For non-JSON APIs or as complementary validation, text search in the body detects masked errors and unexpected content.
An API can return 200 OK with an error message in the body.
Why Validate Content
- Masked errors: some APIs return 200 with "error" in the body.
- Maintenance pages: detect "maintenance" or "temporarily unavailable".
- Dynamic content: verify a key element is present in the response.
Configuration
- Expected text: configure text that must be present (e.g., "success").
- Forbidden text: alert if "error", "exception", "maintenance" appears.
