# SDK test harness
[](https://github.com/launchdarkly/sdk-test-harness/actions/workflows/ci.yml)
This tool runs standardized test suites for LaunchDarkly SDKs.
To use the test harness for any given SDK, we must implement a small web service that exercises the features of the SDK. The behavior of the service endpoints is described below. After starting the service, run the test harness and give it the base URL of the test service. The test harness will start its own HTTP server to provide simulations of LaunchDarkly endpoints; it will tell the test service to create SDK client instances that connect to those endpoints.

# About LaunchDarkly
* LaunchDarkly is a continuous delivery platform that provides feature flags as a service and allows developers to iterate quickly and safely. We allow you to easily flag your features and manage them from the LaunchDarkly dashboard. With LaunchDarkly, you can:
* Roll out a new feature to a subset of your users (like a group of users who opt-in to a beta tester group), gathering feedback and bug reports from real-world use cases.
* Gradually roll out a feature to an increasing percentage of users, and track the effect that the feature has on key metrics (for instance, how likely is a user to complete a purchase if they have feature A versus feature B?).
* Turn off a feature that you realize is causing performance problems in production, without needing to re-deploy, or even restart the application with a changed configuration file.
* Grant access to certain features based on user attributes, like payment plan (eg: users on the ‘gold’ plan get access to more features than users in the ‘silver’ plan). Disable parts of your application to facilitate maintenance, without taking everything offline.
* LaunchDarkly provides feature flag SDKs for a wide variety of languages and technologies. Check out [our documentation](https://docs.launchdarkly.com/docs) for a complete list.
