Trial Results Tab¶
Advanced Mode Required
This tab is only visible when Advanced Mode is checked in the toolbar. Enable it to access Verification, Trial Results, and Model Text.
The Trial Results tab shows detailed information about each parallel trial that was run during generation.
What Are Trials?¶
When ProTest generates a covering array, it runs multiple independent trials in parallel — each using a different random seed. The trial that produces the smallest result (fewest test cases) is kept as the final output.
The Trial Results tab lets you see exactly what happened during each trial.
Trial Information¶
For each trial, the tab shows:
| Column | Description |
|---|---|
| Trial Number | Sequential identifier |
| Seed | The random seed used for this trial |
| Engine | Which engine was used (PICT or SIPO) |
| Test Cases | Number of test cases produced |
| Elapsed Time | How long this trial took |
| Status | Success or failure |
| Best | Whether this trial produced the winning (smallest) result |
Why This Matters¶
Trial Results help you:
- Understand variance — See how much results vary across random seeds
- Tune performance — Decide whether more trials would likely find a better result
- Debug issues — If some trials fail, their error information appears here
- Compare engines — If using mixed trials, see how PICT and SIPO compare on your specific model
