pytest-html报告中，添加描述

在conftest.py中实现

@pytest.mark.optionalhook
def pytest_html_results_summary(prefix, summary, postfix):
    prefix.extend([html.p("测试人: 电商测试组")])

@pytest.mark.optionalhook
def pytest_html_results_table_header(cells):
    cells.insert(1, html.th('Description'))
    cells.insert(2, html.th('Test'))  #增加一列，解决用例参数入参为中文时正常显示
    cells.pop(3) #将原有的test删除

@pytest.mark.optionalhook
def pytest_html_results_table_row(report, cells):
    cells.insert(1, html.td(report.description))
    cells.insert(2, html.td(report.nodeid))
    cells.pop(3)   

@pytest.mark.hookwrapper
def pytest_runtest_makereport(item, call):
    outcome = yield
    report = outcome.get_result()
    report.description = str(item.function.__doc__)
    report.nodeid = report.nodeid.encode("utf-8").decode("unicode_escape")  # 设置编码显示中文
