Description:

Avoid negation in an assertTrue or assertFalse test. For example, rephrase: assertTrue(!expr); as: assertFalse(expr);

public class SimpleTest extends TestCase {
 public void testX() {
  assertTrue("not empty", !r.isEmpty()); // replace with assertFalse("not empty", r.isEmpty())
  assertFalse(!r.isEmpty()); // replace with assertTrue(r.isEmpty())
 }
}
