python-如何使用py.test对多个项目执行多个测试

我是python和py.test的新手.我正在寻找一种在多个项目上运行多个测试但找不到的方法.我相信当您知道该怎么做时,它就非常简单.

我简化了我想做的事情,以使其易于理解.

如果我有一个Test类,它定义了一系列这样的测试：

class SeriesOfTests:
    def test_greater_than_30(self, itemNo):
        assert (itemNo > 30), "not greather than 30"
    def test_lesser_than_30(self, itemNo):
        assert (itemNo < 30), "not lesser thant 30"
    def test_modulo_2(self, itemNo):
        assert (itemNo % 2) == 0, "not divisible by 2"

我想对从类似函数获得的每个项目执行此SeriesOfTest：

def getItemNo():
    return [0,11,33]

我试图获得的结果是这样的：

RESULT : 
Test "itemNo = 0"
  - test_greater_than_30 = Failed
  - test_lesser_than_30 = success
  - test_modulo_2 = success

Test "itemNo = 11"
  - test_greater_than_30 = Failed
  - test_lesser_than_30 = success
  - test_modulo_2 = Failed

Test "itemNo = 33"
  - test_greater_than_30 = success
  - test_lesser_than_30 = Failed
  - test_modulo_2 = Failed

我该如何使用py.test？

解决方法:

忘记先前的答案.假设您需要按值对测试进行分组,则可以使用scenarios.我刚刚从文档中修改了示例：

import pytest

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, scope="class")

scenario1 = ('itemNo = 0', {'itemNo': 0})
scenario2 = ('itemNo = 11', {'itemNo': 11})
scenario3 = ('itemNo = 33', {'itemNo': 33})

class TestSeries:
    scenarios = [scenario1, scenario2, scenario3]

    def test_greater_than_30(self, itemNo):
        assert (itemNo > 30), "not greather than 30"
    def test_lesser_than_30(self, itemNo):
        assert (itemNo < 30), "not lesser thant 30"
    def test_modulo_2(self, itemNo):
        assert (itemNo % 2) == 0, "not divisible by 2"

输出为：

$py.test -v

我认为那是最接近的.
