SLF4J Test provides JUnit Platform extension which can registered via annotation:
import org.junit.jupiter.api.extension.ExtendWith;
import com.github.valfirst.slf4jtest.TestLoggerFactoryExtension;
@ExtendWith(TestLoggerFactoryExtension.class)
class BasicJUnit5Test {
...
}
SLF4J Test supports automatic extension registration via ServiceLoader mechanism. This feature is considered advanced in JUnit Platform and it requires explicit enabling.
See https://valfirst.github.io/slf4j-test/ for details.
This project is based on the original implementation by Robert Elliot, located at https://github.com/Mahoney/slf4j-test which worked with SLF4J prior to version 1.8.X.
