Pytest plugin for generating HTML reports with per-test profiling and optionally call graph visualizations. Based on pytest-html by Dave Hunt.

Project description

pytest-html-profiling is a plugin for pytest based on the pytest-html plugin that generates a HTML report for the test results along with profiling results and call graphs.

License PyPI Conda Forge Travis Issues Requirements


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

  • Python 2.7, pytest-metadata, pygraphviz, gprof2dot


To install pytest-html-profiling:

$ pip install pytest-html-profiling

Then run your tests with:

$ pytest --html=report.html --html-profiling --html-call-graph

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.

Enhancing reports


Custom CSS (Cascasding Style Sheets) can be passed on the command line using the --css option. These will be applied in the order specified, and can be used to change the appearance of the report.

$ pytest --html=report.html --css=highcontrast.css --css=accessible.css


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'

The generated table will be sorted alphabetically unless the metadata is a collections.OrderedDict.

Additional summary information

You can edit the Summary section by using the pytest_html_results_summary hook:

import pytest
from py.xml import html

def pytest_html_results_summary(prefix, summary, postfix):
    prefix.extend([html.p("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:




extra.html('<div>Additional HTML</div>')


extra.json({'name': 'pytest'})

Plain text

extra.text('Add some simple Text')




extra.image(image, mime_type='image/gif', extension='gif')





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

There are also convenient types for several image formats:

Image format








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

import pytest
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
        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 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

def pytest_html_results_table_header(cells):
    cells.insert(1,'Time', class_='sortable time', col='time'))

def pytest_html_results_table_row(report, cells):
    cells.insert(1,, class_='col-time'))

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

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

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

Display options

By default, all rows in the Results table will be expanded except those that have Passed.

This behavior can be customized with a query parameter: ?collapsed=Passed,XFailed,Skipped.
