问题描述
我正在使用
- Python 3.6
- Pytest 6.1.1
- Pytest xdist 2.1.0
- Pycharm 2018.3.7
我正在通过pycharm> pytest运行自动化测试，参数如下：
--html=../../reports/report.html --self-contained-html -n 1 -k test_instalment_mtn_ng_unified_eco
为了在硒期间捕获屏幕，我正在使用多重处理， 开始捕获，然后继续测试
如果我不在参数-n 1中使用（表示没有工作人员）-test成功通过了测试（包括屏幕捕获）
如果我使用-n 1（表示1个工作人员）pytest，则出现以下错误：

用Google搜索了2天，却没有找到可能的原因 附加部分测试代码 预先感谢

解决方法
几天前，我遇到了相同的错误，发现该错误位于record_property固定装置中
由于某些原因，record_property固定装置不接受接收某些类型的数据。就我而言，我试图将response从API请求传递到record_property固定装置，例如：
record_property("api_res",res)
经过几次尝试，我创建了一种解决方法，可以通过record_property固定装置从API请求发送响应，并存储所需的信息：
@pytest.fixture
def store_api_response(record_property,request):
record_property(
'api_res',{
'request_url': str(response.request.method + env + response.request.path_url),'headers': dict(response.request.headers),'request_body': response.request.body,'response_body': response_body,'status_code': str(response.status_code)
}
)
return get_response
对于您而言，该错误恰好发生在此行上：
record_property("test_returns",{"screen_recorder": video_record})
record_property固定装置不接受存储在video_record变量中的数据
