A function parse_config(config_text) is expected to raise a ValueError when the input is malformed. The test must verify that the exception is raised. Which assertion method should be used?

self.assertEqual(parse_config('bad config'), ValueError)

self.assertIn(ValueError, parse_config('bad config'))

self.assertRaises(ValueError, parse_config, 'bad config')

self.assertTrue(parse_config('bad config'))

A coverage report shows that a function has 100% line coverage, but a bug still exists in the function. What is the most likely reason for this?

The coverage tool is not measuring the correct module.

The tests do not cover all possible input values or branches, even though every line is executed.

The function contains a syntax error that is not detected by coverage.

The tests are not using the correct assertion methods.
