Class LogRule

java.lang.Object

org.xwiki.test.LogRule

All Implemented Interfaces:

org.junit.rules.TestRule

Deprecated.

starting with 7.0M1 you should use AllLogRule instead since we want tests to not output anything to the console

@Deprecated
public class LogRule
extends Object
implements org.junit.rules.TestRule

Allow capturing Logs output in the Class under test during unit testing. This is useful for two reasons:

• it allows not outputting log messages in the console which is a bad practice. When a test run it should not output anything and if it needs to assert something, it has to be done in the test itself.
• it allows to assert the output log messages

This code was inspired by code written by Christian Baranowski in a blog post.

Example usage:

  @Rule public LogRule logRule = new LogRule() {{
      record(LogLevel.WARN);
      recordLoggingForType(RestrictParseLocationEventHandler.class);
  }};

4.2RC1
