pytest.param作为pytest.mark.parametrize的参数进行调用

pytest.param：在 pytest.mark.parametrize 中可以作为一个指定的参数进行调用
获取数据库（网页端）数据，通过pytest.param包装成数据包用于pytest.mark.parametrize 中实现数据驱动调用。

import os

from json import decoder
# from common.basic_module.Excel import ExcelReader
import requests
from run import Test_Plan_Url

TOPDIR = os.path.dirname(__file__)

# parse excel data: from flow or pytest
def generate_data(flow="", excel_path="Not Using", excel_name="Not Using"):
    print("\nflow id is: {}".format(flow))
    test_data = []
    if flow:
        response = requests.get(Test_Plan_Url + "=" + flow)
        if response.json()['success']:
            cases = response.json()['result']['cases']
            print(f"case num :{len(cases)}")
            for i in range (len(cases)):
                case = cases[i]
                id_flag = str(case["id"])                  
                case_title = case["caseName"]
                try:

        start_line = 2
        for i in range(start_line,reader.rows):

    print(test_data)
    print("debugging............\n")
    print(type(test_data))
    # execlcase顺序（导入顺序）和flow中id是对应的,但是flow传过来的case无序,需要按照case_id排序.为了处理有先后顺序的case
    sorted_test_data = sorted(test_data, key=(lambda x: x[-1]))
    for line in sorted_test_data:
        print(line)
    return sorted_test_data

测试函数中使用如下：

    @pytest.mark.parametrize("num_id, case_info", generate_data(FLOW_TEST_ID))
    def test_qemu(self, num_id, case_info):
        demo_info = case_info[1]
        pass
