CuraCourseWhat this block does
The Code Editor gives students a file workspace inside the lesson. Configure the exercise’s environment, starter files, and run command, then add grading criteria for the behavior you want to check.
Build the workspace
- Insert Code Editor and write the task.
- Add your starter files with the correct file paths.
- Mark files read-only when students should inspect them without changing them. Mark files hidden when they should not appear in the student workspace.
- Choose the execution environment and set the run command for the project.
- Decide whether to allow pasting in the editor.
Add an output test
A code grading criterion has its own points, environment, run command, standard input, and expected output. Comparison can be exact, regex, or partial. Case and whitespace handling are configurable; Show diff controls the output comparison display.
For a Python program that doubles a number read from standard input, a criterion could use:
Run command: python main.py
Standard input: 4
Expected output: 8
Comparison: exact
Add another criterion with a different input to test another case. This is an example configuration, not a preinstalled test suite.
Check before assigning
Run the starter project and a known-correct solution. Confirm that the command uses the right file path and that your expected output matches the program’s actual output, including prompts and line breaks.
Troubleshooting
If a test fails despite a correct calculation, inspect extra printed text and whitespace. If the program waits indefinitely, check whether it expects standard input that the criterion does not provide. A hidden file is a visibility setting; it does not automatically become a grading criterion.
