order of test cases in the iteration page

Depending on the screen or area of the system you are looking at, Test cases can be sorted by any number of field, even custom fields. Also, within a test set, test case order can be customized by dragging and dropping the test case to change its order within the set.

This behavior is typically due to default sorting in the iteration view. To fix it, check if your tool supports custom test case ordering or folder-based grouping in iteration settings. If not, consider tagging or prefixing test cases to enforce manual order. Some platforms also allow sorting by execution sequence or priority—worth exploring in your test management tool.
