Load Testing

Code Archives

Integrity Checksums

To help ensure the integrity of uploaded test suites, XTC now maintains checksums for code archives.

When uploading a code archive using the REST API, you can optionally include a precalculated SHA-512 checksum by passing it in the Content-Digest HTTP header. XTC uses this digest to validate that the uploaded file has not been corrupted or tampered with during transit. If no checksum is provided, XTC will store the archive as transmitted.

For uploads initiated through the management UI, the checksum is automatically calculated from the local file before transmission begins.

Regardless of the upload method, the checksum is stored with the archive and is displayed in the list of code archives in the UI for easy verification and reference.

Private Machines (Preview)

Resource Usage Tracking

Private machines are now fully integrated into the XTC resource usage tracking system, matching the level of visibility provided for public cloud and custom machines.

This integration allows you to get a comprehensive overview of your private machine usage. You can monitor how many machines were active, when they were used, and the duration of their usage, aggregated by load test and project. This makes it easier to track and report infrastructure utilization across all load testing activities.
