@GwtCompatible @NullMarked public class TestLogHandler extends Handler
Tests may use this to intercept messages that are logged by the code under test. Example: 
  TestLogHandler handler;

  protected void setUp() throws Exception {
    super.setUp();
    handler = new TestLogHandler();
    SomeClass.logger.addHandler(handler);
    addTearDown(new TearDown() {
      public void tearDown() throws Exception {
        SomeClass.logger.removeHandler(handler);
      }
    });
  }

  public void test() {
    SomeClass.foo();
    LogRecord firstRecord = handler.getStoredLogRecords().get(0);
    assertEquals("some message", firstRecord.getMessage());
  }
