| PASS | On getting, the length attribute must return the number of nodes represented by the collection. | |
| FAIL | Changing the length adds new nodes; The number of new nodes = new length minus old length | assert_equals: Number of nodes in collection should have changed expected 7 but got 4 |
| FAIL | New nodes have no value | Cannot read properties of undefined (reading 'value') |
| FAIL | Setting a length equal to existing length changes nothing | assert_equals: Number of nodes in collection should not have changed expected 7 but got 4 |
| PASS | Setting a length lower than the old length trims nodes from the end | |
| FAIL | Setting element to null by index removed the element | assert_equals: Number of nodes in collection is correctly changed expected 3 but got 4 |
| FAIL | Setting element by index should correctly append and replace elements | Cannot read properties of undefined (reading 'value') |
| FAIL | Changing the length adds new nodes; The new nodes will not copy select's prefix | assert_equals: Number of nodes in collection should have changed expected 5 but got 0 |
