9.2.0

pytest 9.2.0 (2026-10-27)

Removals and backward incompatible breaking changes

• #14716: -c now raises a usage error for a path that does not exist, is a directory, or is in a format pytest has no loader for. Such paths were previously either ignored or reported as an unhandled FileNotFoundError.

• #8593: The indirect, ids and scope arguments of Metafunc.parametrize() <pytest.Metafunc.parametrize> -- and therefore of @pytest.mark.parametrize <pytest.mark.parametrize ref> -- are now keyword-only.

  Passing them positionally was a common source of confusing errors, e.g. parametrize("arg1", "arg2", [(1, 2)]) made the argvalues land in indirect and failed with indirect fixture '(1, 2)' doesn't exist; such mistakes now fail with an understandable TypeError. The type annotations have always declared these arguments as keyword-only.

• #993: Plugin import failures at startup are now reported and classified instead of escaping as a raw traceback with the accidental exit code 1:

  • a plugin that cannot be found -- via -p, pytest_plugins or PYTEST_PLUGINS -- exits with pytest.ExitCode USAGE_ERROR (4), like a conftest.py that fails to import;
  • a plugin that is found but raises while importing -- including a broken pytest11 entry point or a missing plugin dependency -- exits with pytest.ExitCode INTERNAL_ERROR (3), with the traceback preserved.

  pytest.main now returns these codes instead of raising ImportError. Also fixed an IndexError from pytest's own internals when the plugin raised an exception with no arguments.

Deprecations (removal in next major release)

• #14742: The private _pytest.python.CallSpec2 name has been renamed to CallSpec. The old CallSpec2 alias remains available for now and will be removed in pytest 10 or 11.

• #14755: Schedule yield_fixture decorator for removal in pytest 10 or 11.

• #14774: Similarly to the deprecation of class-scoped fixtures defined as instance methods in pytest 9.1, all higher-scoped fixtures (module, package, and session) defined as instance methods are now deprecated.

  They suffer from the same issue the original deprecation only fixed for class-scoped fixtures, see 10819 and 14011.

• #14808: Passing a non-string value to a string-typed ini option now emits a pytest.PytestRemovedIn10Warning. This affects [tool.pytest.ini_options] in pyproject.toml. In pytest 10 this will raise a TypeError, matching the behavior of the corresponding TOML config path.

• #7323: Passing bytes to TerminalReporter.write_line() is now deprecated, pass a str instead.

New features

• #14743: Full diff: now contains a legend explaining the + & - symbols in diff output.
• #2781: When strict_markers is enabled, marker names used in -m expressions are now validated against registered markers.
• #6881: Added the parametrize_long_str_id_strategy configuration option to control how long str/bytes parameter values are handled in auto-generated test IDs. Explicit IDs set via ids=[...] or pytest.param(..., id=...) are not affected. Available strategies: short (default, values over 100 chars fall back to argname+index), sha256 (SHA-256 hex digest), legacy (keep full value), and disallow (error requesting explicit IDs).

Improvements in existing functionality

• #10745: A RecursionError whose recursion origin cannot be located now shows only the first and last 10 stack frames, matching what pytest already did when locating the origin failed outright. Previously the full traceback -- often around a thousand near-identical frames -- was rendered, which was both slow and unreadable. Pass --full-trace to see every frame.

v1.64.1

Highlights

microsoft/playwright-python#3283 - chore: roll Node.js to 24.22.1

The bundled Node.js 24.22.1 is a security release that distrusts the compromised eMudhra intermediate CAs. The driver uses Node's CA store for its own TLS connections, for example connect_over_cdp to a wss:// endpoint.

Browser Versions

• Chromium 156.0.8078.4
• Mozilla Firefox 157.0
• WebKit 27.2

This version was also tested against the following stable channels:

• Google Chrome 155
• Microsoft Edge 155

v1.64.0

🧰 WebMCP

New page.webmcp and frame.webmcp give access to the tools that a page registers through the experimental WebMCP browser API, so you can test them like any other part of your app:

browser = chromium.launch(args=["--enable-features=WebMCP"])
page = browser.new_page()
page.goto("https://example.com")
for tool in page.webmcp.tools():
print(tool["name"], tool["description"])
result = page.webmcp.call_tool("add", {"a": 2, "b": 40})
print(result["content"][0]["text"])  # "42"

Playwright MCP also supports WebMCP by default, with page-defined tools offered to the agent as webmcp_<tool>. Pass --no-webmcp to opt out.

playwright-cli exposes them as well:

playwright-cli webmcp-list
playwright-cli webmcp-call search_catalog --params '{"query":"cats"}'
