Testing

We run integration tests for all our SDKs using a centralized test harness. This approach gives us the ability to test for consistency across SDKs. These tests cover each method in the SDK, and verify that event sending, flag evaluation, stream reconnection, and other aspects of the SDK all behave correctly.

Contributing

We encourage pull requests and other contributions from the community. Read our contributing guidelines for instructions on how to contribute to this SDK.

About LaunchDarkly

LaunchDarkly is a feature management platform. We empower all teams to deliver and control their software. With LaunchDarkly, you can:
- Roll out a new feature to a subset of your end users, such as a group of end users who opt in to a beta tester group, and gather feedback and bug reports from real-world use cases.
- Gradually roll out a feature to an increasing percentage of customers, and track the effect that the feature has on key metrics. For instance, how likely is a customer to complete a purchase if they have feature A versus feature B?
- Turn off a feature that 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 end user attributes, like payment plan. (For example, customers on the ‘gold’ plan have access to more features than customers 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. Read our SDK documentation for a complete list.
