pytest无法收集测试用例：执行返回no tests found/Empty suite

问题现象 #

通过PyCharm运行测试或终端执行python -m pytest、pytest命令时，均返回无测试用例被收集：

PyCharm运行输出：

/Users/usr/PycharmProjects/project/bin/python /Applications/PyCharm CE.app/Contents/plugins/python-ce/helpers/pycharm/_jb_pytest_runner.py --path /Users/usr/PycharmProjects/project/tests/test_google_maps_api.py

终端执行输出：

已尝试的解决方案 #

• 在各目录添加/移除__init__.py文件
• 在各目录添加/移除conftest.py文件
• 修改workfiles文件夹名称为test/tests
• 将所有方法/函数命名为test_...格式
• 设置pytest为默认测试运行器
• 将autom_api_project目录设为项目结构中的Content Root
• 清理缓存并重启PyCharm
• 在根目录添加空的tests.py文件
• 其他已遗忘的尝试

现寻求该问题的有效解决方案。
