Bug description:
  1)signature for  assertTure:
      def failUnless(self, expr, msg=None):
          """Fail the test unless the expression is true."""
          if not expr: raise self.failureException, msg
       ....................................
  assert_ = assertTrue = failUnless

  2) signature for assertEqual:    
      def failUnlessEqual(self, first, second, msg=None):
          """Fail if the two objects are unequal as determined by the '=='
             operator.
          """
          if not first == second:
              raise self.failureException, \
                    (msg or '%r != %r' % (first, second))
            ...........................
        assertEqual = assertEquals = failUnlessEqual

  assertTrue used to evaluate  one expression
  assertEqual used to compare two  expressions

  If passed two expressions to assertTrue  , it always evaluate first
  expression . That 's not expected .
