Python3.x 在多个测试中维护和报告变量

我们如何在多个测试中维护一个变量并将其报告(在控制台或文件中)？

假设您在一个名为math_operations.py的模块中有一个计算两个数字之和的函数:

# math_operations.py

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

让我们创建一个名为test_math_operations.py的带有两个测试的Pytest模块.我想要保持两个测试的总分:

# test_math_operations.py
import pytest
from math_operations import add_numbers

@pytest.fixture
def score():
    return {"score_pos": 0, "score_neg": 0}

def test_add_numbers_positive(score):
    result = add_numbers(2, 3)
    assert result == 5
    score["score_pos"] =2
    assert score["score_pos"] == 2


def test_add_numbers_negative(score):
    result = add_numbers(-5, 10)
    assert result == 5
    score["score_neg"] = 3
    assert score["score_neg"] == 3

#print(score)

@R.K收到 comments 后Updated test_math_operations.py(见下文)

# test_math_operations.py
import pytest
from math_operations import add_numbers

class DemoClass:
  score_pos = 0
  score_neg = 0

@pytest.fixture() # (score="class")
def score():
  test = DemoClass
  yield test

scoreClass = DemoClass()

class TestDemo:
    global scoreClass
    def test_add_numbers_positive(score):
        result = add_numbers(2, 3)
        assert result == 5
        scoreClass.score_pos =2

    def test_add_numbers_negative(score):
        result = add_numbers(-5, 10)
        assert result == 5
        scoreClass.score_neg = 3

print(scoreClass.score_neg, scoreClass.score_neg)

如果我不能得到乐谱词典给我，我想要分数的总价值.

任何帮助都将不胜感激.
