Inconsistencies due to Spectra™ Rule Engine updates
The Spectra™ Rule Engine is updated regularly to improve issue detection, so scans run on different engine versions can report different issues.
Root cause and explanation
The Spectra™ Rule Engine, which works under the hood of BrowserStack Accessibility Testing, is updated regularly to improve issue detection. There could be differences in the number of issues or type of issues detected if you compare scans run on different versions of the Spectra™ Rule Engine.
Affected products
All products in BrowserStack Accessibility Testing can show inconsistencies in issue count if there were updates to the Spectra™ Rule Engine.
These products are:
- Workflow Analyzer
- Website Scanner
- Automated tests
Remediation
Retry the scan to check whether the issue persists.
If the issue persists, follow these steps to avoid changes to issue count due to an update to the Spectra™ Rule Engine:
- Check the All Issues tab to see if any of the changes in issue counts are due to the issues marked as new rules.
- Check the scanner version used for each scan.
- Review the rule update release log.
