Class TestRunnerPerformanceLogger

java.lang.Object

de.gebit.integrity.runner.logging.TestRunnerPerformanceLogger

public class TestRunnerPerformanceLogger
extends Object

This performance logging service is used to execute several performance-critical segments of test execution. It allows to print out start/end markers for the performance-relevant sections as well as their (total) duration.

By default, this data is NOT logged. You can enable logging by specifying the system property PERFORMANCE_LOG_ENABLE_PROPERTY with value "true".
