Choose pytest-html if you want documented controls for customizing, filtering and sorting a report, plus an option to make its CSS and assets self-contained. Consider pytest-html-reporter if its built-in overview, trends, history, failure screenshots and rerun support fit your reporting workflow. Neither is a universal winner: published requirements and release dates do not prove compatibility with your exact Python, pytest and xdist versions, so validate your chosen versions in CI before adopting them.
What each plugin offers
pytest-html-reporter: built-in report features
The PyPI project page describes pytest-html-reporter as a static HTML report generator. Its listed features include an overview, trends, suite highlights, test-suite details, archives and history, screenshots on failure, and rerun support. Those built-ins may suit a team that wants these views without assembling them from supplemental report data.
The documented installation command is pip3 install pytest-html-reporter. Its default output is report/pytest_html_reporter.html. Use --html-report to set a report path or filename and --title to set its title; the package page also says these options can be placed in pytest.ini.
pytest-html: customization and sharing controls
pytest-html is the official pytest plugin for generating an HTML test-results report; its documentation describes it as “a plugin for pytest that generates a HTML report for test results.” The installation guide gives pip install pytest-html and states Python >=3.6 or PyPy3.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
The user guide documents controls for custom CSS, report-title and summary hooks, environment details, custom result-table content, and text, JSON, URL and image extras. You can also collapse rows, filter result visibility and sort results. This makes it a stronger fit when the team needs to shape the report or attach its own artifacts rather than rely mainly on a preset overview.
How the practical differences affect your choice
| Need | What is documented | Practical choice |
|---|---|---|
| Overview, trends, history or failure screenshots | pytest-html-reporter lists these built-in features, along with suite highlights and rerun support. (PyPI project page) |
Consider it if those features match your workflow, then verify compatibility with your dependency set. |
| Custom layout or supplemental data | pytest-html documents CSS, hooks, custom table content and text, JSON, URL and image extras. (Official user guide) |
Prefer it when you need to customize report content or presentation. |
| Share a report as one file | pytest-html supports --self-contained-html, which puts CSS and assets inline. Attached image files or links may remain external and may not appear as expected in a standalone report. (Official user guide) |
Use the self-contained option when portability matters, and check that attached content is available in the resulting file. |
| Parallel execution with xdist | pytest-html describes its original sort mode as best-effort; it may not preserve execution order with pytest-xdist. (Official user guide) |
Do not rely on that mode for an exact worker completion sequence. Check the behavior you need in your own setup. |
Set up a report with either plugin
For pytest-html-reporter
- Install it with
pip3 install pytest-html-reporter. - Run pytest with
--html-reportto choose the output path or filename, and--titleto name the report. Without an overridden path, the documented default isreport/pytest_html_reporter.html. - If you want the documented options in project configuration, the package page says they can be set in
pytest.ini. Confirm the configuration in your own run.
For pytest-html
- Install it with
pip install pytest-html. - For a self-contained report, run
pytest --html=report.html --self-contained-html. Thepytest-htmluser guide documents this invocation. - If you attach images by file or link, inspect the generated report in the way recipients will open it; those images may not be embedded in the standalone file.
- Use the documented hooks, CSS, extras, visibility controls and sorting options as needed for your report. If tests run in parallel, treat
originalordering as best-effort rather than guaranteed.
Check compatibility and maintenance before adopting
Package metadata is a starting point, not a tested compatibility matrix. The pytest-html-reporter PyPI page lists Python >=3.5, while the pytest-html installation guide says Python >=3.6 or PyPy3. The official pytest plugin list lists pytest >=7 for pytest-html. These statements come from different project pages and do not establish that every listed plugin release works with every modern Python and pytest combination.

Visible release history is another signal to consider, not a compatibility or safety verdict. The pytest-html-reporter repository search result identifies v0.2.9, dated February 13, 2022, as its latest release. The pytest-html changelog records versions 4.1.1 on November 7, 2023 and 4.1.0 on November 4, 2023; that changelog snapshot does not establish which release is current today.
Before relying on either plugin, check the package metadata and release history for the versions you plan to install, then run them with your actual Python, pytest and (if applicable) xdist versions in a disposable environment or CI matrix. Confirm that the generated report contains the information you need and can be opened where it will be shared.
