在pytest的conftest.py中设置测试执行顺序，参数化测试

Question

conftest.py:

def pytest_collection_modifyitems(config, items):
    def param_part(item):
        # check for the wanted module and test class
        if item.nodeid.startswith("test_urls.py::TestSSL::"):
            # find the start of the parameter part in the nodeid
            index = item.nodeid.find('[')
            if index > 0:
                # sort by parameter name
                return item.name[item.nodeid.index('['):]

        # for all other cases, sort by node id as usual
        return item.nodeid

    # re-order the items using the param_part function as key
    items[:] = sorted(items, key=param_part)

# def test_close_browser():

        logging.error('Error - close_browser module', exc_info=True)
        assert False

结果： 现在测试执行序列 - https://prnt.sc/ttw4or conftest 还按名称（字母）对测试进行排序，我需要删除此依赖项。

目标结果： 测试执行顺序需要 - test_go_ca_sslcheck() > 使用第一个 url 进行类迭代 > 使用下一个 url 进行类迭代，直到它们结束 > def test_close_browser()

注意： 也许有更简单的方法可以实现目标，请详细描述，我的知识非常有限。提前谢谢！

如果我现在理解正确，您不想更改默认排序顺序，参数化测试除外。
这是一个稍微复杂的改编版本，可以做到这一点（我试图添加足够多的 cmets 来解释它）：

def pytest_collection_modifyitems(config, items):
    def param_part(item):
        index = item.name.find('[')
        if index > 0:
            # revert the name and parameter parts, so tests are sorted by
            # parameter first and name second
            return (item.name[item.name.index('['):]
                    + item.name[:item.name.index('[')])
        return item.name

    class_id = "test_urls.py::TestSSL::"
    # find the first test in the class to be sorted
    start_index = next((i for (i, item) in enumerate(items)
                        if item.nodeid.startswith(class_id)), -1)
    if start_index != -1:
        # ... and the first test after the class
        # (have to start the first at start_index)
        end_index = next((i + start_index for (i, item)
                          in enumerate(items[start_index:])
                          if not item.nodeid.startswith(class_id)), -1)
        # sort only the items in the class and let the rest alone
        items[start_index:end_index] = sorted(items[start_index:end_index],
                                              key=param_part)
    # for any other tests without our class we leave the items alone

这给出了pytest -vv test_urls.py 的输出：
