AttributeError: ‘TestReport’ object has no attribute ‘description’

在conftest文件增加报告描述，如下：

@pytest.mark.optionalhook
def pytest_html_results_table_header(cells):
    cells.insert(2, html.th('Description'))
    cells.insert(1, html.th('Time', class_='sortable time', col='time'))
    cells.pop()

@pytest.mark.optionalhook
def pytest_html_results_table_row(report, cells):
    cells.insert(2, html.td(report.description))
    cells.insert(1, html.td(time.strftime("%Y-%m-%d %H:%M:%S", time.localtime()), class_='col-time'))
    cells.pop()

但是运行后会报错误，AttributeError: ‘TestReport’ object has no attribute ‘description’：

AttributeError: 'TestReport' object has no attribute 'description'

此时我们只需要在conftest文件下加如下钩子函数就可以完美解决：

@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
