+  summary: A pytest plugin for snapshot testing Textual applications.
+  description: |
+    A pytest-textual-snapshot test saves an SVG screenshot of a running Textual app to disk.
+    The next time the test runs, it takes another screenshot and compares it to the saved one. If the new screenshot differs from the old one, the test fails.
+    This is a convenient way to quickly and automatically detect visual regressions in your applications.
