3 生成报告
3.1 插件执行方式
- 使用如下命令在命令行执行:
pytest --html=report.html
- 执行后,在当前目录下生成一个吗,名为
report.html
的报告: ![在这里插入图片描述](https://img-blog.csdnimg.cn/e6542cbeae7a4b86aa1599ceb348288e.png#pic_center =300x)
3.2 执行效果
3.3 指定报告生成的路径
- 当前目录下:
pytest --html=report.html
- 指定目录下:
pytest --html=./report/report.html
- 指定某个用例运行,生成报告保存到指定目录下:
pytest --html=./report/report.html
4 合并css
- 从生成的报告可以看出,除了
report.html
外,还有个文件style.css
; - 这个文件是报告的样式,是独立的,那么我们分享报告的时候,就必须把这个样式也加上,比较麻烦:
body

font-size: 12px;
/* do not increase min-width as some may use split screens */
min-width: 800px;

- 所以为了方便,我们把这个
css
样式合并到html
里,命令如下:
pytest --html=report.html --self-contained-html
- 再次运行报告查看下,此时只有
report.html
文件,且样式已经合并进来了:
5 报告中的行显示设置
- 默认生成功的报告中的所有行都是被展开的,如图:
- 我们可以自定义显示的样式:
?collapsed=Passed,XFailed,Skipped
6 报告增强
详细参考官网文档:https://github.com/pytest-dev/pytest-html
6.1 自定义css
- 可以使用
--CSS
选项在命令行上传递自定义CSS
:
$ pytest --html=report.html --css=highcontrast.css --css=accessible.css
6.2 报告标题
- 默认情况下,报告标题将是报告的文件名;
- 您可以使用
pytest_html_report_title
钩子对其进行编辑:
def pytest_html_report_title(report):
report.title = "My very own title!"
6.3 环境
Environment
部分由pytest-metadata
插件提供;- 可以通过
pytest_configure
和pytest_sessionfinish
钩子访问; - 要在运行测试之前修改
Environment
部分,请使用pytest_configure
:
def pytest_configure(config):
config._metadata["foo"] = "bar"
- 要在测试运行后修改
Environment
部分,请使用pytest_sessionfinish
:
import pytest
@pytest.hookimpl(tryfirst=True)
def pytest_sessionfinish(session, exitstatus):
session.config._metadata["foo"] = "bar"
[pytest]
environment_table_redact_list = ^foo$
.*redact.*
bar
6.4 其他摘要信息
- 可以使用
pytest_html_results_Summary
挂钩编辑Summary
部分:
from py.xml import html
def pytest_html_results_summary(prefix, summary, postfix):
prefix.extend([html.p("foo: bar")])
6.5 Extra内容
- 可以通过在报告对象上创建“
extra
”列表来向HTML
报告添加详细信息; - 以下是可以添加的
extra
内容类型:
- 注意:从文件添加图像时,路径可以是绝对路径,也可以是相对路径;
- 注意:当使用
--self-contained-html
时,作为文件或链接添加的图像可能无法按预期工作,有关详细信息,请参阅 Creating a self-contained report一节。 - 还有几种图像格式的方便类型:
- 以下示例使用
pytest_runtest_makereport
钩子添加了各种类型的附加功能,该钩子可以在plugin
或conftest.py
文件中实现:
import pytest
@pytest.hookimpl(hookwrapper=True)
def pytest_runtest_makereport(item, call):
pytest_html = item.config.pluginmanager.getplugin("html")
outcome = yield
report = outcome.get_result()
extra = getattr(report, "extra", [])
if report.when == "call":
# always add url to report
extra.append(pytest_html.extras.url("http://www.example.com/"))
xfail = hasattr(report, "wasxfail")
if (report.skipped and xfail) or (report.failed and not xfail):
# only add additional html on failure
extra.append(pytest_html.extras.html("<div>Additional HTML</div>"))
report.extra = extra
- 还可以为
html
以外的所有类型指定名称参数,这将更改创建的超链接的标题:
extra.append(pytest_html.extras.text("some string", name="Different title"))
- 还可以使用
fixture extra
直接在测试函数中添加内容,而不需要实现挂钩。这些通常会在插件添加任何额外功能之前结束。
from pytest_html import extras
def test_extra(extra):
extra.append(extras.text("some string"))
6.6 修改结果表
- 可以通过为表头和行实现自定义挂钩来修改报表的列;
- 以下示例
conftest.py
使用测试函数docstring
添加描述列,添加可排序时间列,并删除链接列:
from datetime import datetime
from py.xml import html
import pytest
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()
def pytest_html_results_table_row(report, cells):
cells.insert(2, html.td(report.description))
cells.insert(1, html.td(datetime.utcnow(), class_="col-time"))
cells.pop()
@pytest.hookimpl(hookwrapper=True)
def pytest_runtest_makereport(item, call):
outcome = yield
report = outcome.get_result()
report.description = str(item.function.__doc__)
- 还可以通过实现
pytest_html_results_table_row
钩子并删除所有单元格来删除结果。以下示例从报告中删除所有传递的结果:
def pytest_html_results_table_row(report, cells):
if report.passed:
del cells[:]
- 可以通过实现
pytest_HTML_results.HTML
钩子来修改日志输出和其他HTML
。以下示例用日志为空的通知替换所有其他HTML
和日志输出:
from py.xml import html
def pytest_html_results_table_html(report, data):
if report.passed:
del data[:]
data.append(html.div("No log output captured.", class_="empty log"))
var code = "43d4bcd6-e331-43c5-bf7b-1387d7988f7b"
