Tricentis Sealights Python Agent - Quality Intelligence and Code Coverage
Decision gist · record as of 2026-08-14
Yes, if you have a Tricentis Sealights subscription and need integrated code coverage collection with test impact analysis in a CI/CD pipeline. The package is actively maintained, has low install friction, and supports modern Python versions. However, the proprietary license requires review before adoption, and you must verify compatibility with your specific CI/CD platform and test framework. Not suitable for projects seeking open-source or license-flexible coverage tooling.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later (3.10, 3.11, 3.12, 3.13, 3.14).
- Requires a Tricentis Sealights account and authentication token (sltoken.txt).
- Low install friction with a pure-wheel distribution.

What it is and what it does
The sealights-python-agent is a Tricentis-provided instrumentation agent that hooks into Python test execution to collect per-test method-level code coverage and report it to the Sealights Quality Intelligence Platform. It works by scanning your source code to establish a build baseline, instrumenting test runs to capture coverage, and optionally running Test Impact Analysis to identify which tests are affected by recent code changes—allowing you to skip unaffected tests and reduce CI cycle time.
The agent supports pytest, unittest, unittest2, Behave, Robot Framework, and nose (on Python 3.11 and earlier). It operates via CLI commands (sl-python scan, start, end) and integrates with your existing test infrastructure through environment variables and configuration files. Installation is straightforward, and the package carries 17 runtime dependencies including cryptography, requests, and GitPython for secure communication and repository introspection.
Use it for
- Reduce CI/CD cycle time by running only tests affected by recent code changes using Test Impact Analysis.
- Collect per-test method-level coverage data across multiple test frameworks in a single pipeline.
- Track code coverage trends and quality metrics across builds and branches in the Sealights dashboard.
- Integrate code coverage and test optimization into existing pytest, unittest, or Behave workflows.
- Identify untested code paths and gaps in test coverage for quality assurance teams.
