description: `Stop trace collection and save captured data using Skyramp's comprehensive tracing capabilities.
Stopping trace collection finalizes the monitoring process and exports all captured data to specified files. This includes API calls, service communications, user interactions, and network traffic that occurred during the collection period.
INTEGRATION WITH TEST GENERATION:
The generated trace and Playwright files can be used as inputs for:
- Integration test generation (using trace files)
- Load test generation (using trace files)
- E2E test generation (using both trace and Playwright files)
- UI test generation (using Playwright files)
For detailed documentation visit: https://www.skyramp.dev/docs/load-test/advanced-generation#end-trace-collection`,
