pytest 在课堂中以正确的顺序运行场景

本文介绍了pytest 在课堂中以正确的顺序运行场景的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

所以我有以下结构:

class Test(object):

   def test_1(self):
      pass

   def test_2(self):
      pass

   def test_3(self):
      pass

它运行良好，现在我正在添加场景"(正如 pytest - testscenarios"的快速移植):

it runs great, NOW I'm adding the "scenarios" (as it's recommended at pytest - A quick port of "testscenarios"):

def pytest_generate_tests(metafunc):
    idlist = []
    argvalues = []
    for scenario in metafunc.cls.scenarios:
        idlist.append(scenario[0])
        items = scenario[1].items()
        argnames = [x[0] for x in items]
        argvalues.append(([x[1] for x in items]))
    metafunc.parametrize(argnames, argvalues, ids=idlist)

class Test(object):
       scenarios = ['1' {'arg':'value1'},
                    '2' {'arg':'value2'}]

       def test_1(self, arg):
          pass

       def test_2(self, arg):
          pass

       def test_3(self, arg):
          pass

当我运行它时测试顺序错误，我得到:

When I run it the ORDER of tests is wrong, I get:

test_1[1]  
test_1[2]  
test_2[1]   
test_2[2]  
test_3[1]  
test_3[2]

看起来不像是 Test 类的场景.

Doesn't really look like a scenario for the Test class.

问题:是否有以正确顺序运行它的解决方案?喜欢:

QUESTION: Is the any solution to run it in the correct order? like:

test_1[1]
test_2[1]
test_3[1]
test_1[2]
test_2[2]
test_3[2]

推荐答案

即将推出的 pytest-2.3 支持更好的(基于资源的)排序，我刚刚更新了文档中的场景示例:https://docs.pytest.org/en/latest/示例/parametrize.html#a-quick-port-of-testscenarios

The upcoming pytest-2.3 has support for better (resource-based) ordering, and i just updated the scenario example in the docs: https://docs.pytest.org/en/latest/example/parametrize.html#a-quick-port-of-testscenarios

您可以使用

pip install -i http://pypi.testrun.org -U pytest

并且应该使用py.test --version"获取 pytest-2.3.0.dev15 并能够使用它.

and should get pytest-2.3.0.dev15 with "py.test --version" and be able to use it.
