Tricentis Sealights Python Agent
The sealights-python-agent integrates your Python applications with the Tricentis Sealights Quality Intelligence Platform. It provides real-time code coverage analysis, test optimization, and quality analytics for your CI/CD pipelines.
With this agent you can:
Scan builds – map your source code so Sealights can track changes across builds and branches.
Collect code coverage – capture per-test method-level coverage during test execution.
Optimize testing – leverage Sealights Test Impact Analysis to run only the tests affected by recent code changes, reducing CI cycle time.
Compatibility
Python 3.10, 3.11, 3.12, 3.13, 3.14
Test frameworks: pytest, unittest, unittest2, Behave, Robot Framework, nose (on Python 3.11 and earlier)
