Different logging services can be tested using mock loggers backed by Mockito.
Warning
This library does not support parallel test execution.
The simplest usage example looks like this:
@Test
void helloWorld() {
var helloService = new HelloService();
assertDoesNotThrow(helloService::sayHelloWorld);
verify(System.getLogger("HelloService")).log(Level.INFO, "Hello World!");
}Now this library implements services for JDK Platform Logging, Apache Commons Logging and SLF4J.
See more examples in the relevant modules of this project:
- for Apache Commons Logging in mock-loggers-commons-logging
- for JDK Platform Logging in mock-loggers-jdk-platform-logging
- for SLF4J in mock-loggers-slf4j
- Apache Log4j: Unit Testing in Maven
- Unit Test logback Using JUnit, it's old but gold
There are two projects which inspired me to make this library:
