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-family: Helvetica, Arial, sans-serif;
font-size: 12px;
/* do not increase min-width as some may use split screens */
min-width: 800px;
color: #999;
}
h1 {
font-size: 24px;
color: black;
}
h2 {
font-size: 16px;
color: black;
}
p {
color: black;
}
a {
color: #999;
}
table {
border-collapse: collapse;
}
/******************************

#environment td {

/*------------------

#results-table {

font-size: 12px;

/*------------------

.sort-icon {

border-top: 8px solid #999;
}
- 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"
请注意,在上面的示例中,@pytest.hookimpl(tryfirst=True)非常重要,因为这可以确保在任何其他插件(包括pytest-html和pytest-metadata)运行之前尽最大努力运行pytest_sessionfinish。如果省略了这一行,那么Environment表将不会更新,因为插件的pytest_sessionfinish将首先执行,因此不会接受您的更改。
除非元数据是集合.OrderedDict,否则生成的表将按字母顺序排序。
可以从环境表中编辑变量。重做的变量将显示其名称,但其值将灰显。这可以通过在INI配置文件(例如:pytest.INI)中设置environment_table_redact_list来实现。environment_table_redact_list是正则表达式的行列表。与此列表中的正则表达式匹配的任何环境表变量都会对其值进行编校。
例如,以下命令将对与正则表达式^foo$、.*redact.*或bar匹配的所有环境表变量进行编校:
[pytest]
environment_table_redact_list = ^foo$
.*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:
Type |
Example |
---|---|
Raw HTML |
|
|
|
Plain text |
|
URL |
|
Image |
|
Image |
|
Image |
|
- 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:
Image format |
Example |
---|---|
PNG |
|
JPEG |
|
SVG |
|
- 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"))
