Is your feature request related to a problem? Please describe.
Large sample/custom tests are painful to paste directly into the IDE. Showing the full text content in the input panel can also make the UI slow or hard to use when the input file is large.
Describe the solution you'd like
Allow users to choose a .txt file as test input instead of pasting all input into the text area.
Suggested behavior:
- Add an action such as
Load input from file / Attach input file for a test case.
- Run the test by streaming/feeding the selected file content to stdin.
- Show only a partial preview of the file content in the UI, e.g. first N lines/characters plus file size/path.
- Do not render the full file in the panel by default.
- Provide a way to clear/change the selected file.
- Keep normal pasted input supported for small tests.
Describe alternatives you've considered
Users can paste the full file contents into the input box, but that is slow and difficult for large inputs. They can also run outside the IDE, but that defeats the integrated testcase workflow.
Additional context
User feedback from 2026-06-01: this is a suggestion, not a bug. The user wants to input a text file and only display part of that file in the UI rather than rendering the whole file.
