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:

import unittest


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

Problematic code:

import unittest


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