Stress Test (Beta)
Designers design for the happy path — short, perfectly wrapped text. But what happens when that button gets translated to German? What happens if a username is 3× longer than expected?
The Stress Test module simulates real-world edge cases without touching your original components.
How it Works
- Select a component or frame on the canvas.
- Click "Run Stress Test" — the plugin creates a dedicated sandbox page and clones your component into labeled scenario columns.
- Simulate — each column applies a different stress scenario to the clone.
- Detect — the plugin scans the clones for
TEXT_OVERFLOW,CLIPPING, andLAYOUT_BREAKissues with confidence levels. - Review — inspect the columns on the sandbox page, then clear when done.
Your original design is never modified.
Built-in Scenarios
Without any AI connection, the module runs heuristic scenarios:
- 3× Text — multiplies all text content to simulate long user-generated strings
- Narrow Viewport — forces the component into a constrained width
- Empty State — clears text to test minimum-content layouts
- All Caps — simulates uppercase label transforms
AI-Enhanced Scenarios (BYOK)
Connect an AI provider in Settings to unlock content-aware scenario generation. Instead of generic text repetition, the AI analyzes the semantic purpose of your component and generates realistic edge cases:
- If it's a user profile card: edge-case real names (long surnames, CJK characters, emojis)
- If it's a price tag: large numbers, currency symbol variations, locale formatting
- If it's a notification banner: legally mandated disclosure text, multi-line alerts
Supported AI providers:
| Provider | Models |
|---|---|
| Anthropic | Claude Opus 4.8, Sonnet 4.6, Haiku 4.5 |
| OpenAI | GPT-4.1, GPT-4o, o3, o1 |
| Google Gemini | Gemini 2.0 Flash, Gemini 1.5 Pro |
| Groq | Llama 3, Mixtral |
| Mistral | Mistral Large, Codestral |
| xAI | Grok 3, Grok 2 |
| Together AI | Open-source model fleet |
| Custom | Any OpenAI-compatible endpoint |
AI scenarios are cached per component. Re-running the stress test on the same component reuses cached scenarios — no extra API calls.
Fix Simulation
When an issue is detected on a clone, click Simulate Fix. The plugin attempts structural corrections (adjusting text wrapping, changing Auto Layout sizing modes, adding truncation) and reports the outcome:
| Outcome | Meaning |
|---|---|
| Resolved | Issue no longer detected after fix |
| Improved | Issue reduced in severity |
| No Change | Fix had no measurable effect |
| Worse | Fix introduced a new issue |
Review outcomes in the sandbox before deciding to apply the fix to your original master component.
Dev Mode
The Stress Test module is blocked in Figma Dev Mode — cloning and page creation require write access, which Dev Mode does not grant.
