如何将一个字符串拆分成多行，其中字符串完全相同

Question

这是一个简单的单元测试：

@pytest.mark.parametrize(
    "card, expected",
    [
        (
            Sneeze(),
            "+---------------------+   \n|        Sneeze       |   \n|---------------------|   \n| Suit:      Accident |   \n| Rank:          Jack |   \n| Energy_cost:      1 |   \n| Damage:           1 |   \n|                     |   \n|---------------------|   \n|        Achoo!       |   \n+---------------------+   \n",
        ),
        (
            ThrowCard(),
            "+---------------------+   \n|      Card Throw     |   \n|---------------------|   \n| Suit:        Attack |   \n| Rank:          Jack |   \n| Energy_cost:      2 |   \n| Damage:           2 |   \n|                     |   \n|---------------------|   \n|      Ricky Jay?     |   \n+---------------------+   \n",
        ),
    ],
)
def test_display_cards(capsys, card, expected):
    testdeck = [card]
    display_cards(testdeck)
    captured = capsys.readouterr()
    assert captured.out == expected

300 个字符串有点笨重，flake8 也同意。但是，如果我使用通常的方法将其拆分：

@pytest.mark.parametrize(
    "card, expected",
    [
        (
            Sneeze(),
            '''
            +---------------------+
            |        Sneeze       |
            |---------------------|
            | Suit:      Accident |
            | Rank:          Jack |
            | Energy_cost:      1 |
            | Damage:           1 |
            |                     |
            |---------------------|
            |        Achoo!       |
            +---------------------+''',

@pytest.mark.parametrize(
    "card, expected",
    [
        (
            Sneeze(),
            "+---------------------+   \n|        \
                Sneeze       |   \n|---------------------|  \
                      \n| Suit:      Accident |   \n| Rank:  \
                                      Jack |   \n| Energy_cost:      1 |   \n| Damage:       \
                                                1 |   \n|                     |   \n|---------------------|   \n|  \
                                                                Achoo!       |   \n+---------------------+   \n",
        ),

这两个在技术上都不属于“完全相同”的相同字符串，并且测试失败。我该怎么办？ 这个方法也行不通

如何将长字符串的定义拆分为多行？

@pytest.mark.parametrize(
    "card, expected",
    [
        (
            Sneeze(),
            ("+---------------------+   "
            "|        Sneeze       |   "
            "|---------------------|   "
            "| Suit:      Accident |   "
            "| Rank:          Jack |   "
            "| Energy_cost:      1 |   "
            "| Damage:           1 |   "
            "|                     |   "
            "|---------------------|   "
            "|        Achoo!       |   "
            "+---------------------+   \n"),
        ),

最终代码：

@pytest.mark.parametrize(
    "card, expected",
    [
        (
            Sneeze(),
            ("+---------------------+   \n"
            "|        Sneeze       |   \n"
            "|---------------------|   \n"
            "| Suit:      Accident |   \n"
            "| Rank:          Jack |   \n"
            "| Energy_cost:      1 |   \n"
            "| Damage:           1 |   \n"
            "|                     |   \n"
            "|---------------------|   \n"
            "|        Achoo!       |   \n"
            "+---------------------+   \n"),
        ),
