      Here's the test with more context:

              self.assertEqual("x_1", db.test.create_index(
                  [('x', ASCENDING)], partialFilterExpression={"a": {"$lte": 1.5}}))
              db.test.insert_one({"x": 5, "a": 2})
              db.test.insert_one({"x": 6, "a": 1})
      
              # Operations that use the partial index.
              explain = db.test.find({"x": 6, "a": 1}).explain()
              stage = self.get_plan_stage(explain['queryPlanner']['winningPlan'],
                                          'IXSCAN')
              self.assertEqual("x_1", stage.get('indexName'))
      

      It looks like like either the server's explain output has changed or the query planner itself has changed.
