在函数外部的模块中使用pytest-variables

我正在使用PytestPytest-variablesparametrized test functions一起尝试减少测试用例中的代码重复。我在测试模块中使用硬编码字符串:类似于this;但是,我不知道如何从函数范围之外的变量文件中导入变量。非常感谢任何帮助,我理解使用pytest-variables可能无法做到这一点,但我想在这里发帖以确保我没有错过任何东西。

工作代码

import pytest

account_email_field = [
     ['test@google.com', 'Site Title', True],
     ['', '', False ],
     ['test@google.com', '', False ],
     ['', 'Default Title', False]
]

@pytest.fixture(params=account_email_field)
def email_field(request):
    return [request.param[0], request.param[1], request.param[2]]

def test_sample_spage(email_field):
    return [email_field[0], email_field[1], email_field[2]]

没有正常工作的代码,而是我想要的一个例子。

import pytest

account_email_field = [
     [variables['sample_email'], variables['site_title'], True],
     [variables['empty'], variables['empty'], False ],
     [variables['sample_email'], variables['empty'], False ],
     [variables['empty'], variables['site_title'], False]
]

@pytest.fixture(params=account_email_field)
def email_field(request):
    return [request.param[0], request.param[1], request.param[2]]

def test_sample_spage(email_field):
    return [email_field[0], email_field[1], email_field[2]]

我会使用静态类进行查找而不是字典,因为它更适合IDE。在文件constants.py(或其他名称)

class variables:
    sample_email = 'test@google.com'
    site_title = 'Site Title'
    empty = ''

然后在测试文件中

from constants import variables as var

account_email_field = [
     [var.sample_email, var.site_title, True  ],
     [var.empty,        var.empty,      False ],
     [var.sample_email, var.empty,      False ],
     [var.empty,        var.site_title, False ],
]

希望这有帮助!

pytest-variables插件将变量存储在config对象中,因此您可以从pytest_generate_tests钩子中访问它。

给出以下variables.json文件:

{
  "data": [
    ["test@google.com", "Site Title", true],
    ["", "Default Title", false]
  ]
}

使用以下test_param_vars.py文件:

def pytest_generate_tests(metafunc):
    if 'data' in metafunc.fixturenames:
        metafunc.parametrize('data', metafunc.config._variables['data'])

def test_variables(data):
    assert data[0]

您的输出应该类似于:

$ pytest test_param_variables.py --variables=variables.json -ra -s
