Question

我需要一个初始化变量的夹具（会话？），该变量将在测试中用于生成测试输出。我不需要在每个测试中都运行此固定装置，而仅在测试初始化期间运行。该变量需要在测试中用于参数化。

在conftest.py中：

import os
import json
import glob
import csv
from gbl import *

def pytest_addoption(parser):
    parser.addoption("--component", action="append", default=[], help="component to test")

def pytest_generate_tests(metafunc):
    metafunc.parametrize("code", DTCLIST)

@pytest.fixture(scope="session", autouse=True)
def my_own_session_run_at_beginning(request):
    print('\nIn my_own_session_run_at_beginning()')
    GlobalDatabase = dict()
    GlobalDataBaseName = os.path.join('c', 'myfolder', '10_Requirement', 'db.json')
    with open(GlobalDataBaseName, 'r') as fp:
        GlobalDatabase = json.load(fp)['codes']

    component = request.config.getoption('component')[0]
    diagCfg = list()
    sources = ''
    if component != 'all':
        DTCFiles = glob.glob(os.path.join('c', 'myfolder', '*',
                                          component, '20_SystemDesign', , '*.dtc'))
        SrcFiles = glob.glob(os.path.join('c', 'myfolder', '*',
                                          component, '40_SystemDesign', '*.c'))
    else:
        DTCFiles = glob.glob(os.path.join('c', 'myfolder', '*',
                                          '*', '20_SystemDesign',  '*.dtc'))
        SrcFiles = glob.glob(os.path.join('c', 'myfolder', '*',
                                          '*', '40_SystemDesign', '*.c'))
    for DTCFile in DTCFiles:
        with open(DTCFile, 'r') as csvFile:
            csvLine = csv.reader(csvFile, delimiter=';')
            for row in csvLine:
                if row:
                    diagCfg.append({'code': row[0], 'SWName': row[1], 'fileName': DTCFile})

    for SrcFile in SrcFiles:
        with open(SrcFile, 'r') as fp:
            for line in fp:
                sources += line

    GLOBALDB = GlobalDatabase
    DTCLIST = diagCfg
    SOURCESBUFFER = sources

gbl.py：

DTCLIST = list()
GLOBALDB = dict()
SOURCESBUFFER = ''

testdtc.py：

import re
import pytest
from gbl import *

def test_dtc_code_syntax(code):
    assert re.match('\d+\.\d+\.\d+', code['code']), "{} does not have a proper syntax.".format(code['code'])

我希望函数my_own_session_run_at_beginning可以运行，但是在运行命令时：

pytest -v -s --component all testdtc.py

我陷入了跳过测试的情况

有人对此有解决方案吗？

非常感谢您
