Seems like a lot of the diff in diff shades only have one method call. This in particular seems especially bad:

     assert (
         makeFY5253NearestEndMonthQuarter(
             weekday=1, startingMonth=3, qtr_with_extra_week=3
-        ).freqstr
+        )
+        .freqstr
         == "REQ-N-MAR-TUE-3"
     )

Looking at the diff-shades output, a lot of changes feel like mild negatives, e.g.

         self.assertTrue(
-            logger.messages[0].startswith(
+            logger.messages[0]
+            .startswith(
                 "route matched for url http://localhost:8080"
                 "/archives/action1/article1; "
                 "route_name: 'foo', "
                 "path_info: "
             )

-        assert repr_locals.lines[0].startswith(
-            "x          = <[NotImplementedError() raised in repr()] ObjWithErrorInRepr"
+        assert (
+            repr_locals.lines[0]
+            .startswith(
+                "x          = <[NotImplementedError() raised in repr()]"
+                " ObjWithErrorInRepr"
+            )
         )
