redundant-unittest-assert / W1503
=================================

**Message emitted:**

Redundant use of %s with constant value %r

**Description:**

*The first argument of assertTrue and assertFalse is a condition. If a constant is passed as parameter, that condition will be always true. In this case a warning should be emitted.*


**Correct code:**

.. code-block:: python

  import unittest
  
  
  class DummyTestCase(unittest.TestCase):
      def test_dummy(self):
          # Nothing, as an assert of a string literal will always pass


**Problematic code:**

.. code-block:: python

  import unittest
  
  
  class DummyTestCase(unittest.TestCase):
      def test_dummy(self):
          self.assertTrue("foo")  # [redundant-unittest-assert]
