Question

我正在运行python coverage，但是覆盖率不是100％。

def add(a, b):
    return a + b

test_utils.py

from python_coverage import utils
import unittest


class TestAdd(unittest.TestCase):
    """
    Test the add function from the mymath library
    """

    def test_add_integers(self):
        """
        Test that the addition of two integers returns the correct total
        """
        result = utils.add(1, 2)
        self.assertEqual(result, 3)

    def test_add_floats(self):
        """
        Test that the addition of two floats returns the correct result
        """
        result = utils.add(10.5, 2)
        self.assertEqual(result, 12.5)

    def test_add_strings(self):
        """
        Test the addition of two strings returns the two string as one
        concatenated string
        """
        result = utils.add('abc', 'def')
        self.assertEqual(result, 'abcdef')

if __name__ == '__main__':
    unittest.main()

覆盖率报告-m

Answer 1

您没有测试方法的输出。这项测试：

r = utils.add(2,3)
self.assertEqual(5,5)

实际上并没有测试r的值。尝试将其更改为：

r = utils.add(2, 3)
self.assertEqual(r, 5)

与TestAdd.test_add_float相同。

python coverage缺少测试
