EugeneLoy / Log test names (JUnit, SLF4J)
Last active August 29, 2015 14:02
Add this field to your test class to log names of the tests when they start. Works with JUnit 4.9+ and SLF4J.
@Rule
public TestRule loggingRule = new TestWatcher() {
protected void starting(Description description) {
Logger logger = LoggerFactory.getLogger(description.getClassName());
logger.info("Starting: {}", description.getMethodName());
}
};
