是否有类似Spock的Python测试库

Question

我和Spock合作并喜欢'where'子句,它允许您轻松地使用多个输入和输出来运行测试用例.例如:

class HelloSpock extends spock.lang.Specification {
    def "length of Spock's and his friends' names"() {
        expect:
            name.size() == length

        where:
            name     | length
            "Spock"  | 5
            "Kirk"   | 4
            "Scotty" | 6
    }
} 

Python有类似的东西吗？

Answer 1

就在这里！

我是Nimoy的作者——一个旨在成为 Python 的 Spock 的框架。

您可以创建数据驱动的测试：

from nimoy.specification import Specification

class MySpec(Specification):

    def my_feature_method(self):
        with given:
            a = value_of_a
            b = value_of_b

        with expect:
            (a * b) == expected_value

        with where:
            value_of_a | value_of_b | expected_value
            1          | 10         | 10
            2          | 20         | 40

您可以进行模拟：

from unittest import mock
from nimoy.specification import Specification

class MySpec(Specification):

    def my_feature_method(self):
        with setup:
            the_mock = mock.Mock()

        with when:
            the_mock.some_method() << [5, 6, 7]

        with then:
            the_mock.some_method() == 5
            the_mock.some_method() == 6
            the_mock.some_method() == 7

我们也有非常模拟的断言：

from unittest import mock
from nimoy.specification import Specification

class MySpec(Specification):

    def my_feature_method(self):
        with setup:
            the_mock = mock.Mock()

        with when:
            the_mock.some_method('abcd', True)

        with then:
            1 * the_mock.some_method('abcd', True)

Answer 2

pytest可以参数化测试功能：

import pytest
@pytest.mark.parametrize(("input", "expected"), [
    ("3+5", 8),
    ("2+4", 6),
    ("6*9", 42),
])
def test_eval(input, expected):
    assert eval(input) == expected

Answer 3

我也非常喜欢 Java/Groowy 世界中的 Spock 框架。在 Python 中搜索类似。在我的搜索中，我发现nimoy看起来非常有前途。

来自官方页面的示例：

from nimoy.specification import Specification

class MySpec(Specification):

    def my_feature_method(self):
        with given:
            a = value_of_a
            b = value_of_b

        with expect:
            (a * b) == expected_value

        with where:
            value_of_a | value_of_b | expected_value
            1          | 10         | 10
            2          | 20         | 40
