, LIFECYCLE, INFO, and DEBUG, respectively.
