<p>我认为你不想隐藏所有的警告，只想隐藏那些不相关的警告。在本例中，来自导入的python模块的deprectation警告。</p>
<p>阅读关于<a href="https://docs.pytest.org/en/latest/warnings.html" rel="noreferrer">Warnings Capture</a>的pytest文档：</p>
<blockquote>
<p>Both -W command-line option and filterwarnings ini option are based on Python’s own <a href="https://docs.python.org/3/using/cmdline.html?highlight=#cmdoption-W" rel="noreferrer">-W option</a> and <a href="https://docs.python.org/3/library/warnings.html#warnings.simplefilter" rel="noreferrer">warnings.simplefilter</a>, so please refer to those sections in the Python documentation for other examples and advanced usage.</p>
</blockquote>
<p>所以你可以用python的<code>-W</code>选项过滤警告！</p>
<p>似乎<code>pytest</code>完全删除了过滤器，因为它在运行时显示了所有那些<code>DeprecationWarning</code>，而Python关于<a href="https://docs.python.org/3/library/warnings.html#default-warning-filter" rel="noreferrer">Default Warning Filters</a>的文档清楚地表明：</p>
<blockquote>
<p>In regular release builds, the default warning filter has the
following entries (in order of precedence):</p>
<pre><code>default::DeprecationWarning:__main__
ignore::DeprecationWarning
ignore::PendingDeprecationWarning
ignore::ImportWarning
ignore::ResourceWarning
</code></pre>
</blockquote>
<p>因此，在您的例子中，如果您想要过滤您想要忽略的警告类型，比如那些<code>DeprecationWarning</code>，只需使用<code>-W</code>选项运行pytest命令：</p>
<pre><code>$ pytest path-to-test-folder -W ignore::DeprecationWarning
</code></pre>
<p><strong>编辑</strong>：根据<a href="https://stackoverflow.com/users/825105/colini">colini</a>的注释，可以按模块筛选。忽略来自所有sqlalchemy的不推荐警告的示例：</p>
<pre><code>ignore::DeprecationWarning:sqlalchemy.*:
</code></pre>
<p>然后，您可以列出已安装的模块，这些模块会在<code>pytest</code>的输出中产生过多的噪声</p>
<p><strong>与文件一起使用，而不是在命令行中使用：</strong></p>
<p>您可能希望在pytest.ini文件中列出这些筛选器：</p>
<pre><code>[pytest]
filterwarnings =
ignore::DeprecationWarning
</code></pre>
