Following up on the logging blog post.

When creating and later running tests it could be equally helpful with some good logs.

Configuring test logging is done with either logback-test.groovy or logback-test.xml which should be placed in the resources directory within the test directory.

logback-test.groovy

import org.springframework.boot.logging.logback.ColorConverter
import org.springframework.boot.logging.logback.WhitespaceThrowableProxyConverter
import java.nio.charset.StandardCharsets

conversionRule 'clr', ColorConverter
conversionRule 'wex', WhitespaceThrowableProxyConverter

// See http://logback.qos.ch/manual/groovy.html for details on configuration
appender('STDOUT', ConsoleAppender) {
    encoder(PatternLayoutEncoder) {
        charset = StandardCharsets.UTF_8

        pattern =
                '%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} ' + // Date
                        '%clr(%5p) ' + // Log level
                        '%clr(---){faint} %clr([%15.15t]){faint} ' + // Thread
                        '%-50.50(%logger{35}.%M) %4.4line .' + // Logger with method name
                        '%m%n%wex' // Message
    }
}

root(ERROR, ['STDOUT'])
logger("no.prpr", DEBUG, ['STDOUT'], false)

And then setting up the integration test something like:

@Integration
@Rollback
@Slf4j
class SecurityMaintenanceServiceIntegrationSpec extends Specification {

    final static String TENANT = 'test'
 
 
    def setupSpec() {
        log.debug('setupSpec')
        System.setProperty(SystemPropertyTenantResolver.PROPERTY_NAME, TENANT)
    }
}

@Slf4j makes logging available for the test.
