<h2>New features</h2>
<ul>
<li>
<p><a
href="https://redirect.github.com/pytest-dev/pytest/issues/1367">#1367</a>:
<strong>Support for subtests</strong> has been added.</p>
<p><code>subtests &lt;subtests&gt;</code> are an alternative to
parametrization, useful in situations where the parametrization values
are not all known at collection time.</p>
<p>Example:</p>
<pre lang="python"><code>def contains_docstring(p: Path) -&gt; bool:
&quot;&quot;&quot;Return True if the given Python file contains a
top-level docstring.&quot;&quot;&quot;
    ...
<p>def test_py_files_contain_docstring(subtests: pytest.Subtests) -&gt;
None:<br />
for path in Path.cwd().glob(&quot;*.py&quot;):<br />
with subtests.test(path=str(path)):<br />
assert contains_docstring(path)<br />
</code></pre></p>
