code-style UseAssertSameInsteadOfAssertTrue (PMD)

Use assertSame(x, y) instead of assertTrue(x==y), or assertNotSame(x,y) vs assertFalse(x==y)

This rule detects JUnit assertions in object references equality. These assertions should be made by more specific methods, like assertSame, assertNotSame.

public class FooTest extends TestCase {
 void testCode() {
  Object a, b;
  assertTrue(a==b); // bad usage
  assertSame(a, b);  // good usage
 }
}
