pytest plugin for generating HTML reports

Project Description

pytest-html is a plugin for pytest that generates a HTML report for the test results.

Requirements

You will need the following prerequisites in order to use pytest-html:

  • Python 2.7, 3.6, PyPy, or PyPy3

Installation

To install pytest-html:

$ pip install pytest-html

Then run your tests with:

$ pytest --html=report.html

ANSI codes

Note that ANSI code support depends on the ansi2html package. Due to the use of a less permissive license, this package is not included as a dependency. If you have this package installed, then ANSI codes will be converted to HTML in your report.

Creating a self-contained report

In order to respect the Content Security Policy (CSP), several assets such as CSS and images are stored separately by default. You can alternatively create a self-contained report, which can be more convenient when sharing your results. This can be done in the following way:

$ pytest --html=report.html --self-contained-html

Images added as files or links are going to be linked as external resources, meaning that the standalone report HTML-file may not display these images as expected.

The plugin will issue a warning when adding files or links to the standalone report.

Enhancing reports

Environment

The Environment section is provided by the pytest-metadata, plugin, and can be accessed via the pytest_configure hook:

def pytest_configure(config):
    config._metadata['foo'] = 'bar'

Extra content

You can add details to the HTML reports by creating an ‘extra’ list on the report object. Here are the types of extra content that can be added:

Type Example
Raw HTML extra.html('<div>Additional HTML</div>')
JSON extra.json({'name': 'pytest'})
Plain text extra.text('Add some simple Text')
URL extra.url('http://www.example.com/')
Image extra.image(image, mime_type='image/gif', extension='gif')
Image extra.image('/path/to/file.png')
Image extra.image('http://some_image.png')

Note: When adding an image from file, the path can be either absolute or relative.

Note: When using --self-contained-html, images added as files or links may not work as expected, see section Creating a self-contained report for more info.

There are also convenient types for several image formats:

Image format Example
PNG extra.png(image)
JPEG extra.jpg(image)
SVG extra.svg(image)

The following example adds the various types of extras using a pytest_runtest_makereport hook, which can be implemented in a plugin or conftest.py file:

import pytest
@pytest.mark.hookwrapper
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

You can also specify the name argument for all types other than html which will change the title of the created hyper link:

extra.append(pytest_html.extras.text('some string', name='Different title'))

Modifying the results table

You can modify the columns by implementing custom hooks for the header and rows. The following example conftest.py adds a description column with the test function docstring, adds a sortable time column, and removes the links column:

from datetime import datetime
from py.xml import html
import pytest

@pytest.mark.optionalhook
def pytest_html_results_table_header(cells):
    cells.insert(2, html.th('Description'))
    cells.insert(0, 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(datetime.utcnow(), class_='col-time'))
    cells.pop()

@pytest.mark.hookwrapper
def pytest_runtest_makereport(item, call):
    outcome = yield
    report = outcome.get_result()
    report.description = str(item.function.__doc__)

You can also remove results by implementing the pytest_html_results_table_row hook and removing all cells. The following example removes all passed results from the report:

import pytest

@pytest.mark.optionalhook
def pytest_html_results_table_row(report, cells):
    if report.passed:
      del cells[:]

The log output and additional HTML can be modified by implementing the pytest_html_results_html hook. The following example replaces all additional HTML and log output with a notice that the log is empty:

import pytest

@pytest.mark.optionalhook
def pytest_html_results_table_html(report, data):
    if report.passed:
        del data[:]
        data.append(html.div('No log output captured.', class_='empty log'))
