How to get access to appender methods with SLF4J?

[emelyanovkr]

I am getting my Logger like this private final Logger LOGGER = LoggerFactory.getLogger("TestLogger"). I am using ListAppender behind TestLogger name, so I want to get access to ListAppender fields and get the List of LogEvents to write unit tests ensuring messages are capturing as needed,

I am using log4j-core-test 2.23.1 and slf4j 2.0.12.

You just need to use ListAppender.getListAppender() with the name of your appender:

logging-log4j2/log4j-core-test/src/main/java/org/apache/logging/log4j/core/test/appender/ListAppender.java

Lines 292 to 302 in fe92961

	/**
	* Gets the named ListAppender if it has been registered.
	*
	* @param name the name of the ListAppender
	* @return the named ListAppender or {@code null} if it does not exist
	* @see org.apache.logging.log4j.core.test.junit.LoggerContextRule#getListAppender(String)
	*/
	public static ListAppender getListAppender(final String name) {
	return ((ListAppender)
	(LoggerContext.getContext(false)).getConfiguration().getAppender(name));
	}

So that's simple, I was going throguh the code but seems like I wasn't checking carefully, so I missed out this method. Thank you!
