Launchable CLI
Decision gist · record as of 2026-08-14
Yes, if you are running large test suites in CI/CD and want to reduce feedback time through intelligent test selection. The package is actively maintained, has low install friction, carries no known vulnerabilities, and uses a permissive license. The main requirement is that your environment supports both Python 3.6+ and Java 8+, and you have a Launchable account to connect to. If your test infrastructure is small or test execution is not a bottleneck, the overhead of integration may not justify the benefit.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Java 8 or later and Python 3.6 or later; the CLI depends on an embedded Java component (exe_deploy.jar) for core functionality.
- Low install friction with a pure-Python wheel distribution.
- The package is actively maintained with a recent release (59 days ago) and relies on common, stable dependencies like click, requests, and junitparser.

What it is and what it does
Launchable CLI is a command-line interface for the Launchable test optimization platform. It integrates into CI/CD pipelines to intelligently select which tests to run based on code changes and historical test data, aiming to reduce overall test execution time and feedback latency. The tool parses test results (via junitparser), communicates with the Launchable backend service over HTTP, and provides commands to configure and manage test runs.
The package bundles a Java component (exe_deploy.jar) alongside Python code, making it a hybrid tool that requires both Python 3.6+ and Java 8+ to operate. It uses standard CLI patterns via click and integrates with common testing workflows by reading and reporting JUnit XML test results. The tool is designed for teams running large test suites in continuous integration environments where test execution time is a bottleneck.
Use it for
- Reduce CI/CD feedback time by running only tests likely affected by recent code changes.
- Integrate test optimization into existing Jenkins, GitHub Actions, or other CI platforms via CLI commands.
- Collect and analyze test execution data to identify slow or flaky tests over time.
- Manage test configurations and report results back to Launchable's analytics backend.
- Automate test selection in monorepo or multi-service environments with complex test dependencies.
